Preparation and activity of solid-state hydrodesulfurization catalysts
(Elsevier, 1989-12)
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 ...
A microstructural investigation of model solid state hydrodesulfurization catalysts
(Elsevier, 1990-08)
Model molybdenum disulfide-based solid state synthesis catalysts have been prepared and tested catalytically in the HDS of thiophene. Both promoted and sulfur-deficient samples were prepared and the kinetic analyses were ...
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 ...
