Method and device for the electrochemical utilization of carbon dioxide

The invention relates to a method and to a device for the electrochemical utilization of carbon dioxide. In an electrolytic cell of an electrolyzer, the carbon dioxide is thereby reduced to a product gas. The product gas comprising carbon dioxide is then passed to a gas scrubber device. There, the p...

Zusammenfassung:	The invention relates to a method and to a device for the electrochemical utilization of carbon dioxide. In an electrolytic cell of an electrolyzer, the carbon dioxide is thereby reduced to a product gas. The product gas comprising carbon dioxide is then passed to a gas scrubber device. There, the product gas of carbon dioxide is scrubbed by means of an absorbent. The absorbent is subsequently regenerated in a cell of an electrodialyzer of an electrodialysis unit. The regenerated absorbent is then at least partially returned to the gas scrubber device. The carbon dioxide released during the regeneration is at least partially returned into the electrolyzer as educt gas.
