ABSTRACT:
A process for removing the impurities carbon monoxide, carbon dioxide, water vapor and, optionally, hydrogen from a feed stream comprising initially removing water and carbon dioxide, oxidizing carbon monoxide and hydrogen to form carbon dioxide and water vapor, respectively, and removing the oxidation products. The process may be conducted batchwise or continuously by carrying out purification in a plurality of treatment zones wherein one or more zones are being regenerated while one or more others are purifying the feed stream.
