(Summary) In the present study, we developed a technology for concentrating and recovering phosphorus from slag-like phosphorus-containing unused resources and applied it to slag discharged during the latest steelmaking process, that is, double-slag refining process (DRP). The technology we developed consists of the following four processes: Process (1) is the initial acid elution; Process (2) involves alkali precipitation; Process (3) is the second acid elution; and, Process (4) utilizes ion-exchange. In Process (1), the addition of DPR slag to 0.5 M of a nitric acid solution for 24 min resulted in sufficient phosphorus dissolution. In Process (2), ammonia was added to the dissolved solution, and phosphorus was precipitated with high efficiency. The timing of the addition of ammonia significantly influenced the removal of silicon and iron, which would have been inconvenient to accomplish in subsequent processes. In Process (3), the precipitation obtained in Process (2) was re-dissolved in a nitric acid solution. The dissolution of phosphorus together with other elements progressed sufficiently, and we confirmed that silicon could be completely separated as silica by using high-concentration nitric acid at this stage. The fact that silicon could be removed during Process (3) was an important finding, since silicon could not have been separated in the Process (4). In Process (4), by passing the phosphorus-containing solution obtained in Process (3) through an ion exchange resin, elements other than phosphorus and silicon could be removed, which confirms that the range of applications for this technology could be expanded.

(Summary) Improvement in the dehydrogenations of ethane, propane, and isobutane over alumina-supported nickel oxides have been reported along with the formation of large amounts of carbon deposition with time-on-stream, but catalyst activity is decreased with an additional increase in time-on-stream. This improvement in activity is due to metallic nickel that is highly dispersed over carbon nanotube-like depositions. When this highly dispersed metallic nickel is further covered with carbon deposits, the activity decreases. In this paper, we describe the result of oxygen treatment to regenerate the catalyst. It is generally accepted that oxygen treatment, to remove carbon depositions, results in a less active catalyst due to sintering of the active species. We speculated, however, that sintered nickel oxide could form carbon nanotubes in the proposed system, and that the formation of highly dispersed nickel over the nanotubes would regenerate the catalyst. To prove this hypothesis, the dehydrogenations of ethane, propane, and isobutane were investigated using 18, 15, and 20% nickel oxide supported on γ-alumina, respectively. We confirmed regeneration of the catalytic activity via oxygen treatment during subsequent dehydrogenations.

(Summary) In our previous paper, we reported that the reductive conversion of 2-chloropropene (2-PEN) on -alumina-supported palladium catalysts showed high activity at 348 K. In this catalyst system, however, 2-chloropropane (2-PAN), propylene, and propane were produced non-selectively, which necessitated a separation process when considering actual industrial development. In the present study, an alumina-supported nickel catalyst achieved a highly selective conversion of 2-PEN to propylene. For example, at 473 K, the propylene selectivity reached 95.7% when the conversion of 2-PEN was 15.0% on the catalyst loaded with 10% nickel. However, since propylene yield was only 14.3%, the reaction was examined at 623K. This resulted in a 75.6% conversion of 2-PEN and a 78.6% selectivity to propylene, which accompanied to a sufficient 59.4% yield. The most notable point was that no propane was produced under these conditions. Therefore, there is no need to separate propane and propylene. We concluded that by using nickel as a catalyst, an excessive reduction of propylene to propane could be suppressed.

(Summary) We recently reported an efficient procedure for recovering phosphoric acid from dephosphorization slag. This recovery procedure consists of a combination of the following four processes: (1) A first dissolution process of slag in a nitric acid solution; (2) a precipitation process then adds ammonia to the obtained eluate; (3) a second dissolution process dissolves the precipitation from the nitric acid eluate; and, (4) the final process involves ion exchange in which the obtained eluate is passed through an ion exchange resin. In the present study, this recovery procedure was applied to concentrate and recover phosphorus from sewage-sludge molten slag, which is an unused resource that should be considered a new resource for phosphorus. As a result, our procedure for recovery from dephosphorization slag was viable following two revisions. Initially, the time for the first dissolution process was extended from 0.2 h to 1 h, but 0.2 h proved to be the optimum time for dephosphorization slag. Next, we discovered it was better to perform the filtration one day after adding the ammonia instead of immediately after adding it. The other two processes could be treated under substantially the same conditions as in the case of dephosphorization slag, and high-purity phosphorus was obtained.

