Patent ID: 8592492

Claim:
A method, comprising (A) providing fossil-fuel hydrocarbon feed; (B) forming from said fossil-fuel hydrocarbon feed a gaseous product stream comprising hydrogen and carbon monoxide at a mole ratio of H 2 :CO of at least 2.0:1; (C) forming a syngas stream that is derived from carbonaceous feed material and subjecting this syngas stream to partial oxidation; (D) adding the gaseous product stream formed in step (B) to a the partially oxidized syngas stream derived from carbonaceous feed material, in a sufficient amount to form a mixed syngas stream having a H 2 :CO mole ratio greater than that of said partially oxidized syngas stream derived from carbonaceous feed material; (E) converting said mixed syngas stream to form product fuel and recovering from said converting a byproduct stream comprising one or more of hydrogen, CO, water vapor, methane, and hydrocarbons containing 2 to 8 carbon atoms and 0 to 2 oxygen atoms; and (F) reacting up to 100% of said byproduct stream in said formation of said gaseous product stream in step (B).
