ABSTRACT:
Hydroprocessing of hydrocarbon oils is carried out utilizing a catalyst containing nickel and tungsten active metal components on a porous support material 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 useful for promoting the conversion of asphaltenes contained in hydrocarbon oils, especially in the second reaction zone of a multiple-stage hydrodesulfurization process wherein demetallization catalysts are employed in upstream reaction zones.
