초록

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°-600°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...

청구항

A process for forming a carbon-containing, poorly crystalline metal sulfide catalyst which comprises contacting one or more catalyst precursor salts, in the presence of sulfur and hydrogen and at elevated temperature, with a hydrocarbon for a time sufficient to form said catalyst wherein said precursor salt has the formula Bx[MOyS4-y]wherein x is 1 or 2 and y is any value between 0 and 4, wherein M is Mo or W and wherein B is (a) an ammonium ion, or (b) an alkyl or aryl ion wherein said ion may contain from 1-4 alkyl or aryl groups.
