    Unsaturated alcohols can be synthesized by selective hydrogenation of unsaturated carbonyl compounds, and they are used as important intermediates for perfumes and medicines. However, since selective hydrogenation of the carbonyl group in unsaturated carbonyl compounds is thermodynamically and kinetically unfavorable, development of effective heterogeneous catalysts for the reaction is desirable. In this study, hydrogenation of unsaturated carbonyl compounds (unsaturated aldehydes and unsaturated ketones) to the corresponding unsaturated alcohols was investigated using metal oxide modified noble metal catalysts, showing that Ir-FeOx/MgO catalyst is effective for the reaction.

    Selective hydrogenation of the carbonyl group of unsaturated ketones over heterogeneous catalysts is an useful reaction for the synthesis of unsaturated alcohols. Selective hydrogenation of unsaturated ketones to unsaturated alcohols was investigated using benzylideneacetone as a model substrate. MgO supported Ir-FeOx catalyst(Ir-FeOx/MgO catalyst Fe/Ir molar ratio=0.5) showed high activity and selectivity for the reaction. The Ir-FeOx/MgO catalyst was characterized by various techniques such as XPS and FT-IR.

Acetonitrile has high solubility of carbon dioxide and is the most effective solvent. In optimized reaction conditions, 2-oxazolidinone is obtained from 2-aminoethanol with 97% yield. When this catalyst system was applied to aminoalcohols which have &ndash;OH and &ndash;NHR groups at 1 and 2-positions or 1 and 3-positions, five- and six-membered-ring carbamates can be selectively synthesized in high yield.

    The Ni/Mg/Al catalysts were prepared from the calcination and reduction of hydrotalcite-like compounds. The Ni/Mg/Al catalysts have a nanocomposite structure of Ni metal particles and Mg(Ni, Al)O particles. The Ni/Mg/Al catalysts showed high catalytic performance in the steam reforming of biomass-derived tar. In the present study, we also prepared Ni-Cu/Mg/Al catalysts from the calcination and reduction of hydrotalcite-like compounds. The performance of the Ni-Cu/Mg/Al catalysts was investigated in terms of catalytic activity, suppression of coke deposition in the steam reforming of biomass-derived tar.

    More details Close

    The infrared (IR) chemiluminescence spectra of CO2 molecules were measured during the steady-state CO oxidation over Pt(110) and Pt(111) surfaces. Analysis of the IR emission spectra indicates that the bending vibrational temperature (TVB), as well as the antisymmetric vibrational temperature (TVAS), was higher on Pt(110) than on Pt(111). On the Pt(110) surface, the highly excited bending vibrational mode compared to the antisymmetric vibrational mode was observed under reaction conditions at low CO coverage (θCO<0.2) or at high surface temperatures (TS≥700 K). This can be related to the activated complex of CO2 formation in a more bent form on the declined (111) terraces of the Pt(110)(1×2) structure. On the other hand, at high CO coverage (θCO≥0.2) or at low surface temperatures (TS<650 K), TVAS was higher than TVB, which can be caused by the reconstruction of the Pt(110)(1×2) surface to the (1×1) form with high CO coverage.

    We investigated the effect of reductants over Fe-MFI catalysts (Fe-MFI) based on the catalytic performance in N2O reduction in the absence of oxygen. The TOFs of N2O decomposition and N2O reduction by various reductants (H2,CO, CH4)increased with increasing Fe/Al ratio (Fe/Al≥0.15). As the result of extended X-ray absorption fine structure (EXAFS) analysis, only mononuclear Fe species were observed over Fe(0.10)-MFI after N2O or O2 treatment. On the other hand, binuclear Fe species were also observed over Fe(0.40)-MFI after treatment with N2O. More reducible Fe species, which gave lower-temperature O2 desorption, can be due to Fe binuclear species. Since the N2O reduction with reductants proceeds via a redox mechanism, the reducible binuclear Fe species can exhibit higher activity than the mononuclear one. Furthermore, CH4 can be oxidized under the presence of N2O more easily than can H2 and CO, although it is generally known that the reactivity of methane is very low.

