Abstract
A process for producing and purifying a synthesis gas stream that contains CO- and H-produced from a hydrocarbon-containing feed in a gas production unit. COis separated from the synthesis gas stream and CO is cryogenically separated from the synthesis gas stream. COthat 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 COis 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 COis heated by indirect heat transfer from the heat transfer medium to the adsorbent to effect desorption of CO.
