Abstract
Abstract A process for hydroprocessing a hydrocarbonaceous feedstock containing constituents boiling above 350° C. comprises contacting said feedstock with hydrogen under hydroprocessing conditions with a catalyst composition comprising a rigidly interconnected pack containing inorganic matrix oxide and about 10-95% fluid catalytic cracking catalyst microspheroids, based upon the total weight of said matrix oxide and said microspheroids, said pack characterized by a pore volume of at least 0.15 cc. per cc., at least about 30% of said pore volume present as pores having diameters within the range of 50-250 Angstroms and at least about 5% of said pore volume present as pores having diameters greater than 1,000 Angstroms.
