A process is described for simultaneously hydrodesulfurizing, hydrodenitrogenating and mild hydrocracking a hydrocarbon feedstock comprising nitrogen components, sulfur components and feed components boiling above 700/sup 0/F comprising contacting the feedstock under conditions of elevated temperature and a hydrogen partial pressure less than about 1,500 p.s.i.g. with a particulate catalyst comprising at least one nickel active metal hydrogenation component, at least one molybdenum active metal hydrogenation component and at least one phosphorus component on a support comprising an amorphous porous refractory oxide, the catalyst having a pore size distribution wherein the mode pore diameter is in the range from about 55 to about 100 angstroms and at least about 75 percent of the pore volume is in pores of diameter in the range from about 50 angstroms to about 130 angstroms and from about 20 angstroms above the mode pore diameter to about 20 angstroms below the mode pore diameter and less than 10 percent of the pore volume is in pores of diameter greater than 110 angstroms. The conditions are such that the sulfur components and the nitrogen components in the feedstock are converted to product components of reduced sulfur and nitrogen content and between about 10 and 50 volume percent of the feed components boiling above 700/sup 0/F are simultaneously converted to product components boiling at or below 700/sup 0/F.
