(Summary) The dehydrogenation of isobutane in the presence of CO2 over NiO supported on γ-Al2O3 was examined. For comparison, Cr2O3 supported on γ-Al2O3 was also used. It is generally accepted that a catalyst used for the dehydrogenation of various alkanes will suffer catalyst deactivation due to the formation of carbon deposits. In the present study, the yield of isobutene was significantly decreased with time-on-stream due to carbon deposition when using Cr2O3(x)/γ-Al2O3, in which x indicates the loading of a corresponding oxide by weight %. However, carbon deposits also were evident on NiO(x)/γ-Al2O3, but the yield of isobutene was enhanced with time-on-stream depending on the loading (x). This indicates that the contribution of the carbon deposition in the dehydrogenation on NiO(x)/γ-Al2O3 definitely differed from that on an ordinary catalyst system such as Cr2O3(x)/γ-Al2O3. In order to confirm the advantageous effect that carbon deposition exerted on the yield of isobutene, NiO(x)/γ-Al2O3 was first treated with isobutane and then the catalytic activity was examined. As expected, it became clear that the carbon deposits formed during the pretreatment contributed to the enhancement of the yield of isobutene. The presence of a Ni-carbide species together with the metallic Ni that was converted from NiO during dehydrogenation definitely enhanced of the yield of isobutene. Although carbon deposition is generally recognized as the main cause of catalyst deactivation, the results of the present study reveal that carbon deposition is not necessarily the cause of this phenomenon.

(Summary) In order to utilize chicken manure as a source of phosphorus, we used dissolution-precipitation treatment to recover phosphorus from the incineration ash of chicken manure (IACM), which was used as fuel to power a boiler. In order to recover useful phosphorus-containing solids from IACM, it was dissolved into aqueous solutions of either nitric acid, hydrochloric acid, or sulfuric acid to elute phosphorus together with various component elements, followed by the use of aqueous NH3 to form a precipitate containing phosphorus. In using nitric acid and hydrochloric acid, calcium phosphate species such as calcium hydroxyapatite (Ca10(PO4)6(OH)2) and monetite (CaHPO4) were obtained following the precipitation treatment. By contrast, the use of sulfuric acid resulted in the precipitation of magnesium ammonium phosphate (MAP) species such as struvite (MgNH4PO4∙6H2O) and dittmarite (MgNH4PO4∙H2O). Both the calcium phosphate and MAP species can be used as a slow-acting fertilizer containing phosphorus, while the MAP species could be simultaneously used as a slow-acting fertilizer containing nitrogen. It is noteworthy that the calcium phosphate species obtained in the present study was equivalent to phosphate rock, which is widely used as a raw material in phosphorous-based industries, and the natural sources of this material could be depleted in the near future. Though IACM has not been used effectively until now, this new resource shows promise as s viable alternative to the dwindling supply of the natural sources of phosphorus.

Shigeru Sugiyama, Mika Miyake, Mizuho Yoshida, Yuki Nakao, Naohiro Shimoda and Masahiro Katoh : Effect of Cerium Addition to Bismuth-molybdenum Complex Oxide Catalyst for Partial Oxidation of Propylene to Acrolein, Journal of the Japan Petroleum Institute, Vol.63, No.5, 267-272, 2020. (Summary) Ce addition to a Bi-Mo complex oxide catalyst supported on SiO2 was examined for its effect on the partial oxidation of propylene to acrolein. The catalyst consisted of an oxygen-supply phase where the lattice oxygen in Mo-oxide was doped with transition metals such as Fe, Ni and Co and was supported by SiO2 and a catalytic-active phase that involved hydrogen-abstraction from a reactant in the Bi-center of Bi-Mo oxide, which was supported by an oxygen-supply phase. In the present study, Ce was added during the oxygen-supply phase in order to enhance its redox nature. An advanta-geous effect of Ce addition was observed particularly under oxygen-rich conditions in the feed stream. For example, at P(C3H8) = 10.1 kPa and P(O2) = 15.5 kPa at 623 K, the yield of acrolein was slightly enhanced from 57.6% with 0% Ce doping to the catalyst to 65.3% with 20% Ce doping to the catalyst at 6 h on-stream. However, under greater oxy-gen-rich conditions at P(C3H8) = 10.1 kPa and P(O2) = 31.0 kPa at 623 K, the yield of acrolein was enhanced approxi-mately twice from 27.7% with 0% Ce doping of the catalyst to 61.8% with 20% Ce doping of the catalyst at 6 h on-stream. Analysis using XPS for the catalysts previously used for the reaction in the absence of gaseous oxygen con-firmed the unique redox behavior between the catalytic-active phase and the oxygen-supply phase as the lattice oxygen in the catalytic-active phase was replenished from the oxygen-supply phase to maintain its surface properties over the catalytic-active phase. The XPS results and the remarkable effect of Ce addition to the oxygen-supply phase under ox-ygen-rich conditions confirmed the correctness of the concept of the catalyst preparation consisting of an oxy-gen-supply phase and a catalytic-active phase was correct.

(Summary) There are active oxygen species that contribute to oxidative coupling or the partial oxidation during the oxidative dehydrogenation of methane when using solid oxide catalysts, and those species have not been definitively identified. In the present study, we clarify which of the active oxygen species affect the oxidative dehydrogenation of methane by employing photo-catalysts such as TiO2 or WO3, which generate active oxygen from UV-LED irradiation conditions under an oxygen flow. These photo-catalysts were studied in combination with Sm2O3, which is a methane oxidation coupling catalyst. For this purpose, we constructed a reaction system that could directly irradiate UV-LED to a solid catalyst via a normal fixed-bed continuous-flow reactor operated at atmospheric pressure. Binary catalysts prepared from TiO2 or WO3 were either supported on or kneaded with Sm2O3 in the present study. UV-LED irradiation clearly improved the partial oxidation from methane to CO and/or slightly improved the oxidative coupling route from me-thane to ethylene when binary catalysts consisting of Sm2O3 and TiO2 are used, while negligible UV-LED effects were detected when using Sm2O3 and WO3. These results indicate that with UV-LED irradiation the active oxygen of O2 from TiO2 certainly contributes to the activation of methane during the oxidative dehydrogenation of methane when using Sm2O3, while the active oxygen of H2O2 from WO3 under the same conditions afforded only negligible effects on the activation of methane.

(Summary) Porous stainless steel (SUS) supports were modified with double intermediate layers, silicalite-1 and -alumina, to enhance the hydrogen diffusion of a thin palladium membrane. One of layers, silicalite-1, was prepared using the hydrothermal synthetic method on porous SUS supports. The differences in expansion/contraction behaviors caused by different thermal coefficients of expansion between silicalite-1 and the SUS resulted in a lowering of the durability of the membrane. Intermediates layers of mesoporous MCM-48 powders or commercial spherical non-porous silica particles were then applied to porous SUS supports via aspiration, -alumina was introduced by dip-coating, and the Pd membrane was subjected to electro-less plating. H2 permeance of the Pd membrane (membrane thickness: 11 m) containing spherical silica particles was around 10x10-6 molm-2s-1Pa-1 at 600°C, which was higher than that of the Pd membrane (membrane thickness: 7 m) containing MCM-48. The durability of the Pd membrane containing spherical silica particles was higher than that of the version containing MCM-48 powders. These results suggest that commercial spherical non-porous silica particles will uniformly occupy the pores of the SUS tubes and enhance the H2 permeance and durability of the Pd membrane.

