Abstract
A catalyst useful for hydroprocessing a hydrocarbon-containing oil contains at least one hydrogenation component on an amorphous, porous refractory oxide. The catalyst is prepared by impregnating support particles having a narrow pore size distribution and a mode pore diameter from about 70 to 80 angstroms with a solution containing a precursor of the hydrogenation components, followed by drying and calcining. The catalyst is useful for promoting a number of hydrocarbon hydroprocessing reactions, particularly hydrogenative desulfurization, dedemetallization and denitrogenation, and most particularyl, hydrodesulfurization of residuum-containing oils.
