A process for converting a carbonaceous chargestock is described comprising a hydrocarbon to produce lower boiling products which process comprises reacting the carbonaceous chargestock with hydrogen at a hydrogen partial pressure from about 50 to about 5000 psig at a temperature from about 800/sup 0/ to about 900/sup 0/F in the presence of catalyst concentrate having been prepared by the steps which comprise: (a) forming a mixture of hydrocarbonaceous oil comprising constituents boiling above about 1050F/sup 0/ and the aqueous solution of phosphomolybdic acid in an amount to provide from about 0.2 to 2 weight percent molybdenum, calculated as elemental molybdenum, based on the hydrocarbonaceous oil to produce a water-containing catalyst precursor concentrate; (b) drying the water-containing catalyst precursor concentrate to remove the water and produce a substantially water-free catalyst precursor concentrate; (c) contacting the water-free catalyst precursor concentrate with added hydrogen sulfide at a temperature from about 50/sup 0/ to 600/sup 0/F and a hydrogen sulfide partial pressure ranging from about 14.7 psia to about 100 psia to produce a sulfided catalyst precursor concentrate; (d) separating the unreacted hydrogen sulfide from the sulfided catalyst precursor concentrate; and (e) heating the sulfided catalyst precursor concentrate.
