CO2 hydrogenation with renewable energy is one of the promising approaches to mitigate CO2 emissions and produce sustainable chemicals and fuels. The effect of adding H2O in the feed gas on the activi...
Heterogeneous catalytic hydrogenation is of significant importance for the production of pharmaceuticals, nutraceuticals, flavours and fragrances, agrochemicals and fine chemicals. Indeed, an average ...
The catalytic hydrogenation of nitrobenzene to aniline employing nickel impregnated on rutile, anatase, and high surface area titania supports has been investigated. The nickel is present in elemental...
Innovative catalysts based on a “porous glass” support material were developed and investigated for the reduction of benzalacetophenone. The easy preparation conditions and possibility to use differen...
Gas phase hydrogenation of crotonaldehyde was performed over 1 wt% Rh/ZnO-Al2O3 catalysts with various Zn/Rh atomic ratios. Monometallic Rh/Al2O3 was also prepared for comparison. The samples were pre...
A polymer-supported palladium-imidazole catalyst was used to catalyze the hydrogenation of various olefins under mild conditions. The rate of hydrogenation was studied. The effects of factors such as ...
应用浸渍法制备Pd/C催化剂,以大豆卵磷脂氢化反应前后碘值的变化作为指标,考察了制备条件对Pd/C活性的影响,并借助透射电镜的表征手段分析催化剂的形貌变化。结果表明,制备大豆卵磷脂氢化Pd/C催化剂的优化工艺为:原料炭经10%硝酸预处理后,在40℃的3.5mg/mL H2PdCl4溶液中浸渍2h,在30%甲醛、还原温度80℃、pH值1~2的条件下还原5h,并经80℃真空干燥获得成品。催化剂P...
Hydrogenation of naphthalene in the presence of CO was examined as a step in the organic hydride method for utilizing low grade hydrogen. Development of CO-tolerant hydrogenation catalysts will allow ...
An efficient and new method was developed to prepare the dopa analogue 11 in natural pepticinnamin via catalytic hydrogenation of dehydroamino acids (DDAA) with a good yield and ee. Product 11 is a ke...
Liquid phase citral hydrogenation over zeolite-supported monometallic Ni and bimetallic Ni-Sn catalysts was studied. The zeolite support materials were Na-Y, Na-mordenite, and clinoptilolite. Ni and S...
Waste cooking oil contaminated with fish oil has potential uses as a biodiesel fuel feedstock. The changes in properties of fish oil fatty acid methyl ester (FAME) caused by oxidation were first evalu...
The organic hydride method utilizes the reversible hydrogenation-dehydrogenation cycle of aromatic hydrocarbons for the storage and transportation of hydrogen. If low-grade hydrogen containing CO imp...
A series of bimetallic palladium-platinum (molar ratio Pd : Pt=4 : 1) catalysts supported on ytterbium (Yb)-modified ultrastable Y (USY) zeolite, Pd-Pt/Yb-USY, were prepared and characterized to inve...
The reaction pathway for hydrogenation of 2-butyne-1,4-diol involves parallel and consecutive isomerization as well as hydrogenation reactions forming other side products along with cis-2-butene-1,4-...