(Summary) Commercial silicoaluminophosphate molecular sieves (SAPO-34) received alkali treatment with either NaOH (0.2, 0.01, 0.005, or 0.001 M) or NH4OH (0.005 M). Treatment with NaOH (0.005 M) increased the water adsorption initial rate of SAPO-34 by 1.4-fold. The alkali treatment introduced Na+ adsorption sites into the SAPO-34. The desorption ratio (adsorption at 30 and desorption at 100) was 88.2% higher than the original rate (84.3%). On the other hand, after alkali treatment of SAPO-34 using NH4OH (0.005 M), calcination resulted in the highest desorption ratio at 91.3%. When combined with calcination, alkali treatment with NH4OH introduced H+ adsorption sites into SAPO-34, H+ adsorption sites feature low levels of interaction with water, which enhanced the desorption ratio, but decreased the initial adsorption rate. These results indicate that treating commercial SAPO-34 with 0.005 M NaOH enhances both the adsorption and desorption behaviors.

(Summary) In order to obtain calcium phosphates - a phosphate rock equivalent - from the incineration ash of chicken manure, which is obtained from power generation systems that use the manure for fuel, incineration ash was treated with an aqueous solution of nitric acid to elute phosphorus. By using 0.3 M of HNO3, most of the phosphorus could be eluted from 1.0 g of ash within 0.1 h. Compared with the composted chicken manure that was previously examined in our laboratory, the concentration of HNO3 was increased for this session of elution. Using the incineration ash of chicken manure made it possible to remove inorganic species at a lower boiling or sublimation temperature, and organic species by calcination in the power generation system. Compared with composted chicken manure, the concentrations of phosphorus contained in the incineration ash and the nitric acid extract were higher in the incineration ash. XRD analysis showed that the obtained nitric acid extract could be treated with aqueous NH3 to form a precipitation of poorly-crystallized calcium hydroxyapatite (Ca10(PO4)6(OH)2), which is one of main components in phosphate rock. In order to confirm the formation and purity of calcium phosphate species, the precipitation calcination was conducted at 1,078 K for 5 h. XRD revealed that the calcined solid was tricalcium phosphate, and no contamination was evident. These results reveal that a phosphate rock equivalent could be easily obtained from the incineration ash of chicken manure, which means that approximately 14% of the phosphate rock that is currently being imported into Japan could be replaced by this product.

(Summary) In the present study, the production of propylene oxide (PO) from propylene via gas phase epoxidation was investigated using various catalysts. Although Ag is known to be a highly active catalyst for the epoxidation of ethylene, it was not active in the present reaction. Both Al and/or Ti showed high level of activity, however, which resulted in confusion. The present study was conducted to solve such confusion. The intent of the present study was to solve such confusion. Although the employment of MCM 41 modified with Ti and/or Al was reported as an active catalyst for epoxidation, the combination resulted in a formation of PO that amounted to less than a 0.1% yield. Since this research revealed that the acidic catalyst seemed favorable for the formation of PO, versions of ZSM 5 that were both undoped and doped with Na, Ti and Ag were used as catalysts. In these cases, small improvements of 0.67 and 0.57% were achieved in the PO yield on H ZSM 5 and Ti ZSM 5. Based on the results of the Ti dopant and acidic catalysts, Ag metal doped on carbonate species with a smaller surface area was used as a catalyst. As reported, Ag Na/CaCO3 showed a greater yield of PO at 1.29%. Furthermore, the use of SrCO3 for CaCO3 resulted in a further improvement in the PO yield to 2.17%. An experiment using CO2 and NH3 pulse together with SEM and TEM examinations for Ag Na/CaCO3 revealed that the greatest amount of activity was the result of the greater particle size of metallic Ag rather than the acid base properties of the catalysts.

(Summary) In the oxidative dehydrogenation of isobutane to isobutene, selectivity and stability were improved by introducing chromium and molybdenum into SBA-15. The direct synthesis method (DM) was used to introduce these binary elements into SBA-15. Use of the DM resulted in a higher specific surface area of the catalyst and a greater dispersion of chromium and molybdenum species compared with a corresponding binary catalyst prepared using the incipient wetness impregnation method (IM). Selectivity to isobutene was improved, along with a decrease in the selectivities to CO and CO2 with the introduction of greater amounts of molybdenum, which suggests that molybdenum must suppress the tendency of isobutene to over-oxidate to either CO or CO2. The molybdenum species must be in close proximity to the chromium species, which results in the formation of an active Cr-O-Mo site.

(Summary) Aluminophosphate molecular sieves (AlPO-5) were substituted with seven metals (Ca, Co, Mg, Ni, Sr, Cr and Fe). From XRD measurement, all patterns of seven substituted AlPO-5 were identical to that of the AFI structure. Except for Cr substituted for AlPO-5, they were mainly in a hexagonal pillar structure from SEM images. For Mg, Ni, Sr and Fe substituted for AlPO-5, the water adsorption capacity at 30 and the difference in the amount of adsorbed water between 30 (adsorption temperature) and 100 (desorption temperature) increased by the substitution. Although, for Fe substituted AlPO-5, the initial water adsorption rate was slightly decreased by the substitution, the water desorption temperature was equal for the temperature of AlPO-5. Because Fe substituted for AlPO-5 had about 1.8 times of water adsorption capacity at 30 and were able to be regenerated at 100, Fe substituted for AlPO-5 was most advantageous adsorbents.

(Summary) The catalytic performance of MCM-48 was greatly improved by the introduction of a small amount of chromium during the oxidative dehydrogenation of isobutane. Various characterization procedures such as XRD, N2 adsorption-desorption isotherms, TEM, NH3-TPD, XPS, and XAFS were used to clarify the role that chromium played in the improvement, and XPS and XAFS returned the most valuable information. Both measurements revealed that the chromium species existed as Cr6+ inside the framework of MCM-48 before oxidative dehydrogenation, but was reduced to Cr3+ during the reaction. The characteristic pore nature of MCM-48 also contributed to an enhancement of the selectivity to isobutene via a suppression of any consecutive oxidation reactions.

(Summary) A Si/SiC ceramic filter was used to support a structural palladium catalyst in a continuous fixed-bed flow reactor during a reductive decomposition of nitrite. A previous report described the use of non-porous alumina spheres coated with Pd/C, a carbon monolith impregnated with Pd or a structural catalyst consisting of a polyurethane sponge skeleton impregnated with Pd resulted either in negligible activity or a complete stoppage of the flow by increasing the pressure drop in the flow system. The use of a Si/SiC filter impregnated with palladium, however, overcame the demerits and resulted in an 11% conversion of nitrite in 60 min. The use of a Si/SiC filter coated with a char intermediate followed by impregnation with Pd (Pd/C/Si/SiC) resulted in a structural catalyst that enhanced the activity to yield a 33% conversion of nitrite in 60 min. When five Pd/C/Si/SiC structural catalysts were used, however, the complete decomposition was achieved in the same amount of time. Although improvement was previously observed by using an alumina intermediate, use of the char intermediate resulted in a new factor for activity improvement. The characterization results show that it was the affinity between aqueous nitrite and the intermediate rather than palladium dispersion that contributed the most to the improvement of activity.

