ABSTRACT:
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 cobaltmolybdate on alumina.
