Patent ID: 7264651

Claim:
A swing adsorption process for the separation of at least one more readily adsorbable component of a feed gas mixture containing said component and at least one less readily adsorbable component, in a cyclic adsorption/desorption sequence comprising: (a) positioning a regenerator material section in an adsorbent bed contained in at least one adsorption vessel wherein said regenerator material section is placed downstream of a water adsorption zone in the adsorbent bed; (b) passing the feed gas mixture to a feed end of said at least one adsorption vessel and through the adsorbent bed containing at least one adsorbent material and said regenerator material section, said adsorbent material being capable of selectively adsorbing the at least one readily adsorbable component of the feed gas mixture and said regenerator material section being capable of reducing any temperature rise in the adsorbent material downstream of the regenerator material section; and (c) withdrawing the at least one less readily adsorbable component from a withdrawer end of the at least one adsorption vessel; wherein the regenerator material is an encapsulated phase change material.
