In the hydroconversion of carbonaceous materials such as hydrocarbonaceous oils and coal or mixtures thereof, in which inorganic poly acids comprising molybdenum or tungsten or salts thereof are used as catalyst precursors which are converted to catalysts, the use of a combination of phosphoric acid and said poly acids or salts thereof as catalyst precursor wherein the amount of phosphoric acid is such as to provide from about 0.5 to about 3.5 atoms of phosphorus per atom of molybdenum or tungsten results in a catalyst having improved activity.

In a process for the hydroconversion of a carbonaceous material which comprises: (a) forming a mixture of said carbonaceous material and a poly acid selected from the group consisting of isopoly acids and heteropoly acids and salts thereof, wherein said poly acid comprises at least one metal constituent selected from the group consisting of molybdenum and tungsten; (b) converting said poly acid to a catalyst within said mixture in the presence of a hydrogen-containing gas by heating said mixture to an elevated temperature; (c) reacting the resulting mixture containing said catalyst with hydrogen under hydroconversion conditions; and (d) recovering a normally liquid hydrocarbon product, the improvement which comprises: adding said poly acid and phosphoric acid, to said mixture said phosphoric acid being added in an amount such as to provide a ratio from about 0.5 to about 3.5 atoms of phosphorus per one atom of said metal constituent, said catalyst of step (b) being the conversion product of said phosphoric acid and said poly acid.
