Abstract (en)
[origin: WO2018228718A1] The invention relates to a method (100, 200) for producing a gas product (D) 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), characterized in that the raw gas (A) is partially or completely subjected to an adsorption process (20) in order to obtain the gas product (D), which is enriched in carbon monoxide and depleted of carbon dioxide in comparison with the raw gas (A), and a residual mixture (E), which is depleted of carbon monoxide and enriched in carbon dioxide in comparison with the raw gas (A), and that the residual mixture (E) is at least partially subjected to a membrane separation process (30) in order to obtain a first gas mixture (B) as a retentate and a second gas mixture (H) as a permeate, the first gas mixture (B) at least partially being fed back to the adsorption process (20) together with the raw gas (A) or with the portion thereof subjected to the adsorption process (20), and the second gas mixture (H) at least partially being fed back to the electrolysis process (10). The invention further relates to a corresponding system.
