Ward, J W

A catalytic process is described wherein a hydrocarbon oil containing asphaltenes and less than 50 ppmw of contaminant metals is contacted under conditions of elevated temperature and pressure with a catalyst comprising nickel and tungsten active metal components on a porous support material comprising gamma alumina. The catalyst has at least about 60 percent of the total pore volume distributed in pores of diameter from about 180 to about 240 angstroms, with essentially all pores being of diameter greater than about 100 angstroms, and with less than about 10 percent of the total pore volume being in pores of diameter greater than 300 angstroms. The catalyst has a surface area greater than about 100 m/sup 2//gram, and the effluent hydrocarbon oil contains less asphaltenes than the hydrocarbon oil.
