Abstract:
A hydrogenation catalyst precursor, which comprises:a hydrocarbonaceous feedstock including at least about five volume percent of a boiling range fraction having a weight average boiling point at atmospheric pressure which is equal to or greater than 1000.degree. F.;a sulfide particle precursor fluid which includes a transition metal compound containing a sulfidable metal selected from the group consisting of molybdenum, cobalt, nickel, iron, vanadium, tungsten and mixtures thereof, wherein the sulfide particle precursor fluid is susceptible upon heating to precipitation which produces metal sulfide particles composed essentially of a metal sulfide of the sulfidable metal having an effective suspended particle size of about 0.001 to 50 microns; andan oxide particle precursor fluid which includes a compound containing an oxidisable element selected from the group consisting of magnesium, aluminum, silicon, phosphorous, calcium, scandium, titanium, gallium, germanium, zirconium, cerium, and mixtures thereof, wherein the oxide particle precursor fluid is susceptible upon heating to precipitation which produces oxide particles composed essentially of an oxide of the oxidisable element having an effective suspended particle size of about 0.001 to 50 microns.
