Cyclopropane hydrogenation on Ru and Ru---Au catalysts
(Elsevier, 1980-01)
The rate of reaction between cyclopropane and hydrogen was measured in a flow system on unsupported Ru, Ru/SiO2, andRu/MgO. The effect of the addition of Au to Ru/MgO was also investigated. The temperature was in the range ...
FTIR study of bimetallic Pt-Sn/Al2O3 catalysts
(Elsevier, 1992-12)
A series of Pt-Sn/Al2O3 catalysts supported on Degussa nonporous alumina were characterized by infrared spectroscopy of adsorbed CO. The nominal platinum loading was kept constant in the catalysts at 1 wt% and the nominal ...
The influence of hydrazine reduction on metal dispersion and support morphology in bimetallic Ru---Au/MgO catalysts
(Elsevier, 1986-03)
The influence of hydrazine reduction on metal dispersion, particle size distribution, and support morphology was investigated for a series of bimetallic Ru-Au/MgO catalysts. The catalysts were prepared by impregnation of ...
Chemisorption studies of promoted solid-state HDS catalysts
(Elsevier, 1992-06)
Oxygen pulse chemisorption measurements were made on a series of model HDS catalysts synthesized from solid-state reactions of elemental starting materials. Three different promoter atoms having the following catalyst ...
Microstructure and reactivity of supported bimetallic platinum-gold catalysts
(Elsevier, 1989-12)
In this paper an attempt is made to correlate the microstructure of a supported bimetallic catalyst system with its activity and selectivity. A series of bimetallic platinum-gold catalysts supported on high-surface-area ...
The role of the zeolite in the hydrogenolysis of C2 and C3 hydrocarbons on RuNaY catalysts
(Elsevier, 1986-02)
The catalytic properties for the hydrogenolysis of ethane, propane and cyclopropane of a series of highly dispersed RuNaY catalysts have been investigated. These catalysts have activities and selectivities for ethane and ...
Model hydrodesulfurization catalysts: Solid state synthesis and characterization of iron containing molybdenum sulphide
(Elsevier, 1989)
Model catalysts for hydrodesulfurization were synthesized via solid state reactions of elemental sulfur with metallic iron and molybdenum powders. The starting materials had a general stoichiometry of Fe2[alpha]Mo1-[alpha]S2 ...
CO hydrogenation catalyzed by alumina-supported osmium: Particle size effects
(Elsevier, 1985-10)
Alumina-supported catalysts were prepared by conventional aqueous impregnation with [H2OsCl6] and by reaction of organoosmium clusters {[Os3(CO)12], [H4Os4(CO)12], and [Os6(CO)18]} with the support. The catalysts were ...
