ABSTRACT:
A catalytic composite comprising a refractory inorganic oxide-supported Group VIB and Group VIII metal component is disclosed. The catalytic composite is characterized by a method of preparation which comprises coextruding a precursor compound of the Group VIB metal component, a precursor compound of the Group VIII metal component, and a finely divided refractory inorganic oxide admixed with hydrogen peroxide and sufficient water to provide an extrudable dough. The coextruded product is subsequently dried and calcined to yield an improved catalytic composite, particularly with respect to the hydrodesulfurization of residual fuel oils.