(Summary) The thermal characteristic of a plate evaporator for boiling water have been experimentally investigated. Stainless-steel plates with five kinds of surface roughness (a mirror-polished surface and four kinds of polished plate surface, F2, F0, F-1, and F-2 polishing) were used for the investigation. The roughness order is F-2>F-1>F0>F2>mirror. The local boiling heat transfers were measured on the evaporator surface using ten thermocouples inside the evaporator. For a comparison of the heat transfer characteristic of the evaporator, the local boiling heat transfer coefficient was measured when the polishing direction was perpendicular or parallel to the water flow at a range of pressures (0.30.4MPa) and flow rates (2060mL/min). The results indicate that the local heat transfer coefficient increased with increasing vapor quality at all surface conditions. For F0 polishing, the heat transfer coefficient on the surface with perpendicular polishing was much larger than that on the surfaces with parallel and mirror polishing. In particular, the heat transfer coefficient of the perpendicularly polished surface (F2 and F0 polishing) was increased six-fold in comparison with that of the mirror surface at a vapor quality of 0.35. However, for the F-1 and F-2 perpendicularly polishing plates, the heat transfer coefficients were smaller than those of the F0 and F2 perpendicularly polishing plates. For the F2 perpendicularly polished plate, heat transfer enhancement was confirmed, along with an increase in the number of bubbling points, on increasing the system pressure. For the polished surface, the heat transfer coefficient increased with increasing flow rate. This indicates that the bubble formation cycle was promoted by an increased flow rate.

(Summary) Various solid oxide catalysts are active in the oxidative dehydrogenation of propane, but when these were used for the oxidative dehydrogenation of isobutane to isobutene, the yield was less than 2%. An improved yield of isobutene to 8% was obtained in the oxidative dehydrogenation of isobutane using folded-sheet mesoporous material (FSM-16) and mesoporous molecular sieve (MCM-41), either added or unadded with chromium via impregnation or template ion exchange methods. Further activity enhancement, however, could not be attained. In the present study, in order to introduce chromium cations into the framework of SBA-15 using a direct synthesis method, chromium nitrate was mixed with TEOS in an aqueous starting solution with pH adjusted to 1.5, which was followed by the hydrothermal treatment. Loading the resultant catalyst, SBA-15, with a small amount of chromium (1.84 wt% Cr-SBA-15) returned a greater yield of isobutene (15.4%) at 723 K, although previous report showed that SBA-15 supported with chromium oxide (CrOx/SBA-15) prepared via incipient wetness impregnation showed a lower yield of isobutene (11%) at 813 K. In order to explain such an improvement, the catalysts were characterized using XRD, TEM, N2 adsorption-desorption and NH3 temperature-programmed desorption. A substantial amount of specific surface area (1,610 m2/g) was detected in active Cr-SBA-15, although the structural and acidic nature of the catalyst showed the general properties of other mesoporous silicas. It is possible that when the Cr6+ species is converted from Cr3+, the great specific surface area of Cr-SBA-15 could be a factor in the oxidative dehydrogenation of isobutane to isobutene.

(Summary) In order to decompose trace amounts of nitrite in drinking water under mild conditions, a fixed-bed filtering system that used structural catalysts was employed to filter recycled aqueous nitrite. High performance and continuous mass processing are generally accepted as requirements to catalyze the decomposition of aqueous nitrite. However, the use of a fixed-bed operation when recycling aqueous nitrite with palladium catalyst systems could result in either negligible activity when using a carbon monolith impregnated with Pd, or could stop the flow by enhancing the pressure drop when using non-porous alumina spheres coated with Pd/C or structural catalysts consisting of a polyurethane sponge skeleton impregnated with Pd. In the present paper, a Si/SiC ceramic filter was employed as a structural support to prevent pressure drop. When palladium was loaded onto the surface of the filter via electroless plating, continuous flow suitably continued, and the conversion of nitrite was 45% after 60 min. In contrast, when palladium was loaded after the coating of the filter with alumina, complete decomposition was achieved after 60 min under conditions corresponding to those used for the former system. X-ray diffraction, an N2 adsorption-desorption measurement, scanning-electron microscopy, and energy-dispersive X-ray spectroscopy analyses revealed that a higher dispersion of palladium on the latter structural catalyst resulted in the greatest level of activity for the reductive decomposition of aqueous nitrite.

(Summary) This study was an examination of the catalyst deactivation of a silica-supported bismuth-molybdenum complex oxide, and that of catalysts used in the absence of bismuth, for the oxidative dehydrogenation of 1-butene. Due to the detection of deactivation, the molar ratio of 1-butene against oxygen in the reactant gas was adjusted to a ratio similar to that used in industrial processes where reaction temperatures average 100 K higher. Regardless of the presence or absence of bismuth in the catalysts, the conversion of 1-butene was decreased by 6 h on-stream. Both the progress of the coking from the inlet to the outlet of the catalyst and the reduction of molybdenum in the catalysts directly contributed to the deactivation. X-ray photoelectron spectrometry revealed that a greater reduction of molybdenum in the near-surface region and a smaller partial pressure of oxygen (P(O2)) in the reactant gas, although the molybdenum on the surface was not reduced at all. This indicated that the lattice oxygen was pumped from the near-surface region to the surface during the reaction and the oxygen-poor conditions of the near-surface region both in the gas and catalyst phases were formed at a smaller P(O2), which resulted in the enhancements of both the reduction of molybdenum and that of coking. Based on the thermogravimetric analysis, the silica-supported bismuth-molybdenum complex oxide used at P(O2) = 4.1 kPa (color of the catalyst = black) was increased in weight while that used at P(O2) = 16.4 kPa (color of the catalyst = gray) showed a weight decrease, which indicated that the weight decrease caused by the reduction in molybdenum in the near-surface region used at 4.1 kPa was greater than the weight increase from the coking. It was concluded that the reduction in molybdenum followed by the coking on the catalyst surface were the main factors in the catalyst deactivation.

(Summary) The catalytic activities of calcium hydroxyapatite (HAp) and β-type tricalcium phosphate (β-TCP) were examined for their use in the oxidative dehydrogenation (ODH) of isobutane. β-TCP was catalytically inactive for the ODH of isobutane, but stoichiometric HAp returned a high isobutene yield (5.6%). The isobutane conversion and isobutene selectivity of HAp depended on the atomic ratio of Ca/P. HAp with a Ca/P = 1.67 showed the highest levels for both isobutene selectivity and isobutene yield from among HAp catalysts with different Ca/P ratios. Based on a characterization of the acidic-basic properties, it was evident that these acidic-basic properties affect the catalytic performance of HAp, and that its basicity is necessary for high catalytic activity. To improve the catalytic activities of calcium phosphates, they were impregnated with Cr. Despite a much lower surface area for β-TCP, Cr-impregnated β-TCP showed a higher isobutene yield (up to 8.4%) than that of Cr-impregnated HAp. The results of the XPS measurement showed that the Cr3+ species on calcium phosphates, together with the basicity, worked as active sites in the ODH of isobutane.