    The selective catalytic reduction (SCR) of N2O with CH4 in the presence of excess O2 was studied over ion-exchanged Fe-BEA catalyst by the observation of reaction intermediates in order to elucidate the reaction mechanism. From the results of activity tests, SCR of N2O with CH4 in the presence of excess O2 proceeded at much lower reaction temperature than N2O decomposition over the Fe-BEA catalyst. The profiles of temperature programmed desorption of O2 after N2O pretreatment gave a new desorption peak at lower desorption temperatures compared to the case of O2 pretreatment. However, the oxygen species desorbed at the lower temperatures did not react with CH4 in the profiles of temperature programmed reaction. From the structural analysis by means of extended X-ray absorption fine structure, a Fe-Fe bond was observed on the Fe-BEA catalyst after N2O treatment. This suggests that binuclear species can be formed over the Fe-BEA catalyst. In the in-situ FTIR observation, the methoxy and formate species were observed during the SCR reaction. We measured the reaction rates of these surface species with N2O and O2, and this is related to the selective reduction of N2O with CH4.

    The infrared chemiluminescence technique was applied to the steady-state CO oxidation by NO on Pd(111) and Pd(110) to measure the internal energy of CO2 desorbed from surfaces. In this paper, on the basis of the results of CO oxidation by O2, we elucidate the CO2 formation mechanism of CO + NO reaction. From the comparison of IR emission spectra of CO2 between CO + NO and CO + O2 reactions, it is found that the vibrational energy states of CO2 in CO + NO reaction are similar to those in CO + O2 reaction. This indicates that the reaction path of CO2 formation in CO + NO is the same as that in CO + O2. The vibrational states are much dependent on the surface structure: the CO2 molecules produced on flat Pd(111) were highly excited (especially bending mode) than those on Pd(110) which has atomically rough surface.

    More details Close

    Development of Ni-containing catalysts for steam reforming of tar derived from the cedar pyrolysis is introduced. The optimized Ni-Fe/α-Al_2O_3 catalyst showed higher activity and resistance to coke formation than Ni/α-Al_2O_3 by the Ni-Fe alloy formation. In addition, the Ni/Mg/Al catalysts prepared via hydrotalcite precursors showed higher activity and resistance to coke formation than Ni/Al_2O_3 and Ni/MgO by the nano-composite formation with Ni metal and Mg(Al, Ni)O particles.

    The conventional methods of biomass gasification to hydrogen and synthesis gas have been carried out at high temperature. The purpose of this study is catalyst development for energy efficient power generation by catalytic gasification of biomass at lower reaction temperature. We have tested Rh/CeO_2/SiO_2 catalysts with various CeO_2 content in cellulose gasification. We have found that the optimum content was 35 wt% CeO_2 From the comparison between our catalyst and conventional methods (steam reforming Ni catalyst, dolomite, non-catalyst) in terms of C-conversion to gas and cold gas efficiency, Rh/CeO_2/SiO_2 (35) catalyst exhibited much higher performance than other methods. It is suggested that our catalyst can enhance the energy efficiency of power generation utilizing biomass gasification.

    The conventional methods of biomass gasification to hydrogen and synthesis gas have been carried out at high temperature. The purpose of this study is the development of the novel catalytic process for biomass gasification at low temperature (773-873 K) with high energy efficiency. We used the cellulose as the model compound of biomass, and batch- and continuous- feeding fluidized bed reactor. From the results of the reaction tests using various oxide supports and metal supported catalysts, it is found that Rh/CeO_2 exhibited higher performance than other catalysts. However, Rh/CeO_2 catalyst deactivated with time on stream because of the sintering of CeO_2 support. Furthermore, we have prepared Rh/CeO_2/SiO_2,which gave higher C-conversion to gas and was more stable than Rh/CeO_2. From the comparison of the performance with conventional methods, it is found that the novel catalytic gasification at much lower temperature is a highly energy-efficient process.

    Re oxide catalyst dispersed on CeO2 modified with Pd metal was an effective heterogeneous catalyst for the conversion of methylglycosides with cis-vicinal OH groups by the deoxydehydration with H2 over Re oxide species as a catalytically active site and the subsequent hydrogenation of C-C double bond to give corresponding dideoxysugars in high yield. Furthermore, some produced dideoxysugars can be converted to optically active triols by hydration and hydrogenation in high yield and high enantio excess.