(Summary) In the recent study, the dehydrogenation of isobutane to isobutene was accomplished using a NiO/ -Al2O3 catalyst, and significant improvement in the time-on-stream yield of isobutene was accomplished. During the normal catalytic dehydrogenation of alkanes, the catalyst is covered by the carbon deposition that is generated during the reaction, which drastically reduces activity with time-on-stream. Therefore, no examples of the catalytic dehydrogenation of isobutane have yet been reported. This study used either ethane or propane as a source of isobutane to examine whether the activity was improved with time-on-stream. As a result, in the dehydrogenations of both ethane and propane on a NiO/ -Al2O3 catalyst, the catalytic activity decreased with time-on-stream when the supporting amounts of NiO was small. By contrast, when the supporting amount of NiO was large, the catalytic activity improved with time-on-stream. The results using a NiO/ -Al2O3 catalyst with small and large NiO loadings were similar to those of isobutane dehydrogenation and it was confirmed that the dehydrogenation activity was improved with time-on-stream in the catalytic dehydrogenations of ethane, propane, and isobutane using large NiO loadings. Intermediate behavior using a moderate amount of NiO loading, which was not detected in the dehydrogenation of isobutane, was also observed, which resulted in a maximum yield of either ethylene or propylene at 2.0 or 3.25 h on-stream, respectively. We concluded that the reason the catalytic activity did not improve with time-on-stream when using a NiO/ -Al2O3 catalyst was because the supporting amount of NiO was too small. These results show that activity with time-on-stream could also be improved in the dehydrogenations of other alkanes.

(Summary) In the transformation reaction of alkanes to alkenes via catalytic dehydrogenation, it is generally accepted that the so-called catalytic deactivation behavior will occur. This phenomenon causes a drastic reduction in activity with time-on-stream. It is understood that carbon deposition generated during the reaction then covers the surface of the catalyst, and this leads to a drastic decrease in activity. However, contrary to this common wisdom, our laboratory reported that the dehydrogenation of isobutane to isobutene on NiO/γ-Al2O3 within a specific range of NiO loading in the presence of CO2 actually improved the yield of isobutene with time-on-stream. Since few such cases have been reported, in this study, isobutane was dehydrogenated in the presence of CO2 using NiO/α-Al2O3 as the catalyst with 20% NiO loading and improvement was again observed. In order to investigate the cause of the improvement, both NiO/γ-Al2O3 and NiO/α-Al2O3 with 20% NiO loading were examined in detail following the reaction. According to TEM analysis, both catalysts were covered with a large amount of carbon deposition after the reaction, but there was a difference in the types. The carbon deposition on NiO/γ-Al2O3 had a fibrous nature while that on NiO/α-Al2O3 appeared to be a type of nanowire. Raman spectroscopy revealed that the carbonaceous crystal growth properties of two forms differed depending on the support. In particular, a catalytically active species of metallic nickel was formed in a high degree of dispersion in and on the above two forms of carbon deposition during the reaction, and this resulted in high activity even if the catalyst was covered with a carbon deposition.

(Summary) We recently developed a method for efficiently recovering phosphoric acid from dephosphorization slag. The most important processes in this recovery technique involve elution of the dephosphorization slag into an acid solution (acid-elution process) and the addition of an alkali to the acid eluate to form a precipitate (alkali-precipitation process). Ultimately, we settled the use of an aqueous nitric acid solution for the acid-elution step, while an aqueous ammonia solution proved to be the optimal choice to accomplish alkali precipitation. Herein, we describe the procedures used to compare the utility of nitric acid with that of hydrochloric acid, sulfuric acid, and citric acid in the acid-elution process, and describe our comparison of an aqueous sodium hydroxide with that of an aqueous ammonia in the alkali-precipitation process. Finally, we summarize our findings on the acids and alkalis that proved to be suitable for this technology.

(Summary) We previously reported that by adding aqueous ammonia to the nitric acid extract of dephosphorization slag, a solid with enhanced concentrations of calcium and phosphorus, could be recovered. The present study shows that a considerable amount of manganese and iron also remains, however, which creates difficulties in directly reusing the recovered solid. The recovered material was again dissolved in nitric acid and the resultant filtrate was passed through a cation exchange resin that mostly removed various cations from the yield of an aqueous phosphoric acid solution. The recovery of phosphoric acid was confirmed via 31P NMR. Furthermore, when calcium nitrate was added to this aqueous solution, calcium hydroxyapatite, which was converted to calcium phosphate after the calcination at 1073 K. Phosphoric acid, calcium hydroxyapatite, and calcium phosphate are raw materials that are used to produce various industrial products containing phosphorus, and the suggested process greatly improves the technology for recovering phosphorus-containing materials that are mostly used as fertilizer.

(Summary) Allyl chloride is a synthetic intermediate that is used as an alkylating agent for pharmaceuticals, and is commonly synthesized at production sites related organochlorides. Allyl chloride is also the raw material that serves as a cross-linking agent for synthetic resins. In that particular synthesis process, however, the by-product 2-chloropropene (2-PEN) is a problem because it essentially has no practical use. In this study, an effective use for 2-PEN was investi-gated in the syntheses of 2-chloropropane (2-PAN) and propylene, which are precursors for various chemical products. To accomplish this, 2-PEN was hydrogenated on commercially available palladium catalysts such as OleMax 201, Ole-Max 301, OleMax 600, and HyFlex 500. The maximum yield of 2-PAN (10.6%) was detected at 348 K, P(H2) = 13.5 kPa and P(2-PEN) = 8.8 kPa, on OleMax 600 (0.5 g), while the maximum yield of propylene (26.0%) was realized under the same reaction conditions, with the exception of using at P(H2) = 7.9 kPa on HyFlex 500 (0.5 g). The selective formation of propylene such as 8.9, 100, and 8.9% for the conversion of 2-PEN, the selectivity of propylene, and the yield of propylene, respectively, were realized on OleMax201. The selective formation of 2-PAN, however, was not observed on all catalysts. Palladium loading strongly influenced the catalytic activity, but had none on either the specific surface area, or basic and acidic properties.

