Abstract
A cyclic process for the separation of water and carbon dioxide contaminants from a feed gas stream by adsorption on molecular sieve adsorbents and the subsequent regeneration of the adsorbents is disclosed. Adsorption of the water and CO.sub.2 contaminants is accomplished by passing the feed gas stream through first and second adsorbent zones, containing molecular sieve adsorbents. Water is adsorbed in the first zone and the carbon dioxide is adsorbed primarily in the second zone. Regeneration of the adsorbent zones is accomplished by the sequential steps of:
