High activity slurry catalysts for hydroprocessing heavy hydrocarbon oils are produced from Group VIB metal compounds by sulfiding an aqueous mixture of the metal compound with from greater than about 8 to about 14 SCF of hydrogen sulfide per pound of Group VIB metal.
A process for preparing a dispersed Group VIB metal sulfide catalyst for hydrocarbon oil hydroprocessing comprising: (a) treating a Group VIB metal oxide with aqueous ammonia to form a Group VIB metal compound aqueous mixture; (b) sulfiding said aqueous mixture of said Group VIB metal compound, with a gas containing hydrogen sulfide to a dosage greater than about 8 SCF of hydrogen sulfide per pound of Group VIB metal, to form a slurry; and (c) mixing said slurry with feed oil and a hydrogen-containing gas at a temperature from about 150°F. to 750°F. and ...
