A method for producing a product mixture (3a, 3b) is specified which comprises a carbon-containing fuel, - wherein the carbon-containing fuel is generated by electrolysis of carbon dioxide in an electrolyser (5) which comprises a catholyte space (11) and an anolyte space (21), - wherein a hydrogen carbonate- and / or carbonate-containing catholyte (12) flows through the catholyte space (11) at a cell pressure p k of at least 1.5 bar, - the catholyte (12) flowing out of the catholyte space (11) then being passed through a desorber (42) at a desorption pressure p d which is lower than the cell pressure and is circulated back into the catholyte space (11) from the desorber (42) , - The catholyte (12) in the desorber (42) being heated to a temperature T d which is higher than that of the catholyte space (11), so that physically and / or chemically dissolved carbon dioxide is desorbed from the catholyte (12). A device (1) for carrying out such a method is also specified. |