(Summary) Enhancement of the thermal stability of a catalyst is an efficient way to improve the catalytic activity of a catalytic reaction performed at high temperature. In this study, cerium oxide (ceria, CeO¬2) with a high thermal stability was synthesized by controlling the agglomeration of the primary particles via the thermal hydrolysis of ceric nitrate, accompanied by testing for the catalytic combustion of methane (CH4). The specific surface area of this material after calcination at 1,173 K for 5 h was 50 m2/g, which was much higher than that of the two references materials (ceria made via precipitation of cerous nitrate using aqueous ammonia at 4.1 m2/g, and the Japan reference catalyst JRC-CEO-1 at 1.4 m2/g). The ceria made via thermal hydrolysis showed high crystallinity and a much higher pore volume, which resulted in excellent thermal resistance. For O2 conversion in ceria, catalyzed CH4 combustion at 923 K, the ceria created in this study demonstrated higher activity than that for either reference. The high CH4 combustion performance was due to the high specific surface area and to a superior oxygen storage capacity (OSC) even after a combustion test.

(Summary) Morphological control can be used to improve the catalytic activity of cerium oxide (ceria, CeO2). For this study, ceria with a high specific surface area was synthesized via the hydrothermal reac-tion of ceric nitrate and was tested on the catalytic conversion of ethanol to ethylene. For a refer-ence, ceria was also synthesized via a precipitation reaction of cerous nitrate using aqueous am-monia. The Japan reference catalyst, JRC-CEO-1 also served as a reference. The specific surface area of the hydrothermally synthesized ceria was as high as that of JRC-CEO-1, but was much higher than that of either of the references after calcination at 873 K. Thermo-gravimetric analysis and IR spectroscopy revealed that the cerias made by hydrothermal and precipitation reactions consisted of high-purity CeO2, while the JRC-CEO-1 contained 1.5% decomposable functional groups (OH-, CO32-). For both ethanol conversion and ethylene selectivity in a catalytic dehydration reaction of ethanol, the activity of the hydrothermally developed ceria was higher than that for either of the references. The reaction pathway for the dehydration reaction of ethanol over ceria showed that the specific surface area and the basicity of the Lewis basic site of the ceria were specific influential properties. The high catalytic activity of the hydrothermally synthesized ceria derived from its high specific surface area and high-purity CeO2.

(Summary) Mesoporous silicas have shown promise as materials for solid catalysts or catalyst supports due to their unique characteristics. Metal-doped mesoporous silicas are known to be catalytically active in the oxidative dehydrogenation (ODH) of isobutane. However, heavy-metal-free mesoporous silicas have not been studied closely for their use as catalysts. In the present study, MCM-41 (#41 Mobil composition of matter) was acid-treated to enhance its catalytic activity, although pure MCM-41 was confirmed as catalytically inactive for the ODH of isobutane (isobutene yield = 0.9%). The pH of a slurry of as-synthesized MCM-41 was changed during acid treatment. A pH adjustment to 6.5 resulted in great improvement in catalytic activity (isobutene yield = 6.1%), but a pH adjustment to 4.5 resulted in insufficient improvement (isobutene yield = 4.5%). It was confirmed via XRD and N2 adsorption-desorption measurement that the pH adjustment to 4.5 degraded the ordered structure of MCM-41. This degradation would be a crucial factor that would render acid treatment less effective. In addition to the acid treatment, Al doping to MCM-41 was conducted. Al doping also greatly enhanced the acidity and catalytic activity of MCM-41.

(Summary) To recover phosphorus from composted chicken manure, a batch method with aqueous HNO3, HCl and H2SO4 was used to examine the elution behavior of the aqueous calcium and phosphate contained in the manure. Since the main components in manure are Ca2+ and K+ along with PO43- and those ions can be dissolved using an acidic eluate, it was expected that most of the aqueous Ca2+, K+ and PO43- could be obtained via the elution. Therefore, it seemed plausible that the removal of the aqueous K+ obtained by the elution of composted chicken manure would result in the formation of calcium phosphates. If calcium phosphates are formed, they can be used for phosphate rock, which also consists of various calcium phosphates. When using 0.1 mol/L HNO3, HCl or H2SO4, the elution behavior of the PO43- was not dependent on the acids. However, 0.1 mol/L H2SO4 was not sufficient for the elution of Ca2+, probably due to the precipitation of the calcium sulfate. The eluted amount of K+ using 0.1 mol/L HNO3 was lower than that using 0.1 mol/L of either HCl or H2SO4. Since the poor elution of K+ should enrich the concentrations of Ca2+ and PO43- in the acidic aqueous solution after the elution, it was suggested that aqueous HNO3 would be suitable as an eluate in the present system. After the elution of the composted chicken manure, when 0.1 mol/L HNO3 was used to adjust the solution pH of the acidic aqueous solution to greater than 6, Ca2+ and PO43- were precipitated, but K+ was not. The precipitation was calcium hydroxyapatite, one of the typical components of phosphate rock, which showed that composted chicken manure could be replaced phosphate rock as a new source of phosphorus.

(Summary) MCM-41 (#41 Mobil Composition of Matter) is a favorable material for heterogeneous reactions because of its unique porous structure. However, the catalytic activity of MCM-41 for the oxidative dehydrogenation (ODH) of isobutane to isobutene is known to be quite low. In the present study, a metal-doping method was employed to improve this catalytic activity. Doping of Cr, Co, Ni, or Mo into MCM-41 resulted in a great improvement in the catalytic activity. Since chromium-doped MCM-41 (Cr-MCM-41) showed the greatest catalytic activity among these catalysts, its redox property was further analyzed via XPS, XAFS and H2-TPR techniques. The XPS spectrum of Cr-MCM-41 suggested that it has Cr3+ and Cr6+ species on its surface. Also, a pre-edge peak due to Cr6+ species was confirmed in the XANES spectrum of Cr-MCM-41. In H2-TPR measurement, Cr-MCM-41 was more reducible than crystalline Cr2O3, which showed low catalytic activity for the ODH of isobutane. The reducible Cr6+ species on Cr-MCM-41 contributed to an improvement in the catalytic activity of MCM-41.

(Summary) Three kinds of ZSM-5 zeolites (SiO2/Al2O3=23.8 (Na-form), 39.0 (NH4-form) and 193(NH4-form)) were alkali-treated, and the changes in structural and water adsorptive properties were investigated. With the alkali treatment, the MFI structure was kept; a siliceous species was selectively dissolved from the framework of a zeolite, and the mesopores were created in the zeolites. At the same time, NH4-form ZSM-5 zeolites (SiO2/Al2O3=39.0 and 193) were ion-exchanged to form Na in an aqueous solution of NaOH. In particular, for ZSM-5 (SiO2/Al2O3=23.8), the water adsorption property was changed with the alkali treatment. The difference in the amount of adsorbed water on the zeolite between 30℃ (adsorption temperature) and 100℃(desorption temperature) was increased by the treatment. The desorption temperature of water adsorbed at the stronger site was decreased from 106℃ to 72℃ with the alkali treatment. These results indicate that the introduction of mesopores in ZSM-5 contributed to the enhanced water adsorption properties.

(Summary) The template ion exchange of chromium cations into FSM-16 (#16 Folded Sheets Mesoporous Materials) for 247 h resulted in a 2.89 wt% incorporation of those cations into the FSM-16, although only a 0.3 wt% incorporation had previously been reported. The XRD pattern of the resultant solid (Cr-FSM-16) showed that the hexagonal structure characteristic of FSM-16 remained after the 2.89 wt% incorporation of chromium cations. XPS could be used to detect the Cr3+ and Cr6+ species on the surface of Cr-FSM-16. A pre-edge peak that was due to a tetrahedrally coordinated Cr6+ species was confirmed in the XANES spectrum of the Cr-FSM-16, which showed that the coordination state around some Cr species was similar to that around the Si species in FSM-16. With the increase in the amount of chromium cations in FSM-16, its catalytic activity and stability during the oxidative dehydrogenation of isobutane were evidently improved.

