A hydrocarbon conversion catalyst containing cobalt and a Group VIB metal and having a substantially uniform cross-sectional phosphorus distribution is prepared by impregnating support particles with a solution containing dissolved cobalt, phosphorus, and at least 17 weight percent of Group VIB metal components, calculated as the trioxides, having a pH of less than 1.2, and characterized by an extinction coefficient in the ultraviolet spectrum of about 0.7x104 to about 1.8x104 liters/cmxmoles of Group VIB metal, followed by aging, drying and calcining. The catalyst is useful for promoting a number of hydrocarbon conversion reactions, particularly those involving hydrogenative desulfurization.
