Electrochemical production of carbon monoxide and valuable products

A method of producing valuable products comprising:

• (a) providing two electrochemical reactors each having an anode, a cathode, and a mixed-conducting membrane between the anode and the cathode, wherein both the anode and the cathode comprise Ni;
• (b) introducing a fuel stream to each of the anodes;
• (c) introducing a CO2-containing stream to a first cathode and introducing a H2O-containing stream to a second cathode, wherein the first cathode produces a first cathode exhaust stream and the second cathode produces a second cathode exhaust stream, wherein the CO2-containing stream introduced to the first cathode also comprises carbon monoxide, wherein the carbon monoxide is less than the carbon dioxide;
• wherein carbon monoxide is generated from carbon dioxide electrochemically and hydrogen is generated from water electrochemically;
• wherein neither reactor generates electricity or receives electricity.
