Solid state synthesis and characterization of model hydrodesulfurization catalysts
(Elsevier, 1989-10)
Solid-state reactions of elemental sulfur with metallic cobalt and molybdenum powders were used to synthesize model catalysts for hydrodesulfurization (HDS). The resulting materials had a general stoichiometry of Co2xMo1-xS2 ...
Selective oxidation of methane over vycor glass, quartz glass and various silica, magnesia and alumina surfaces
(Elsevier, 1988)
The reaction between methane and oxygen was investigated in empty Vycor glass and quartz tubes and over various silica compounds in powder form. In the temperature range of 893-993 K and with methane-to-oxygen ratios close ...
Magnesium oxide as a catalyst support: The influence of chlorine
(Elsevier, 1982-07-01)
The properties of MgO when used as a support material for Ru-Au catalysts have been investigated by thermal analysis, chemical analysis, surface area measurements and X-ray diffraction. During impregnation the support ...
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 ...
CO hydrogenation over alumina-supported sulfide cluster catalysts
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1989-01)
Bimetallic Mo-Fe and Mo-Co sulfide clusters were anchored on Al 2 O 3 and used for CO hydrogenation. In addition to methane, significant amounts of dimethyl ether were produced. The reaction orders obtained from power ...
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 ...
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 ...
