Patent ID: 8491780

Claim:
A method for hydroprocessing a biocomponent feedstock, comprising: treating an off-gas stream from a fluid catalytic cracking reactor to remove hydrogen sulfide and carbon dioxide, the treated off-gas stream having a hydrogen content of not more than 25%; and hydroprocessing a feedstock comprising a biocomponent portion in a reactor in the presence of the treated off-gas stream, a catalyst with hydrogenation activity, and steam under effective hydroprocessing conditions to produce a vapor effluent, an aqueous effluent, and a diesel boiling range product; wherein the effective hydroprocessing conditions include an LHSV from about 0.5 hr −1 to 1.5 hr −1 , a temperature from about 600° F. to about 650° F. (about 316° C. to about 343° C.), and a hydrogen partial pressure from about 15 psig to about 200 psig (about 103 kPag to about 1.4 MPag).
