A method for treating products from a CO2 electrolysis process where carbon dioxide (CO2) and water (H2O) are electrochemically reacted in a cathode chamber of an electrolysis cell. Gaseous cathode products are formed which comprise ethylene (C2H4), hydrogen (H2) and carbon monoxide (CO). The products are treated in a multi-stage separating process.

Next, the product gas stream is compressed to a pressure, and then the compressed product gas stream is fed to a gas permeation process, wherein hydrogen (H2) is separated off by passing the hydrogen through a hydrogen-permeable membrane. Next, the retentate which remains and which comprises ethylene (C2H4) and carbon monoxide (CO) is subjected to distillative separation, such that ethylene (C2H4) and carbon monoxide (CO) are separated.
