Hydrocarbon feedstocks are hydrocracked by contacting the feedstock in the presence of hydrogen and under hydrocracking reaction conditions with a catalyst comprised of a metal fluoride, the metal being boron, tantalum, niobium or mixtures thereof, a fluoride containing Bronsted acid and a Group VIII noble metal hydrogenation component, the Bronsted acid being present in at least an equi-molar amount relative to the metal fluoride and sufficient to dissolve at least a portion of the metal fluoride. The presence of the noble metal hydrogenation component serves to extend the hydrocracking catalyst life of the metal fluoride and fluoride containing Bronsted acid. The catalyst can be described as a slurry or dispersion composed of a solid noble metal on a support in a liquid phase acid system.
A hydrocracking process which comprises contacting a hydrocarbon feedstock which has an initial boiling point of at least about 215.degree. C. with hydrogen, under hydrocracking conditions, and with a substantially liquid phase acid catalyst comprised of:
A hydrocracking process which comprises contacting a hydrocarbon feedstock having an initial boiling point of at least about 215.degree. C. with hydrogen, at temperatures ranging from about 20.degree.-300.degree. C., and with a substantially liquid phase acid catalyst comprised of:
