Adsorption process for oxygen removal using a multi-layered adsorbent bed.

摘要

A process is set forth for removing oxygen from an oxygen-containing feed stream comprising passing the oxygen-containing stream through a multi-layered adsorption bed comprising a kinetic based oxygen-selective adsorbent at the feed end of the bed and an equilibrium based oxygen-selective adsorbent at the product end of the bed wherein regeneration of the bed includes a "hybrid repressurization" scheme which involves simultaneously repressurizing the bed with a portion of both the product stream and the feed stream.