    Protein(peptide) can be regarded as one of biomass-derived key materials, and can be obtained from green biomass. Therefore, development of transformation methods of protein is required. Dissociation of the amide bonds is one strategy for that, however, the methods that use stoichiometric amount of acids or bases are used as main ones, and alternative environmentally-benign methods are required. In this study, we investigated heterogeneous catalysts that enables direct cleavage of C-N bond in amide by hydrogenation, and found that N2-treated Ru/CeO2 catalyst showed high activity and selectivity for the reaction and that the small Ru particles over Ru/CeO2 are responsible active species for the high performance.

    Organic chemicals including resins and polymers have been produced mainly from petrolium. In order to conduct a sustainable society, one of important subjects is the development of environment-bengin method for the production of chemicals. One of the remarkably efficient methods is the production of various chemicals from biomass is to recude the oxygen content in the biomass-derived substrate. Usually, high pressure hydrogen is used for the reduction. In this research, the purpose is to develop the catalysts for C-O hydrogenolysis using the intramolecular hydrogen transfer, and it is found that MoOx-modified Rh metal catalysts was very effective to this reaction system.

    We developed the ceria-supported rhenium catalyst modified with palladium (ReOx-Pd/CeO2 (Re = 2 wt %, Pd/Re = 0.25)) for the hydrodeoxygenation of 1,4-anhydroerythritol to tetrahydrofuran with hydrogen as a result of the catalyst optimization. This catalyst was applicable to the reaction of sugar alcohols, and mono-alcoholsand diols are obtained in high yields from substrates with even and odd numbers of OH groups, respectively. It is verified that the high catalytic performance of the catalyst is due to the tetra/hexavalent redox cycle redox cycle of the isolated Re species on CeO2 surface and the promotion of the reduction of Re species by Pd.

NO Dissociation does not take place on Pd (111), and nascent oxygen from NO is formed on Pd (110) because NO dissociation is limited. (1-3) CO+0_2 reaction on Pt (110), Pt (111) Activity was higher on Pt (110) than on Pt (111).

(2-2) Comparative study between methane and ethane in the catalytic paratial reaction on Pt and Rh Based on the results of the reaction order measurements one possible explanation for the promotion is that energetically activated methane and ethane react with adsorbed oxygen and produce methoxy and ethoxy species, which are regarded as precursors for hydrogen formation.

    A recommended preparation procedure and applying method for some catalytic reactions were proposed based on the results of this investigation. As the starting material for catalyst preparation, JRC-ZRO-2 and-5 supplied by Catalysis Society of Japan are recommended. Zirconia gel should be well dried before sulfation at 300 ℃ or below. Two preparation methods of equilibrium adsorption method and ammonium sulfate kneading method had been investigated. The zirconia gel was sulfated with high reproducibility in both procedure. The sulfated zirconia with high surface area and high sulfate content was obtained when the non crystallized gel was used. The reproducibility of sulfate content on the surface was high in the ammonium sulfate kneading method. However, there was a tendency that unnecessary sulfate ions, which did not relate to the formation of active sites, remained on the surface. The recommended calcinations temperature is 650 ℃. From the reason of temperature distribution in a furnace, the calcinations at 600 ℃ is strongly recommended. The sulfated zirconia can be kept without care because this was calcined at high temperature. This can be applied for several reactions without pretreatment. It is desirable to remove adsorbed water by heating before use. The pretreatment at 500 ℃ is avoided because the decrease of acid amount was observed in some cases. Thermogravimetry is recommended as the method to confirm the sulfated zirconia production. The temperature of weight decrease accompanying the decomposition of sulfated ions should be checked.

