Hydrocarbon conversion catalysts contain at least one Group VIB metal component, at least one Group VIII metal component, and a phosphorus component on a porous refractory oxide and have a narrow pore size distribution including at least about 75 percent of the total pore volume in pores of diameter

Hydrocarbon conversion catalysts contain at least one Group VIB metal component, at least one Group VIII metal component, and a phosphorus component on a porous refractory oxide and have a narrow pore size distribution including at least about 75 percent of the total pore volume in pores of diameter from about 70 to about 130 angstroms. The catalyst is useful for promoting a number of hydrocarbon conversion reactions, particularly those involving hydrogenative desulfurization.
