Method of catalyst manufacture

Abstract From the Canadian patent

A method of manufacturing a catalytic composite of a Group VIII metal, a Group VIB metal and a refractory inorganic oxide-boron phosphate carrier material. A refractory inorganic oxide hydrogel is precipitated from an aqueous solution admixed, with preformed, refractory inorganic oxide-boron phosphate fines impregnated with an aqueous solution of boric and phosphoric acids and the mixture recovered by filtration. The mixture is then dried, and further impregnated with a metal of Group VIII and a metal of Group VIB. The resulting composite is then dried and calcined.
