ABSTRACT:
A catalyst useful for hydroprocessing a hydrocarbon-containing oil contains at least one hydrogenation component on an amorphous, porous refractory oxide support containing between 2 and 8 weight percent of silica. The catalyst is prepared by impregnating support particles having a narrow pore size distribution and a median pore diameter greater than about 120 angstroms with a solution containing precursors of the hydrogenation components, followed by drying and calcining. The catalyst is useful for promoting a number of hydrocarbon hydroprocessing reactions, particularly simultaneous hydrogenative desulfurization, demetallization and denitrogenation of residuum-containing oils.
