Patent ID: 8691881

Claim:
A process for producing a liquid chemical or liquid fuel product wherein CO 2 emissions are minimized, the process comprising the steps of: (i) endothermically gasifying a carbon-containing feedstock with an oxygen-containing gas and a carbon-containing co-feed substance to form a synthesis gas, wherein the carbon-containing co-feed substance is a substance which lies in a region bound by points CH 2 —H 2 O—H 2 on a C—H—O ternary phase diagram; (ii) in the same vessel as the gasification reaction, exothermically reacting the synthesis gas to form dimethyl ether or a Fisher-Tropsch fuel product; and (i) recycling any CO2 within theprocess; wherein the use of the carbon-containing co-feed reduces the production of CO 2 in the process.