(Summary) In our previous paper, we showed how the catalytic conversion of 1,2-propandiol to propanal using FSM-16 (#16 Folded Sheets of Mesoporous materials) when molded by wet treatment proceeded more favorably than when using FSM-16 molded by pressurization, while no comparison using other typical acidic catalysts and no examination of the acidic properties of FSM-16 was carried out. In the present study, the conversion using FSM-16 molded by wet-treatment and pressurization was compared with the use of typical acidic catalysts such as SiW12O40/SiO2 and MCM-41 (#41 of Mobil Composition of Matter) together with amorphous SiO2. Among these catalysts, FSM-16 molded by wet treatment showed the most suitable catalytic activity. In order to examine the effect of the molding procedure for FSM-16 on its structural and acidic properties, FSM-16 molded by both methods was examined using NH3-TPD, in-situ FT-IR using NH3 as a probe molecule and Hammett indicators together with XRD and TEM. According to Zaitsev's rule, the present conversion should afford acetone rather than propanal, which indicates that it would proceed via hydro-cracking. Therefore the conversion of 1,2-propandiol using FSM-16 was also examined in the presence and absence of hydrogen. Furthermore the hydrations of 1- and 2-propanol when using FMS-16 were also examined. Based on the results obtained from this investigation, it was concluded that the conversion using a more acidic FSM-16 molded by wet treatment proceeded through dehydration rather than through hydro-cracking.

It was found that the lumen of the abaca fibers completely collapsed after 10 and 15 wt% NaOH treatment, due to swelling of the fibers. The fibers also became twisted after these alkali treatments. It was found that cellulose I in abaca fibers was partially transformed to cellulose II after 15 wt% NaOH treatment, as evidenced by XRD measurements. FT-IR analysis indicated that the alkali treatment led to a gradual removal of binding materials; such as hemicelluloses and lignin, from the abaca fibers, resulting in the separation of abaca fiber bundles into individual elementary fibers. The tensile strength of alkali-treated abaca fibers did not vary with alkali concentration. The Young's modulus of the abaca fibers treated with 5 wt% NaOH solution increased by 41%, whereas those treated with 10 and 15 wt% NaOH solution decreased by 24 and 29%, respectively. A non-linear behavior was observed in the stress strain curves of the abaca fibers after 10 and 15 wt% alkali treatment, which could be attributable to the twisting of the fibers.

(Summary) rescence tubes (bag-powder), the batch method with aqueous HNO3 was used to examine the elution behavior of aqueous phosphate contained in the bag-powder. The main components of the bag-powder included Ca2+, PO43- and Y3+ along with Si4+, Sr2+ and lanthanide cations such as La3+ and Ce4+. Therefore, it seemed possible that, with the selective dissolution of Ca2+ and PO43- from the bag-powder, those lanthanide cations in the residue could be enriched. With the batch method, most of the phosphate in the bag-powder was dissolved within 0.2 min using 1.0 mol/L HNO3. The dissolution behavior of calcium cation was similar to that of the phosphate. In contrast, the dissolution of yttrium, the content of which was the highest among the lanthanide cations in the bag-powder, was increased with the dissolution times, reaching complete dissolution after 24 h. The Sr2+, La3+ and Si4+ in the bag-powder, however, did not dissolve under the same conditions. Although Ca2+, PO43- and Y3+ were the main components in the nitric acid extract, Y3+ was separated as YPO4 at pH = 4.0, while Ca2+ and PO43- were separated as calcium phosphates at pH= 7.0. These results revealed that the separation of calcium phosphates, YPO4 and some residue was possible, and resulted in the enrichment of lanthanide cations along with the recovery of phosphorus from the bag-powder. Using the present technique, 91% of the P in the bag-powder was recovered.

(Summary) Although previous researchers have found that FSM-16 (#16 Folded Sheet Mesoporous material) doped with chromium and related Cr-doped silica catalysts has shown great activity for the oxidative dehydrogenation of isobutane to isobutene, information on the nature of these catalysts is insufficient. For this study, three types of Cr-doped silica catalysts were prepared by applying the template ion exchange method. CrOx/FSM-16 and CrOx/SiO2 were used as references. These catalysts were used for oxidative dehydrogenation, which was then characterized via various techniques. The most active catalyst was Cr-doped silica, which did not have the hexagonal structure that is characteristic of mesoporous FSM-16. Various characterizations showed that the catalytic activity of the Cr-species, stemmed from a weak acidic nature and a redox nature that originated from the combination of silicate and a Cr cation, as opposed to the hexagonal structure and strong acidic nature of FSM-16.

(Summary) A method for the recovery and enrichment of the phosphate from dephosphorization slag was examined. First, the elution of aqueous phosphate from dephosphorization slag using aqueous HNO3 was examined using both the batch and flow methods. With the batch method, 82% of the dephosphorization slag could be dissolved within 30 min using 1.0 mol/L HNO3, indicating that the batch method could be used for mass processing to extract phosphorus in the bulk phase, but all components contained in the slag were unselectively dissolved. In contrast, by using 0.05 mol/L HNO3 via the flow method, 22% of the slag was dissolved for 100 min giving a more selective dissolution of phosphate from the slag compared with the batch method, which indicated that this method would be incompatible with mass processing for the purpose of extracting phosphorus in the bulk phase. In order to remove the Fe-species in the aqueous solution obtained by the batch method using 1.0 mol/L HNO3, which has been referred to as the ``slag solution,'' it was necessary to add calcium hydroxyapatite (CaHAp) to the slag solution. The optimal conditions for the removal of Fe-species using CaHAp were observed at a solution pH of ca. 1.5, which resulted in 100% removal of the Fe-species after 4 h. When the pH of the slag solution was adjusted to 7.0 after removing the Fe species, a pale pink solid sample was precipitated. The amounts of phosphate in the slag solution and in the pink solid were 3.5 and 42.0 mol%, respectively, indicating that the treatment suggested in the present study could be used for the recovery and enrichment of phosphate, that is, phosphorous, from dephosphorization slag.

(Summary) The steam reforming of bio-ethanol has been carried out to compare with reagent ethanol using a palladium membrane at several reaction conditions (673 or 873 K, ΔP=0.10 MPa and steam-to-carbon ratio (S/C)=4-10). The raw material of these experiments was surplus bio-ethanol, which is one of the by-products in fermentation with sulfuring process in cornstarch production. As a result, the amount of total H2 formation for bio-ethanol was comparable to that obtained with reagent ethanol under the same conditions. However, for bio-ethanol, the values of hydrogen permeate flow and hydrogen purity were smaller than that of reagent ethanol. In contrast, the amount of CO formed from bio-ethanol was greater than that from reagent ethanol. It is considered that carbon, which has a negative influence on the hydrogen-permeability of the palladium membrane, was produced from CO. The amount of CO was significantly decreased by lowering the temperature from 873 to 673 K. Moreover, CO was also decreased by increasing S/C and was not detected over S/C of 8. However, the amount of total hydrogen production and hydrogen permeate flow decreased by increasing the S/C ratio. Therefore, the best condition for hydrogen production from bio-ethanol using the palladium membrane reactor was at 673 K and S/C=8.