    再生可能資源バイオマスの熱分解に由来するタールを水素や合成ガスへと変換する触媒の開発及びその作用機構の解明を行ってきた。我々はこれまでバイオマスのガス化反応において、反応温度の低下およびTarを効率的に合成ガスへと改質することで、反応効率の向上を目的とした触媒を使用したプロセスの研究を行ってきた。本研究では、特に高価な金属であるRhに代わり安価なNiを用いたバイオマスの水蒸気ガス化用の触媒の開発を行った。まずさまざま酸化物を担体を使用したNi担持触媒について活性試験およびH_2-TPR,XRD,BET,H_2吸着量測定、TGA等のキャラクタリゼーションを通じて、触媒の性能評価を行った。その結果、Ni/Al_2O_3触媒がTarの改質について高い性能を示し、Ni/CeO_2触媒がガス化反応中に触媒上に生成し、触媒の活性劣化の原因となるCokeの抑制に高い効果を示した。Tar改質はNi/Al_2O_3の高いNi分散性に因るもので、Coke抑制はCeO_2担体の特性に因るものである事が分かった。 先の結果を踏まえ、Al_2O_3とCeO_2を組み合わせたNi触媒の高活性を期待し、調製法やNi,CeO_2の担持量を変えた様々なNi/CeO_2/Al_2O_3触媒を調製し、触媒の最適化および各種のキャラクタリゼーションを行い触媒を評価した。活性試験からNi/Al_2O_3触媒へのCeO_2添加によるCokeの抑制効果が確認された。最適化の結果、共含浸法(Ni前駆体とCeO_2前駆体をAl_2O_3担体上に同時に担持する方法)で調製した、Ni/CeO_2/Al_2O_3が最も高い活性を示した。そしてこの触媒を含め、逐次含浸法(Al_2O_3担体にCeO_2を担持した後、Niを担持する方法)により調製したNi/CeO_2/Al_2O_3とNi/Al_2O_3について担体効果の際と同様のキャラクタリゼーションに加え、Ni K-edge EXAFS,TEM観察を行った。その結果は共含浸で調製した触媒はNi/Al_2O_3および逐次含浸で調製した触媒に比べ、Ni粒子がこう分散した微粒子として存在し、またNiとCeO_2との強い相互作用の存在が明らかになり、これが、高い性能につながっていることを明らかにした。

    二酸化炭素の化学的な変換は、その安定性から容易ではないが、最近研究代表者らは、酸塩基量機能性固体触媒を用いることにより、アルコールと二酸化炭素のみから、有用な有機カーボネートを選択的に合成できることを見出してきた。触媒としては、セリア、ジルコニア、セリア-ジルコニア固溶体触媒が有効であることを明らかにしてきた。ここでは特に、希土類金属についてさまざまな酸化物で反応試験を行ったところ、セリアが際立った性能を見出すことを明らかにした。また、アルコールとしては、メタノール、エタノール、1-プロパノール、2-プロパノール、エチレングリコール、プロピレングリコールなどを対象とした。いずれの反応物において、セリア触媒を用いた場合、ほぼ選択的に対応するカーボネートを合成できることを示した。また、エチレングリコールやプロピレングリコールを用いた場合、カーボネートとしては分子内のものと分子間のものが想定される。これらは赤外線吸収分光法を用いることにより、その寄与を知ることができるが、本触媒反応系では、ほぼ完全に分子内で反応が進行し、分子間のものはほとんど合成されなかった。また、反応機構の解明として、拡散反射赤外吸収分光法を用いて、表面吸着種の観測を行ったところ、いずれのアルコールを用いた場合でも、吸着によりアルコキシドが生成し、二酸化炭素の導入により容易にアルキルカーボネートが生成することが確認できた。このアルコキシドへの二酸化炭素分子の挿入が容易であることが、反応選択性の向上につながっていると示唆された。

    In methane reforming, one of the most serious problems is carbon deposition during the reaction. However the investigation of the route of carbon formation and the structure of formed carbon is not enough. Especially, in the development for the long-life catalyst, the information is very important. The research of the purpose is the elucidation of the relation between the catalyst life and carbon deposition behavior. I investigated the methane reforming with CO_2, steam and CO_2+steam over various catalysts. The activity test, reaction temperature dependence, space velocity dependence, and total pressure dependence have been investigated. As a result, NiO-MgO solid solution catalysts showed excellent performance. Especially, the solid solution catalyst with low surface area exhibited much higher resistance to carbon deposition that that with high surface area. From the analysis ol the carbon deposition at various position of the catalyst bed, it is found that the carbon deposition at the inlet of the catalyst bed was inhibited. This indicates that the carbon formation from the methane decomposition is inhibited. Furthermore, the effect of other metal addition is also investigated. At present, the addition of Sn inhibited the carbon deposition. The excellent catalyst is also applied to the fluidized reactor system for the methane reforming with internal heat supply using oxygen introduction with the reforming agents. Fluidization reaction system enhanced the methane conversion and it is found that the carbon deposition is not observed at all under highly pressurized condition. This is caused by the in-situ reproduction ol the active catalyst in the reactor.

