Patent ID: 8277638

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, said catalyst particles comprising 2 to 45wt-% iron oxide and 20 to 98 wt-% alumina; hydrocracking hydrocarbons in said heavy hydrocarbon slurry in the presence of hydrogen, catalyst particles and 0 to 1 wt-% sulfur relative to the feed and catalyst particles in a hydrocracking reactor to produce a liquid hydrocracked slurry product comprising lighter hydrocarbon products, said liquid hydrocracked slurry product having an API gravity of 4 times that of the heavy hydrocarbon feed; and withdrawing said liquid hydrocracked slurry product from said hydrocracking reactor.
