A hydrocarbon treating process which comprises contacting a hydrocarbonaceous oil feed at treating conditions with a catalyst comprising a composition comprising a metal component, carbon and hydrogen deposited on a support selected from the group consisting of solid metals and metal alloys of metal

A hydrocarbon treating process which comprises contacting a hydrocarbonaceous oil feed at treating conditions with a catalyst comprising a composition comprising a metal component, carbon and hydrogen deposited on a support selected from the group consisting of solid metals and metal alloys of metals of Group IB, II, III, IV, VB, VIB, VIIB, VIII and mixtures thereof of the Periodic Table of Elements, said support having a surface area of less than about 5 square meters per gram, and the metal constituent of said metal component of said composition being selected from the group consisting of metals of Groups II, III, IV, V, VIB, VIIB, VIII and mixtures thereof of the Periodic Table of Elements, said composition having a surface area of at least about 50 m2/g, said catalyst having been prepared by the steps which comprise: (a) dispersing in a hydrocarbon oil having a Conradson carbon content up to about 50 weight percent, (1) a thermally decomposable metal compound in an amount sufficient to provide a ratio of atoms of oil Conradson carbon to atom of metal constituent of said thermally decomposable compound of less than about 750 to 1, said metal constituent being selected from the group consisting of Group II, Group III, Group IV, Group V, Group VIB, Group VIIB, Group VIII of the Periodic Table of Elements and mixtures thereof, and (2) said support; (b) heating the resulting mixture in the presence of a gas selected from the group consisting of a hydrogen-containing gas, a hydrogen sulfide-containing gas and a gas comprising hydrogen and hydrogen sulfide, and (c) recovering said supported catalyst.
