Hydroprocessing of hydrocarbon oils is carried out utilizing a catalyst containing active metal components on a porous refractory oxide and having a narrow pore size distribution, with essentially all pores being of diameter greater than about 100 angstroms, with less than about 10 percent of the total pore volume being in pores of diameter greater than 300 angstroms, and with at least about 60 percent of the total pore volume being in pores of diameter from about 180 to about 240 angstroms. The catalyst is particularly useful for removing of contaminant metals from residuum hydrocarbon oils.
