Abstract
Abstract The process comprises contacting the high-boiling petroleum hydrocarbon feedstock under hydrocarbon conversion conditions and in the presence of hydrogen with a catalyst comprising a member selected from the group consisting of (1) uranium and a second hydrogenation metal, (2) their oxides, (3) their sulfides, and (4) mixtures thereof supported on a porous refractory inorganic oxide having an average pore diameter of about 100 Angstroms to about 300 Angstroms and a surface area in excess of 200 square meters per gram. The preferred second hydrogenation metal is molybdenum and the preferred porous refractory inorganic oxide is alumina.
