Abstract
A process for hydrodemetallation and hydrodesulfurization of hydrocarbon feedstock containing asphaltenes and metals by contacting said feedstock with hydrogen and a bimodal catalyst consisting essentially of at least one active original hydrogenation metal selected from Group VIB deposited on a support comprising alumina wherein said catalyst has a surface area within the range of about 140 to about 300 m.sup.2 /gm, a total pore volume based upon measurement by mercury penetration within the range of about 0.4 cc/gm to about 1.0 cc/gm, and comprising about 60% to about 95% of its micropore volume in micropores having diameters within the range of about 50 A to about 200 A, 0% to about 15% of its micropore volume in pores having diameters within the range of about 200 A to about 600 A and about 3% to about 30% of said total pore volume based upon measurements by mercury penetration in macropores having diameters of 600 A or greater.
