Abstract
A process is set forth for the production of a carbon monoxide stream from a feed stream comprising carbon monoxide, hydrogen, carbon dioxide, methane, nitrogen and moisture. The process comprises contacting the feed stream at elevated pressure with a layered adsorbent bed comprising (i) a pretreatment adsorbent in order to adsorb moisture preferentially over methane, nitrogen and carbon dioxide and (ii) a main adsorbent in order to adsorb carbon monoxide preferentially over hydrogen, carbon dioxide, methane and nitrogen. A key to the present invention is that a carbon-based adsorbent is used as the pretreatment adsorbent.
