Abstract: A process for producing and purifying a synthesis gas stream that contains CO- and H2-produced from a hydrocarbon-containing feed in a gas production unit. CO2 is separated from the synthesis gas stream and CO is cryogenically separated from the synthesis gas stream. CO2 that makes up 5% to 30% by volume in the synthesis is reduced to less than 10 ppm by volume by temperature swing adsorption. The temperature swing adsorption takes place upstream of the cryogenic separation of CO. The CO2 is adsorbed using a disordered adsorbent bed wherein the adsorbent is cooled by means of indirect heat transfer from the adsorbent to the heat transfer medium during adsorption and the adsorbent loaded with CO2 is heated by indirect heat transfer from the heat transfer medium to the adsorbent to effect desorption of CO2.

Abstract: The invention relates to a process and device for the cryogenic separation of a methane-containing feed gas predominantly consisting of hydrogen and carbon monoxide, that is partially condensed in this case by cooling, in order to obtain a hydrogen-containing first liquid phase predominantly consisting of carbon monoxide and methane, from which first liquid phase, in an H2 separation column that is heated via a circulation heater, a second liquid phase is generated by separating off hydrogen, from which second liquid phase, in a CO/CH4 separation column, a carbon monoxide-rich gas phase is obtained having a purity that permits release thereof as carbon monoxide product. It is characteristic in this case that a low-methane material stream is withdrawn from the H2 separation column and is then applied to the CO/CH4 separation column as reflux.
