Process and system for producing liquid fuel from carbon dioxide and water

A system for production of liquid fuel from carbon dioxide and water using electricity, the system comprising:

• (a) a purification unit in fluid communication with stack gas units of industrial plants and/or power plants, said purification unit arranged and designed to separate the carbon dioxide from stack gases;
• (b) an electrolysis unit arranged to convert water into hydrogen and oxygen;
• (c) a first mixing unit disposed downstream of and in fluid communication with said purification unit and said electrolysis unit to mix said carbon dioxide and said hydrogen;
• (d) a catalytic reactor disposed downstream of and in fluid communication with the said first mixing unit to receive the mixture of said carbon dioxide and said hydrogen and to produce methanol and carbon monoxide and said water;
• (e) a second mixing unit disposed downstream of and in fluid communication with the said catalytic reactor, said second mixing unit arranged and designed to accept a portion of said carbon monoxide;
• (f) a liquid fuel generation unit disposed downstream of and in fluid communication with said second mixing unit, said liquid fuel generation unit arranged and designed to receive and convert a portion of said carbon monoxide in the presence of a substantially pure hydrogen gas to produce said liquid fuel;
• and
• (g) an oxidation unit disposed downstream of and in fluid communication with said liquid fuel generation unit, said oxidation unit arranged and designed to oxidize any unaccepted portion of separated hydrocarbon product under conditions producing a combustion product comprising said hydrogen, said carbon monoxide, said carbon dioxide and said water.
