Slurry catalyst for hydroprocessing heavy and refractory oils
This patent describes a Group VIB metal sulfide slurry catalyst for the hydroprocessing of heavy hydrocarbonaceous oil or residue prepared by a process. It comprises sulfiding a Group VIB metal, ammonia-containing compound in an aqueous phase, in the substantial absence of hydrocarbon oil, with hydrogen sulfide, at a temperature less than about 350{degrees} F, to form a presulfided product without substantial loss of ammonia; separating ammonia from the presulfided product to form a sulfided product; charging the sulfided product into a hydroprocessing reactor zone at a temperature sufficient to convert the sulfided product into an active hydroprocessing catalyst; wherein the catalyst is characterized by a pore volume in the range of 10 to 300{Angstrom} radius pore size of from about 0.1 to about 1 cc/g and a surface area of from about 20 to about 400 m{sup 2}/g.
