CO Hydrogenation over Alumina-Supported Sulfide Cluster Catalysts
Bimetallic Mo-Fe and Mo-Co sulfide clusters were anchored on AI,O, and used for CO hydrogenation. In addition to methane, significant amounts of dimethyl ether were produced. The reaction orders obtained from power rate laws for methanation indicated that the surfaces of the catalytic ensembles were not completely saturated by CO, in contrast to the observations for most conventional CO hydroge...
متن کاملContinuous flow hydrogenation using polysilane-supported palladium/alumina hybrid catalysts
Continuous flow systems for hydrogenation using polysilane-supported palladium/alumina (Pd/(PSi-Al(2)O(3))) hybrid catalysts were developed. Our original Pd/(PSi-Al(2)O(3)) catalysts were used successfully in these systems and the hydrogenation of unsaturated C-C bonds and a nitro group, deprotection of a carbobenzyloxy (Cbz) group, and a dehalogenation reaction proceeded smoothly. The catalyst...
متن کاملAcetylene and Ethylene Hydrogenation on Alumina Supported Pd-Ag Model Catalysts
Adsorption and co-adsorption of ethylene, acetylene and hydrogen on Pd-Ag particles, supported on thin alumina films, have been studied by temperature programmed desorption (TPD). The TPD results show that adding of Ag to Pd suppresses overall hydrogenat ion activity but increases selectivity towards ethylene, i.e. similar to that observed on real catalysts. The results are rationalized on the ...
متن کاملEffect of Nickel Particle Size on Alumina Supported Nickel Catalysts for p-Nitrophenol Hydrogenation
The catalytic hydrogenation of p-nitrophenol to p-aminophenol was investigated over alumina supported nickel catalysts prepared by impregnation reduction method and mechanical mixing method. The catalysts were characterized by XRD and FESEM. The results show that the nickel particle diameter of alumina supported nickel prepared by impregnation reduction method (denoted as Ni/Al2O3) is slightly ...
متن کاملCombinatorial Computational Chemistry Approach to the Design of Metal Sulfide Catalysts for Co Hydrogenation Process
Introduction Recently, computational chemistry made great impacts on the catalyst design and development. However, the computational chemistry is mainly employed to clarify the atomistic mechanism of the well-known catalytic reactions and to obtain the electronic information on the catalysts of which property and reactivity are well known experimentally. We suggested that such traditional compu...
