Abstract
Abstract A catalyst composite comprising a metal of Group VIB and Group VIII and from about 1 to about 5 weight percent boron phosphate composited with a refractory inorganic oxide and characterized by a pore volume of at least about 0.4 cc. per gram in the 100-500 A. range. The catalyst composite is particularly useful for hydrorefining petroleum crude oils and residual crude oils.