(Summary) The oxidative dehydrogenation of isobutane to isobutene was examined for use in the preparation of FSM-16 and related compounds doped by chromium with expectations that a yield of isobutene of greater than 8% could be achieved. The activity depended on the molding procedure of the catalyst and the doping method of the chromium species. In the present study, 8.8 and 8.3% of the yield of isobutene were obtained at 0.75 and 6 h on-stream for the catalyst (Cr-loading; 6.2 wt.%) molded using wet treatment but not pressurization treatment, in which the chromium species were directly added into the aqueous solution containing raw FSM-16 (hydrated sodium silicate powder) at an initial stage of the catalyst preparation. The structure information was based on XRD, the specific surface area was determined using a conventional BET nitrogen adsorption and the loading of chromium was estimated using ICP. All those parameters combined with the molding method indicated that the catalytic activity was more influenced by the loading of chromium into bulk but not on surface of the catalyst rather than by the hexagonal structure of FSM-16 and the surface area.

(Summary) The catalytic conversion of 1,2-propandiol to propanal is examined using FSM-16 particles (0.85-1.75 mm) molded by wet-treatment and pressurization. When FSM-16 was molded with 0.6 g of pressurization and supplied to the catalytic conversion of 1,2-propandiol at 673 K, this system resulted in a 94.8% conversion of 1,2-propandiol and 90.5% selectivity to propanal at 0.25 h on-stream, which was the maximum amount of activity. However, at 4.50 h on-stream, the activity was decreased extremely to deactivation 19.9% conversion of 1,2-propandiol and 84.7% selectivity to propanal. In contrast, when FSM-16 molded with wettreatment (0.15 g) was used for the conversion at 573 K, activity was greatly increased and stable 98.6% conversion of 1,2-propandiol and 56.2% selectivity to propanal at 0.25 h on-stream followed by 91.9% and 52.5%, respectively, at 4.50 h on-stream. The hexagonal structure of FSM-16 was suggested to have contributed to the suitable conversion of 1,2-propandiol to propanal.

(Summary) The optimization of the oxidative esterification of propionaldehyde to methyl propionate using a supported palladium catalyst in methanol under heavy-metal-free and pressurized-oxygen conditions, which we recently reported in a previous paper, were carried out together with a study of the reaction route, the nature of the catalytic active sites, and the effect of the support. In our previous paper, we reported significantly improved activity for oxidative esterification using commercially available 5%Pd/Al2O3 at 1.5 MPa of O2 gas and 333 K and emphasized that the doping of 5%Pd/Al2O3 with lead was not needed for the reaction system, but we could not improve the activity that was reported when using 5%Pd/ -Al2O3 doped with 5% Pb (a 93.2% conversion of propionaldehyde, 76.8% selectivity for methyl propionate and a 71.6% yield of methyl propionate) at 0.3 MPa of O2 gas and 353 K, as reported by another laboratory. In the present study, however, we exceeded those values and obtained a 98.3% conversion of propionaldehyde, 75.3% selectivity for methyl propionate and a 74.0% yield of methyl propionate using 5%Pd/ -Al2O3 undoped with Pb at 1.5 MPa of O2 gas and 333 K. It should be noted that, in the preparation of the present 5%Pd/ -Al2O3, Pd was doped onto Al2O3 that had been previously treated with aqueous NaOH. Another active alumina support, -Al2O3, prepared from boehmite, afforded activity that was substantially lower than that of -Al2O3 and depended on the calcination temperature of boehmite to -Al2O3. When using various concentrations of CH3OH in the aqueous reaction solution, the oxidative esterification proceeded through the formation of propionic acid. To determine why Al2O3 support afforded better activity than active carbon support, Pd/Al2O3 and Pd/C catalysts were examined by XAFS (X-ray absorption fine structure). XAFS revealed that Pd on Al2O3 shows a better redox nature than Pd on C, which resulted in activity on Pd/Al2O3 that was better than that on Pd/C.

(Summary) In this paper, we examined the influence of particle size on anti-adhesion effect of a surface polished steel plate. SiO2 spherical powders and stainless steel plates with seven kinds of surface roughness were used for the investigation. The adhesion tests of SiO2 powders to the polished stainless steel plates were performed using powders of nominal size 9 and 13μm. In the case of 13μm powder, the obvious adhesion and deposition of powder was not observed for all steel surface conditions. However, strong adhesion of particles and thin deposition layers were observed for 9μm powder, being independent of surface roughness of the steel plates. The size of adhered particles on the steel plate were measured by SEM observations in order to examine the adhesion mechanism of SiO2 particle to the polished stainless plate substrate. As a result, adhesion of 3-5 μm particles to the steel surface was largely independent of surface roughness. The adhesion of 3-5 μm particles can be avoided by mixing of small particles of 0.5μm powder into 9μm powder.

(Summary) Plating a Pd membrane on the outer surface of a porous stainless steel (PSS) tube facilitates rapid H2 permeation with an absolute selectivity; the permeation is based on the solution-diffusion transport mechanism. Reforming of carbon hydride is a well-known method of manufacturing H2. CH4 dry reforming is performed in a membrane reactor using a thin Pd membrane. In this reaction, chemisorbed CO2 is known to affect H2 permeation behavior. The effect on H2 permeation and membrane stability were investigated by performing a permeation test and by XPS. After H2 was permeated through the Pd membrane, CO2 was flowed over the membrane for 1 h, and H2 was once again permeated through the membrane. In the experiment, the temperatures were 623, 723, and 823 K, the differential pressure was 0.1 MPa, and the feed rate was 10 mL/min. CO2 was replaced by He and the experiment was performed under the same conditions. After the second H2 permeation, the H2 flux increased with the time and attained its original value. The time required to attain the original value was dependent on the gas and the temperature. In the case of the He flow, the time required was only 5 min and was independent of the temperature. On the other hands, in the case of the CO2 flow, the required times were 10 min and 25 min at 623 K and 723 K or 823 K, respectively. After the CO2 flow, the XPS spectra of the surface of the Pd membrane were measured. The spectra showed that PdO was formed on the Pd membrane by oxidation of the Pd surface. The PdO was formed by chemisorbed CO2, and the H2 permeability was degraded by PdO; however, PdO was easily reduced to Pd by the H2 flow. When the experiment involving CH4 dry reforming was performed in the Pd membrane reactor with conventional Pt-based catalysts and a sweep gas for 12 h at 873 K, the H2 flux, H2 selectivity, and H2 recovery were ca. 6 mL/min, 98% (calculated by excluding the sweep gas), and 80%, respectively.

(Summary) In this paper, we examined the relationship between surface roughness and particle adhesion behavior by a proposed experiment. Five kinds of SiO_2 spherical powders (powder diameter: 0.2, 0.5, 1.0, 1.5 and 2.0μm) and stainless steel plates with seven kinds of surface roughness were used for the invetigation. The effect of humidity, electrostatic force and van der Waals force on the particle-steel adhesion behavior was also examined. The experimental results showed that van der Waals force was relatively important to the adhesion behavior compared with two other effects. The adhesion ratios of SiO_2 powders to polished stainless steel plates were measured. The adhesion ratios depend on the surface roughness and the particle diameters. The adhered particles on the steel plate were observed by SEM in order to examine the adhesion mechanism of SiO_2 particle on the polished stainless plate substrate. As the result, 0.4-1.0μm particles were easy to adhere independent of surface roughness and nominal powder diameter. The result indicates that adhesion behavior of powder depends on the adhesion force of 0.4-1.0μm particles that are changed by the surface roughness of the steel plate.

