This patent describes a catalyst prepared by a method comprising the steps of impregnating support particles with an aqueous impregnant solution comprising a dissolved Group VIB metal component, a dissolved Group VIII metal component and a dissolved phosphorus component, the aqueous impregnant solution containing about 1 to about 6 weight percent of the phosphorus component, calculated as P, the supported comprising a narrow pore size distribution including at least about 60 percent of the total pore volume in pores of diameter from about 60 of the total pore volume in pores of diameter from about 60 to about 100 angstroms, having a mode pore diameter in the range from about 60 to about 90 angstroms and at least about 40 percent of the total pore volume in pores of diameter between the mode pore diameter and less than about 40 angstroms above the mode pore diameter. The second step consists of calcining the impregnated support particles to produce a catalyst having 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 and less than 10 percent of the total pore volume in pores of diameter greater than 130 diameter angstroms, having a mode pore diameter n the range from about 75 to about 110 angstroms and at least about 40 percent of the total pore volume in pores of diameter between the mode pore diameter and less than about 90 angstroms above the mode pore diameter.
