Abstract
A process and apparatus is disclosed for converting heavy hydrocarbon feed into lighter hydrocarbon products. The heavy hydrocarbon feed is slurried with a catalyst comprising iron oxide and alumina to form a heavy hydrocarbon slurry and hydrocracked to produce lighter hydrocarbons. The iron oxide in the catalyst converts to catalytically active iron sulfide in the presence of hydrogen and sulfur.
Claims17
A process for converting heavy hydrocarbon feed into lighter hydrocarbon products comprising:
- mixing said heavy hydrocarbon liquid feed with hydrogen and catalyst particles comprising 2 to 45 wt-% iron oxide and 20 to 98 wt-% alumina to form a heavy hydrocarbon slurry on a non-volatile basis;
- heating the slurry to a temperature of at least 410° C. in the presence of sulfur;
- converting essentially all of said iron oxide in the hydrocarbon slurry to iron sulfide upon reaching said temperature of no more than 410° C.;
- hydrocracking hydrocarbons in said heavy hydrocarbon slurry in the presence of hydrogen and iron sulfide in a hydrocracking reactor to produce a hydrocracked slurry product comprising lighter hydrocarbon products;
- and
- withdrawing said hydrocracked slurry product from said hydrocracking reactor.