(Summary) The effect that UV-LED irradiation exerted on a sodium-modified silver catalyst supported on strontium carbonate (Ag-Na/SrCO3) was examined during an epoxidation of propylene to pro-pylene oxide. Based on our previous study, we used Ag(56)-Na(1)/SrCO3 in this study. The num-bers in parentheses refer to the weight percentage of silver and sodium. Although this catalyst system did not contain typical photocatalysts such as titanium oxide or tungsten oxide, UV-LED irradiation of Ag(56)-Na(1)/SrCO3 resulted in an evident improvement in the selectivity and yield of propylene oxide. Such an advantageous effect of UV-LED irradiation could not be dis-cussed based on the bandgap used in photocatalysts, and, therefore, we proposed a mechanism based on the plasmon excitation of silver, which could be accomplished using the irradiation wavelength of UV-LED to produce electrons. Since the lifespan of these electrons is expected to be short, it is difficult to place them into direct contact with the gas phase of oxygen. Once the generated electrons move to SrCO3, however, the lifespan is improved, which could allow suit-able contact with oxygen in the gas phase to form active oxygen. If the oxygen is active for epoxidation as hydrogen peroxide, this could explain the improvement in activity from UV-LED irradiation.

(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.

(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) 抄録メタン水蒸気改質(SMR)反応を0.1∼2.0 wt% Pt/α-Al2O3触媒を用いて10 ppmのジメチルスルフィド(DMS)を含む条件と含まない条件で行った．DMSを含む場合は初期に劣化が生じるが失活には至らなかった．DMSの供給を停止すると活性は完全に元に戻った．DMSを含むガスの場合は1.0∼2.0 wt% Pt/α-Al2O3触媒上のPtはシンタリングして炭素析出を促進した．このシンタリングと炭素生成挙動はSMR反応と無関係であった．一方，Pt担持量が0.1 wt%だと炭素析出は起こらなかった．これらの結果からPt/α-Al2O3触媒上には三つの活性サイトが形成されたと考えた．一つ目はDMSの影響を受けない活性点，二つ目はDMSにより活性を失うがDMSの供給を停止すると完全に再生する活性点，三つ目はSMRの活性点ではなくシンタリングしたPtがメタン分解を促進して炭素を生成する活性点である． (Keyword) Steam methane reforming / Platinum catalyst / Sulfur poisoning / Sintering / Carbon formation / Active site (Tokushima University Institutional Repository) ● Metadata: 114385 (Link to Publication Site) ● Publication site (DOI): 10.1627/jpi.63.89 (Link to Search Site for Scientific Articles) ● CiNii @ National Institute of Informatics (CRID): 1390846609809202432 ● Search Scopus @ Elsevier (DOI): 10.1627/jpi.63.89 (Tokushima University Institutional Repository: 114385, DOI: 10.1627/jpi.63.89, CiNii: 1390846609809202432)

(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) We investigated the durability of Ni/TiO2 catalyst in CO selective methanation reaction. In the reaction test up to 72 h, trace amounts of chlorine component contained in the catalyst gradually decreased. As a result, the progress of the methanation of CO2 increased, leading to a decrease in the reaction selectivity of the methanation of CO required for the catalyst in the title reaction. By contrast, in the early stage of the reaction in which the elimination of chlorine component was small, it was confirmed that the number of active sites of metallic Ni increased, and the CO methanation activity was improved. Furthermore, it was found that the chlorine component in the catalyst was more remarkably removed by the reaction heat under the methanation reaction atmosphere compared to the other atmospheres. Catalyst durability under the conditions simulating a daily start-up and shut-down operation that repeated a cycle of cooling and heating the temperature of the catalyst layer to room temperature was also evaluated. As a result, we revealed that a trace amount of chlorine component was removed by exposure to condensed water, leading to a decrease in the reaction selectivity of the catalyst.

(Summary) We recently reported an efficient procedure for the recovery of phosphoric acid from dephosphorization slag. This recovery procedure consists of a combination of the following four processes: (1) a first dissolution of the slag by suing the nitric acid; (2) a precipitation process by adding ammonia; (3) a second dissolution of the precipitation by using the nitric acid; and (4) a final process involving ion-exchange, where the obtained eluate was passed through an ion-exchange resin. In the present study, sewage sludge molten slag was employed instead of dephosphorization slag. As a result, our procedure for recovery from dephosphorization slag was viable following two revisions in the case of sewage sludge molten slag. Initially, the time for the first dissolution process was extended from 0.2 h to 1 h. Next, we discovered it was better to perform the filtration one day after adding the ammonia instead of immediately after adding it. The other two processes could be treated under substantially the same conditions as in the case of dephosphorization slag, and high-purity phosphorus was obtained from sewage sludge molten slag.

(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.
