HYBRID CO2 CAPTURE and ELECTROLYSIS

A system contains a CO2 purifier and a CO2 electrolyzer. In operation, the CO2 purifier selectively captures CO2 from a gas stream and then releases purified CO2 as an output. The purified CO2 is then provided as an input to the cathode of the CO2 electrolyzer. The CO2 electrolyzer can electrochemic...

More Information
Summary:A system contains a CO2 purifier and a CO2 electrolyzer. In operation, the CO2 purifier selectively captures CO2 from a gas stream and then releases purified CO2 as an output. The purified CO2 is then provided as an input to the cathode of the CO2 electrolyzer. The CO2 electrolyzer can electrochemically reduce the CO2 to a carbon-containing product (CCP) that may be stored, consumed, used to synthesize a valuable product, etc. The purifier may be an electrochemical cell that allows at least some non-CO2 inlet components to pass without being absorbed. Depending on the composition of the inlet stream, examples of non-absorbed components include water, nitrogen, carbon monoxide, oxygen, and sulfur-containing compounds.
