Abstract (en)
[origin: WO2018228716A1] The invention relates to a method (100-500) for producing a gas product containing at least carbon monoxide, in which method at least carbon dioxide is subjected to an electrolysis process (10) in order to obtain a raw gas (A) containing at least carbon monoxide and carbon dioxide and the carbon dioxide contained in the raw gas (A) is partially or completely fed back to the electrolysis process (10). According to the invention, the raw gas (A) is partially or completely subjected to a membrane separation process (20) in order to obtain a retentate mixture (B) and a permeate mixture (C), which is enriched in carbon dioxide in comparison with the raw gas (A), and that the retentate mixture (B) is partially or completely subjected to a pressure swing adsorption process (40) in order to obtain the gas product (D), which is enriched in carbon monoxide and depleted of carbon dioxide in comparison with the retentate mixture (B), and a residual mixture (E), which is depleted of carbon monoxide and enriched in carbon dioxide in comparison with the retentate mixture (B). The invention further relates to a corresponding system.
