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.","ja":"プロピレンのプロピレンオキシドへのエポキシ化に対して炭酸ストロンチウムに担持されたナトリウム修飾銀触媒(Ag-Na/SrCO3)を用いた場合のUV-LED照射も影響を検討した．既報の結果に基づいて，この研究ではAg(56)-Na(1)/SrCO3を使用した．なお，括弧内の数字は，銀とナトリウムの重量パーセントを示す．この触媒には，酸化チタンや酸化タングステンなどの，一般的な光触媒は含まれていないが，Ag(56)-Na(1)/SrCO3触媒にUV-LEDを照射すると，酸化プロピレンの選択性と収率が明らかに向上した．このようなUV-LED照射の加速な効果は，光触媒の議論で汎用されるバンドギャップではできなかったため，UV-LEDの照射波長により発現する銀のプラズモン励起に基づくメカニズムを提案した．UV-LEDを銀のナノ粒子にい照射してプラズモン電子が生成する．これらの電子の寿命は短いと予想されるため，酸素の気相と直接接触させることは困難である．ただし，生成された電子がSrCO3に移動すると，寿命が長くなり，気相中の酸素と適切に接触して活性酸素を形成できるようになる．酸素が過酸化水素のようなエポキシ化に対して有効な活性酸素である場合，本研究で観測されたUV-LED照射による活性の改善を説明できる．"},"publication_date":"2021-03-21","publication_name":{"en":"Catalysts","ja":"Catalysts"},"volume":"11","starting_page":"398","ending_page":"406","languages":["eng"],"referee":true,"identifiers":{"doi":["10.3390/catal11030398"],"issn":["2073-4344"]},"published_paper_type":"scientific_journal"},"priority":"input_data"}

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.

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.","ja":"コンポスト化鶏糞を硝酸水溶液による湿式処理を行い，得られた水溶液をアンモニアでpHを制御すると，リン鉱石の主成分であるリン酸カルシウムを高純度で得ることができ，枯渇資源リンを廃棄物鶏糞から効率よく取得できることが明らかになった．"},"publication_date":"2016-02-20","publication_name":{"en":"Journal of Chemical Engineering of Japan","ja":"Journal of Chemical Engineering of Japan"},"volume":"49","number":"2","starting_page":"224","ending_page":"228","languages":["eng"],"referee":true,"identifiers":{"doi":["10.1252/jcej.15we111"],"issn":["0021-9592"]},"published_paper_type":"scientific_journal"},"priority":"input_data"}

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.

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."},"publication_date":"2014-01-20","publication_name":{"en":"Journal of Chemical Engineering of Japan","ja":"Journal of Chemical Engineering of Japan"},"volume":"47","number":"1","starting_page":"14","ending_page":"20","languages":["eng"],"referee":true,"identifiers":{"doi":["10.1252/jcej.13we099"],"issn":["0021-9592"]},"published_paper_type":"scientific_journal"},"priority":"input_data"}

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.","ja":"表題反応の最適化を重金属で修飾していないパラジウム触媒を用い酸素加圧下の条件下で行った．さらに反応機構，活性座についての検討，担体効果についても検討した．γーアルミナに担持したパラジウム触媒において，プロピオン酸メチルの収率が74%に達成し，市販品触媒の活性を上回った．ベーマイトから調整したη-アルミナを担体とした場合，上記の収率を超えることはできなかったが，ベーマイとの焼成温度に触媒活性は依存した．溶媒効果や関連化合物の反応挙動により，この反応に対してはプロピオン酸を経て進む反応機構が提案された．XAFSの検討から担体のレドックスが触媒活性に影響を与えていることが明らかになった．"},"publication_date":"2013-07-20","publication_name":{"en":"Journal of Chemical Engineering of Japan","ja":"Journal of Chemical Engineering of Japan"},"volume":"46","number":"7","starting_page":"455","ending_page":"460","languages":["eng"],"referee":true,"identifiers":{"doi":["10.1252/jcej.12we259"],"issn":["0021-9592"]},"published_paper_type":"scientific_journal"},"priority":"input_data"}

Forced temperature cycling is an attractive mode of chemical reactor operation, since it can achieve higher conversion and selectivity for a variety of chemical reactions than steady-state operations.

This is because a large amount of energy is needed to quickly change the reactor temperature. With the reactor developed in this study, only 9 W of electric energy was required to achieve forced temperature cycling.
