Patent ID: 8123933

Claim:
A process for converting heavy hydrocarbon feed into lighter hydrocarbon products comprising: mixing said heavy hydrocarbon liquid feed with catalyst particles and hydrogen to form a heavy hydrocarbon slurry comprising hydrocarbon liquid and catalyst particles, said catalyst particles comprising about 2 to about 45 wt-% iron oxide and about 20 to about 98 wt-% alumina; hydrocracking hydrocarbons in said heavy hydrocarbon slurry in the presence of hydrogen and catalyst particles in a hydrocracking reactor to produce a hydrocracked slurry product comprising lighter hydrocarbon products, said reactor comprising no less than about 0.1 and no more than about 1.5 wt-% iron content based on the total weight of non-gas materials in the reactor; and withdrawing said hydrocracked slurry product from said hydrocracking reactor.