(Summary) Activated carbons were prepared from bamboo by chemical activation with K2CO3 or physical activation with CO2. The structural and surface chemical characteristics of the activated carbons were determined by N2 adsorption-desorption and Boehm titration, respectively. The water vapor adsorption properties of the activated carbons with various pore structures (preparation conditions) were examined. The relationship between water vapor adsorption capacity and pore properties, and the humidity control capacity of the prepared activated carbons are also discussed. The water adsorption isotherms show a region of rapidly increasing uptake of water vapor, and the relative humidity corresponding to those regions was different according to the preparation conditions, especially activation temperature. Water vapor adsorption capacity was improved with larger pore volume and surface area, but the humidity control capacity in a certain specific humidity region differed greatly according to the relative humidity corresponding to the steeply rising regions of the isotherms. In the typical operating conditions of an adsorption heat pump, RH 10-35%, the bamboo-sourced activated carbon that was prepared at 873K by potassium carbonate activation with impregnation ratio 1.0 had the highest humidity control capacity.

(Summary) The effects of Ni addition on the catalytic activity of MFI zeolite catalysts were examined with the ethanol conversion reaction under high space velocity conditions, using pure ethanol, ethanol diluted with water, and bioethanol produced from corn, and the effects of impurities on deactivation were evaluated. Addition of Ni to MFI zeolite strongly suppressed the formation of aromatic compounds, and greatly improved the selectivities for C3 and C4 olefins from pure ethanol, but decreased the selectivities for C3 and C4 olefins, and slightly reduced the suppression effect of the Ni site for aromatic formation from bioethanol. The yields of C3 and C4 olefins decreased with time-on-stream despite the presence of the Ni sites. XPS analysis of the catalysts after reaction at 673 K showed presence of oxidized carbon species, indicating the deposit of the impurity from the bioethanol. In addition, the electronic state of Ni after the reaction of bioethanol was also different to that after the reaction of reagent ethanol. XPS analysis showed the formation of Ni2O3 species or nickel sulfate during the reaction of bioethanol, which caused catalyst deactivation. In the reaction at 773 K, a large amount of filament carbon was deposited on the catalyst surface. These factors caused significant decreases in the formation of C3 and C4 olefins in the conversion of bioethanol.

(Summary) A bench-scale annular-type packed-bed photocatalytic reactor with TiO2-coated glass beads as the photocatalyst was designed; the performance of the reactor was evaluated by using it for the photocatalytic decomposition of indigo carmine (IC) dissolved in water. The reactor was operated in a recirculation batch mode, and the dye solution in the reservoir was recirculated through the photocatalyst bed in the annular space of the reactor. The concentration of the dye in the reservoir decreased gradually with an increase in the operation time. The time course of the change in the IC concentration was calculated numerically by assuming first-order kinetics, and the overall rate constant of photocatalytic decomposition was determined by fitting the calculated time course to the experimental value obtained for various treatment times. The overall decomposition rate constants decreased with an increase in the initial concentration of the IC solution. The rate-controlling step in the photocatalytic decomposition was the mass transfer of IC from the bulk of the solution to the catalyst surface when the flow rate was less than 1 dm3/min; however, when the flow rate exceeded the transition flow rate, the reaction occurring at the catalyst surface was the rate-controlling step.

(Summary) Gas adsorption onto optical surfaces equipped in satellites is one of the causes of signal degradation occurred in orbit and water is one of the most potent ad-molecules. To estimate the degradation caused by water adsorption onto optical glass surface, the transmittance measurements were carried out in UV-VIS (200--800nm) and IR (1.7--20μm) wavelength ranges. Five kinds of glasses, SiO2, BK7, Al2O3, CaF2, and ZnSe, which are typically used for satellite optics, were selected as glass samples. In IR wavelength range, a local absorption feature was appeared at λ=3.1μm when a glass temperature was below 200K. The phase change of adsorbed water from vapor to solid may account for the newly appeared absorption. In UV-VIS region, there was no local absorption feature but broad transmittance decrease. BK7 and ZnSe, which are hydrophobic, showed little transmittance decrease and it was hard to find the wavelength dependence for their transmittance spectra. On the other hand, the transmittance spectra of hydrophilic glasses, SiO2, Al2O3, and CaF2, showed wavelength dependence and had the local minimal value. From our computation, it is found that the growth of ice grains on a glass surface makes it possible to reproduct the spectral transmittance degradation detected for hydrophilic glasses.

(Summary) Naproxen (NP) and flurpibrofen (FB) as non-steroidal anti-inflammatory drugs (NSAIDs) of 2-arylpropionic acid derivatives have been used as host organic drugs to be intercalated into layered double hydroxide (LDH) applying reconstruction and co-precipitation techniques. The obtained NP LDH and FB LDH nanocomposites were characterized by X-ray powder diffraction, infrared and thermogravimetric analyses. From drug loading, thermal analysis and X-ray measurements we can decide that coprecipitaion technique is better than reconstruction technique to obtain intercalated monophase nanocomposites. In acidic medium LDH dissolved and the intercalated drug starts to release in a molecular form which is suitable for adsorption. The drug solubility has been investigated before and after intercalation. It has been found that LDH improves the drug solubility and its dissolution rate.

(Summary) The conversion of bio-ethanol (ethanol: 77.4%, water: 19.6% and trace) derived from corn into hydrocarbons over HZSM-5 zeolites was studied. The reaction behaviors for formation of gaseous olefins and aromatics at WHSV=26 h-1 at 573 773 K were discussed by comparing with those of pure ethanol and 80% ethanol aqueous solution. The main products in the bio-ethanol conversion were ethylene or diethyl ether, and C3 C5 hydrocarbons and aromatics were also produced. The selectivity of olefins formation in C3 C4 hydrocarbons was depends on the reaction temperature. The yields of C3 C4 olefins increase with the rise of reaction temperature. The formation of them from bio-ethanol needs higher temperature than that from ethanol, and the decline of activity for bio-ethanol conversion was observed faster than that for a pure ethanol and an ethanol/water solution. The reason was explained by the strong acid site of HZSM-5 was poisoned by impurities in bio-ethanol such as sulfur. The content of aromatics was the largest at 648 K, but it decreased at 673 K. The order of amounts of aromatics produced were from pure ethanol>bio-ethanol>ethanol/water solution. The coexistence of water depressed the amount of aromatics, but the active sites changed by impurities in bio-ethanol promoted the formation of aromatics.

(Summary) Yellowish S-containing TiO2 (S-TiO2) powders were prepared by calcination of a mixture of titanium(III) chloride and ammonium thiocyanate solutions. Three kinds of S-TiO2 were prepared by varying the concentration of ammonium thiocyanate (0.5, 1 or 13 M). X-ray photoelectron spectroscopy spectra of the S-TiO2 showed that sulfur atoms existed on the surface of TiO2 powders. But the peaks assigned to S disappeared after Ar+ etching, which means that these atoms were not doped in the bulk of the TiO2 powders. While UV-visible absorption spectra of S-TiO2 showed that the absorption edges of these photocatalysts were seen to shift to a longer wavelength (lower band gap energy) than those of undoped rutile TiO2 prepared and commercial anatase type TiO2 (ST-01). The S-TiO2 (1 M) exhibited higher photocatalytic activity than ST-01 for degradation of methylene blue in aqueous solution under visible light irradiation (lambda > 400 nm). It was also confirmed by IR spectroscopy that acetaldehyde in oxygen under visible light irradiation (lambda > 400 nm) was decomposed to acetic acid by the S-TiO2 and ST-01 at the first decomposition step.

