A slurry hydroconversion process is provided in which a catalyst precursor concentrate comprising an aqueous solution of phosphomolybdic acid and a heavy oil is contacted with hot hydrogen to vaporize the water from the concentrate. The resulting catalyst precursor concentrate is introduced into a hydrocarbonaceous chargestock and the resulting mixture is heated in the presence of added hydrogen to convert the phosphomolybdic acid to a solid molybdenum-containing catalyst. The resulting slurry is subjected to hydroconversion conditions.

A slurry hydroconversion process for converting the heavy constituents of a hydrocarbonaceous oil to lower boiling products which comprises the steps of: (a) forming a mixture of a heavy hydrocarbonaceous oil and an aqueous solution of phosphomolybdic acid in an amount to provide in said mixture from about 0.2 to 2 weight percent molybdenum, calculated as elemental metal, based on said hydrocarbonaceous oil to produce a catalyst precursor concentrate; (b) contacting said catalyst precursor concentrate with a hot hydrogen-containing gas to vaporize water from said catalyst precursor concentrate; (c) introducing at least a portion of the catalyst precursor concentrate resulting from step (b) into a hydrocarbonaceous chargestock; (d) heating the mixture resulting from step (c) in the presence of an added hydrogen-containing gas at conditions to convert said phosphomolybdic acid to a solid molybdenum-containing catalyst; and (e) hydroconverting the resulting slurry comprising said hydrocarbonaceous chargestock and said solid molybdenum-containing catalyst at a temperature from about 800°to 900°F. and a hydrogen partial pressure ranging from about 100 psig to about 5000 psig, wherein at least a portion of the heavy constituents of the oil are converted to lower boiling products.
