    摘要: Catalysts comprising a carbon-containing sulfide of molybdenum or tungsten are prepared by contacting, in the presence of sulfur, hydrogen and a hydrocarbon, ammonia and ammonium substituted molybdate, thiomolybdate, tungstate and thiotungstate salts at a temperature of from about 200.degree.-600.degree. C. These catalysts are useful for hydrotreating reactions. In a preferred embodiment, these catalysts will be promoted with certain transition metal sulfides, such as cobalt sulfide, which results in catalysts having greater activity than conventional catalysts such as cobalt-molybdate on alumina.

    摘要: Catalyst supports, catalysts, method for the preparation thereof, and dimerization processes therewith are provided. Catalyst supports consist essentially of potassium carbonate with a crush strength of at least 5 pounds and at least one carbonaceous compound. Catalysts consist essentially of at least one elemental alkali metal deposited on the novel catalyst supports. Optionally, the catalysts further consist essentially of at least one promoter selected from the group consisting of elemental copper, elemental cobalt, and finely divided stainless steel.
