Abstract
Heavy mineral oil fractions are selectively hydrocracked to produce mainly middle distillate oils boiling in the 300.degree.-700.degree. F range. Certain novel, highly active and selective catalysts are utilized comprising molybdenum and/or tungsten plus nickel and/or cobalt supported upon certain heterogeneous composites of a silica-alumina cogel or copolymer dispersed in a matrix consisting essentially of alumina gel.
Claims5
A hydrocracking catalyst composition comprising a molybdenum and/or tungsten first component plus a nickel and/or cobalt second component supported on a heterogeneous support comprising 10-50 weight-percent of a cracking component consisting essentially of a finely divided silica-alumina cogel or copolymer containing about 50-90 weight-percent of SiO.sub.2, said cracking component being dispersed in a matrix consisting essentially of alumina.
