Beaton, W I; Hensley, A L; Evans, A J

A catalyst for the hydrodemetallation, hydrodesulfurization, and hydrocracking of a hydrocarbon feedstock containing asphaltenes, metals, and Shell hot filtration solids precursors and the conversion of at least 30 vol. % of the feedstock fraction boiling over 1,000/sup 0/F to material boiling below 1,000/sup 0/F in at least one ebullated bed reaction zone with hydrogen is described. The catalyst comprises a Group VIB metal component and a cobalt component on a porous inorganic oxide support, wherein the Group VIB metal is present in an amount ranging from about 3.5 to about 5.0 wt. % calculated as an oxide and based on total catalyst weight. The cobalt is present in an amount ranging from about 0.4 to about 0.8 wt. % calculated as an oxide and based on total catalyst weight, and the catalyst has a surface area of about 150 to about 220 m/sup 2//gm, a total pore volume of about 0.85 to about 1.5 cc/gm, and a pore volume in pores having diameters larger than 1,200 angstroms of about 0.15 to about 0.4 cc/gm.
