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.