    ジルコニア触媒の表面修飾による酸性・塩基性の強さ及び量の制御を行い、触媒反応により最適な反応活性点の構築を試みた。それらの中で特にリン酸で修飾した触媒が高い活性を維持した。そのとき、想定される副反応であるメタノールの脱水反応が進行する可能性があるが、上記の触媒ではそれは全く進行せず、炭酸ジメチルが選択的に生成した。FTIR、ラマン分光法、核磁気共鳴法、昇温脱離法などを用いた触媒表面のキャラクタリゼーションの結果から、リン酸修飾ジルコニア触媒では、単なるジルコニア触媒は持たない弱いブレンステッド酸点が生成しており、これが活性をあげる原因となっていることが分かった。さらに、金属酸化物の探索を行い、あらたにセリアが高い炭酸ジメチル合成活性を持つことを見出した。セリアはジルコニア系触媒と異なった挙動をとった。ジルコニア系触媒は、高温で焼成すると表面積が低下し、活性が低下していくのに対して、セリア触媒は、高温焼成することによって表面積が低下するほど、活性が向上してくると言う挙動をとった。現在、その理由については検討中であるが、高温焼成により結晶化度が向上したことによる表面状態の変化が関連しているものと考えている。さらに、セリアージルコニア系固溶体触媒も調製し、触媒作用を検討したところ、固溶体生成にともない、活性がさらに向上した。特に、低温活性も高く、100℃以下でも炭酸ジメチルの生成が観測された。これについても今後、表面構造解析やキャラクタリゼーションを行い、活性構造を解明していく必要がある。

    Solid acid site is the catalytic active site for the isomerization, hydrocracking, disproportionation of hydrocarbons. The problem in these kinds of reaction is the carbon deposition on the solid acid catalyst which are formed by the polymerization, and this deactivates the catalyst. In the case that noble metals are introduced to the solid acid catalyst by supporting or physically mixing, the deactivation is considerably inhibited. It has been reported that the cofeed of hydrogen is very effective to the inhibition of the deactivation. The effect of hydrogen has been expalined by the hydrogen spillover phenomenon. Hydrogen molecule dissociates on metal surface and spills over to the acid site. The spilled over hydrogen regenerates the acid site and supplies the hydride to the hydrocarbon reaction intermediate. We have proposed the reaction mechanism on the basis of the spillover effect. In this study, we observed the behavior of adsorbed pyridine on the acid site under hydrogen flowing by means of FTIR.From the comparison between zeolite supported Pt catalyst and the physical mixture of zeolite with Pt/SiO_2 catalyst, it was found that spillover hydrogen promotes the desorption of adsorbed pyridine on Lewis acid site. This result suggests the formation of hydride as the spillover hydrogen.

    本研究の目的は、メタノールと炭酸ガスから炭酸ジメチルの新規直接合成用の触媒を開発することである。従来は、メタノールと一酸化炭素と酸素を原料とするプロセスがメインである。そのため、これまでの触媒反応プロセスとは大きく異なったコンセプトと触媒設計が必要となる。本反応は、これまでほとんど成功例がなく、進行しやすい反応ではない。本研究では、この難しい反応に対して、ジルコニア触媒が非常に選択的に炭酸ジメチルを合成する触媒となりうることを明らかにした。化学平衡的な制約もあるため、収率は低いものの、副生成物として予想されるジメチルエーテルの生成は観測されなかった。本触媒については、アンモニアや二酸化炭素のTPDから、二酸化炭素の吸着に伴う強い酸点の生成が示唆されており、この種が活性とよく対応していることを明らかにした。そこで、触媒表面の酸性をより強いものにするために、リン酸を添加した触媒を調製したところ、大きな活性の向上が観測された。この手法による活性促進により、反応温度を40度程度落とせることが明らかになり、さらに反応の低温化が実現すれば、無機系脱水剤の使用可能領域に突入し、水のその場除去が可能となれば、転化率の劇的な増加が予想されている。

    Polypropylene, polystirene and polyethylene could be decomposed effectively to liquid hydrocarbons on an active carbon supported sulfide iron catalyst. Also codecomposition of these plastics was also available by using the same batch type reactor while high-pressure hydrogen coexisted. This decomposition is believed to be a radical reaction process. Addition of a small amount of hydrogen sulfide or cumene, as chain initiator, to the reaction system remarkably increased the liquid hydrocarbon selectivity and suppressed the formation of gaseous and residue-like hydroccarbons.

