Abstract
An improved method of preparing a catalyst comprising a Group VIII metal and a Group VIB metal component impregnated on a refractory inorganic oxide support or carrier material, said catalyst being especially useful in the hydrorefining of petroleum hydrocarbon fractions and particularly effective for the conversion of sulfurous components contained therein. A more active catalyst results from the use of an impregnating solution comprising an anionic complex of a Group VIB and a Group VIII metal.

In the manufacture of a hydrorefining catalyst comprising a Group VIB and a Group VIII metal component impregnated on a refractory inorganic oxide carrier material wherein said carrier material is impregnated with an aqueous solution of a Group VIB metal compound and a Group VIII metal compound and thereafter dried and calcined, the improvement which comprises impregnating said carrier material with an aqueous solution comprising an anionic complex of a Group VIB and a Group VIII metal sufficient to provide a final catalyst product containing from about 5 to about 20 wt. % Group VIB metal, and with a simple salt of a Group VIII metal sufficient in combination with said anionic complex to provide a final catalyst product containing from about 0.1 to about 10 wt. % Group VIII metal.
