<p>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.</p> |