    Recently it is pointed out to be necessary to development of new process for direct conversion of natural gas to chemical material. From the results of researches, C_2 hydrocarbo was found to be formed via methyl radicals in oxidative coupling of methane. In this case, th side reaction of methyl radical with oxygen in gas phase proceeded, therefore it is suggested t be the limitation of yield of C_2 hydrocarbons. In this study we investigated the formation of C_2 hydrocarbons from methane (a main component of natural gas) and carbon material (coal). We used coal char as the carbon material since amorphous carbon is favorable in terms of its reactivity. In our study we especially used Yallourn brown coal. On the reaction between Yallourn char and methane, the gas product was observed at higher temperature than 1273K But under the reaction condition on which methane was only feeded, large amount of coke w deposited on carbon surface. In order to avoid this coke deposition, we added hydrogen to methane flow. This is the utilization of hydrogen spillover phenomena from the combination of hydrogen gas and supporte metal, metal oxide and metal sulfided catalysts. It is possible to control of the concentration of hydrogen species on the carbon surface. From these experiment, it is observed that decrease of coke amount formed during reaction, and at the same time the decrease of methane conversion probably because the adsorption of hydrogen on the radical center of carbon surface which seems to be active site of dehydrogenative activation of methane.

    バイオマスに由来する化学品製造のための固体触媒の開発を行い、触媒反応プロセスの構築を目的とする。いずれの基質の反応においても、研究としての実験操作は、①触媒調製、②触媒反応試験(回分式及び流通式)、③触媒構造解析、④活性構造上での反応機構の解明、となる。対象とする触媒反応は以下のとおりとなる。 a) フラン類の水素化反応:予備的な検討から、Pd-Ni合金触媒が有効であるという知見を得ており、現時点で、フルフラール及びHMFの完全水素化収率が99%及び97%を達成している(Catal. Commun., 2010)。これらについては、触媒構造解析及び反応機構解明が必要であり、さらにそれらを踏まえた触媒改良も検討する。また、フルフラールについては、沸点も低いことから、流通系での反応も検討する。 b)環状エーテルとポリオールの水素化分解反応:テトラヒドロフルフリルアルコールの水素化分解による1,5-ペンタンジオールの製造に有効な触媒Rh-ReOx/SiO2及びRh-ReOx/Cをベースとして、上記のHMFの水素化により生成する2,5-ビス(ヒドロキシメチル)テトラヒドロフランの水素化分解を行う。特に、1,2,6-ヘキサントリオールの内側のOHを水素化分解することで1,6-ヘキサンジオールを与えるプロセスについても検討する。環状エーテルについては、ソルビトールから高収率で誘導されるイソソルビドを水素化分解し、さらに内側の2つのOHを水素化分解して1,6-ヘキサンジオール合成を試みる。グリセリンの水素化分解反応による1,3-プロパンジオール製造については、予備的な検討から、Ir-ReOx/SiO2触媒が特殊な有機溶媒を用いず、水溶液系や無溶媒で世界最高収率を示すことを明らかにしており、触媒構造解析と反応機構解明を行い、さらなる高性能化を目指す。以上の水素化分解反応で得られた知見を生かし、直接キシリトールやソルビトールから1,5-ペンタンジオール、1,6-ヘキサンジオールを与える触媒の可能性を探る。 c) C-C結合クラッキング反応:セルロースやソルビトールを原料として、C-O結合を維持して、C-C結合をできれば、エチレングリコールをできることになる。予備的な検討においては、グリセリンを反応基質として、比較的選択的にエチレングリコールを与える触媒としてNi-Pt系バイメタル触媒が有効であることを見出している(Chem. Lett., 2010)。これらの触媒を展開し、他のより高分子量の基質に用いる触媒の設計に活用する。