(Summary) Three kinds of catalysts of goethites supported on γ-Al2O3 (Fe/γ-Al2O3), SiO2-Al2O3 (Fe/SiO2-Al2O3) and SiO2 (Fe/SiO2) were investigated in terms of the catalytic activity of methane oxidation. The specific surface areas of these catalysts were larger in common than the area of goethite with no supports. The Fe/γ-Al2O3 catalyst has the highest performance in the low-temperature activity of methane oxidation which started at 623 K and completed at 923 K. When the Fe-content in Fe/γ-Al2O3 was increased, the formation of goethite was observed by the X-ray analyses and the activity of this catalyst increased up to 6 mol%. After the catalytic methane oxidation at 823 K, it was observed that goethite in Fe/γ-Al2O3 transformed to hematite which has been known as an active iron oxide in methane oxidation. The activity of Fe/γ-Al2O3 was enhanced by the addition of sodium up to the Na-content of 5 mol% although it descended above the content due to the decrease of the specific surface area of the catalyst.

(Summary) To modify the adsorption characteristics of the mesoporous silica FSM-16, Al-incorporated FSM-16 (Al-FSM-16) and trimethylsilylated FSM-16 (TMS-FSM-16) were prepared. The pore structureand the adsorption characteristics of these modified mesoporous materials were examined by usingprobe molecules of N2 and CO<sub>2</sub>. BET surface area of Al-FSM-16 was reduced to 470 m<sup>2</sup>·g<sup>-1</sup>, about one-half of the surface area of FSM-16. However, the separation factor for CO2 from CO<sub>2</sub>-N<sub>2</sub> gas mixtures (CO<sub>2</sub>/N<sub>2</sub>=20.1/79.9) on Al-FSM-16 was higher than on FSM-16 in the total pressure range from 0.2 to 0.3 MPa. This implies that CO<sub>2</sub> is adsorbed selectively to Na+, which is present to compensate for thenegative charge generated by incorporating Al in the framework of the mesoporous silicas. By trimethyl-silylation of FSM-16, 82% of the surface area was covered with trimethylsilyl (TMS) groups, and thepore size decreased to 2.3 nm from the 2.8 nm of FSM-16. Much less CO2 was adsorbed on TMS-FSM-16 than that on FSM-16, possibly due to the smaller amount of free SiOH groups of TMS-FSM-16.

(Summary) Adsorption characteristics of alkali metal ion-exchanged ZSM-5 zeolites, M-ZSM-5 (M=Li, Na, K, Rb, and Cs), for CO(2)/N(2) mixtures were investigated by a column method and IR study. It was shown that CO(2) was adsorbed from CO(2)/N(2) mixtures on M-ZSM-5 zeolites by two types of adsorbtion at temperatures below 333 K. One was a weak adsorption due to interaction with the wall of ZSM-5, and the other was a strong adsorption caused by interactions with the cation of ZSM-5. IR-spectra of gases adsorbed at various temperatures revealed that the CO(2) were strongly adsorbed on M-ZSM-5 in several ways, which seemed to be caused by different adsorption sites. At temperatures above 373 K, almost all CO(2) adsorbed were on cation sites, while N(2) coadsorbed with CO(2) was shown to interact with the wall of ZSM-5 under all experimental conditions.

(Summary) To prepare 1,3-butadiene, one of versatile chemicals, from 1-butene, one of the main components in liquefied petroleum gas (LPG), the oxidative dehydrogenation of 1-butene on -Bi2Mo3O12 doped with cerium was examined. Regardless to the doped amount of cerium, the conversion of 1-butene was constant while the selectivity to 1,3-butadiene decreased with the doped amount of cerium, while the selectivities to 2-butenes, CO and CO2 increased. It is concluded that the introduction of cerium into -Bi2Mo3O12 resulted in the enhancement of the greater acidic nature of the catalyst while the mild acidic nature of the catalyst seems to be suitable for the effective synthesis of 1,3-butadiene from 1-butene via the oxidative dehydrogenation.

(Summary) In order to obtain calcium phosphates - a phosphate rock equivalent - from the incineration ash of chicken manure, which is obtained from power generation systems that use the manure for fuel, incineration ash was treated with an aqueous solution of nitric acid to elute phosphorus. By using 0.3 M of HNO3, most of the phosphorus could be eluted from 1.0 g of ash within 0.1 h. Compared with the composted chicken manure that was previously examined in our laboratory, the concentration of HNO3 was increased for this session of elution. Using the incineration ash of chicken manure made it possible to remove inorganic species at a lower boiling or sublimation temperature, and organic species by calcination in the power generation system. Compared with composted chicken manure, the concentrations of phosphorus contained in the incineration ash and the nitric acid extract were higher in the incineration ash. XRD analysis showed that the obtained nitric acid extract could be treated with aqueous NH3 to form a precipitation of poorly-crystallized calcium hydroxyapatite (Ca10(PO4)6(OH)2), which is one of main components in phosphate rock. In order to confirm the formation and purity of calcium phosphate species, the precipitation calcination was conducted at 1,078 K for 5 h. XRD revealed that the calcined solid was tricalcium phosphate, and no contamination was evident. These results reveal that a phosphate rock equivalent could be easily obtained from the incineration ash of chicken manure, which means that approximately 14% of the phosphate rock that is currently being imported into Japan could be replaced by this product.

(Summary) A new approach of improving the drug solubility and permeability is the intercalation into layered double hydroxide (LDH) which is biocompatible and has pharmaceutical applications. Through hydrotalcite, the interlayer counterions can be replaced by organic drugs or polymers applying reconstruction, coprecipitaion processes. In acidic medium the hydrotalcite dissolved releasing the intercalated compounds in a molecular form which is suitable for adsorption. The samples were characterized by X-ray diffraction, FTIR spectroscopy, SEM, specific surface area and in vitro release. The results are discussed with those of other materials e.g. thermosensitive polymer gels.

(Summary) 本研究では，プロピレンと酸素から固体酸触媒を用いて各種化成品原料であるプロピレンオキサイド(PO)を合成について発表する．本研究で取り上げる気相接触部分酸化反応は，従来法と比較すると，環境負荷が小さく簡易なプロセスでPOを合成できる一方で，PO選択率が低いことが問題点となる．触媒の酸特性がPO生成に影響すると考えられたため，ゼオライトを基軸とした固体酸触媒を用いてPO選択率の向上を目的として検討した．さらにメソポーラスシリカであるSBA-15を触媒および担体とすると副生成物の生成が抑えられることについても報告する．

(Summary) イソブタンの酸化脱水素反応について，C3炭化水素の酸化脱水素反応に有効な触媒を用いてもイソブテン収率は2%以下であった．クロムをMCM-41などのメソーポーラスシリカに添加した触媒を用いるとイソブタン収率が8%程度に改善したが，それ以上の改善ができなかった．本発表では，SBA-15に微量のクロムを導入したところ，イソブタン収率が再現良く15%以上を超えることができ，クロムの量が微量なためにクロムの状況が当初不明であったが，XPSやXAFSにより情報が得られる可能性ができたので報告する．
