Abstract:
1. A process for production of a liquid fuel from carbon dioxide and water using electricity, comprising: (a) capturing carbon dioxide from a concentrated carbon dioxide stream within a mixed industrial gas stream; (b) purifying said concentrated carbon dioxide by separating other constituents from said mixed industrial gas stream; (c) providing water and electricity and electrolyzing the water into hydrogen and oxygen; (d) reacting a mixture of purified carbon dioxide from step (b) and hydrogen in the presence of a catalyst to produce methanol, carbon monoxide, water, and at least one hydrocarbon byproduct wherein heat is generated and controlled by increasing the relative amount of said carbon monoxide to increase said heat and/or by adding said carbon dioxide to decrease said heat; (e) reacting methanol and a mixture of said carbon monoxide and unreacted hydrogen from step (d) in at least one step to obtain said liquid fuel; and (f) reacting oxygen from step (c) and said at least one hydrocarbon byproduct to produce additional carbon monoxide and hydrogen for increased production of said liquid fuel.
