摘要： Methods for simultaneous syngas generation by opposite sides of a solid oxide co-electrolysis cell are provided. The method can comprise exposing a cathode side of the solid oxide co-electrolysis cell to a cathode-side feed stream; supplying electricity to the solid oxide co-electrolysis cell such that the cathode side produces a product stream comprising hydrogen gas and carbon monoxide gas while supplying oxygen ions to an anode side of the solid oxide co-electrolysis cell; and exposing the anode side of the solid oxide co-electrolysis cell to an anode-side feed stream. The cathode-side feed stream comprises water and carbon dioxide, and the anode-side feed stream comprises methane gas such that the methane gas reacts with the oxygen ions to produce hydrogen and carbon monoxide. The cathode-side feed stream can further comprise nitrogen, hydrogen, or a mixture thereof.

摘要： A syngas generation system that combines a solid oxide electrolysis cell (SOEC) and a carbon gasification unit is described. On the cathode side of the SOEC, CO2 and H2O are electrochemically converted to syngas. At the anode side of the system, a second stream of syngas is produced through a carbon gasification process in which solid carbon is reacted with H2O/CO2. Oxygen ion transported across the SOEC electrolyte reacts at the anode with a portion of the syngas produced in the gasification process. This reaction product (H2O/CO2) can be fed back to the gasification unit.
