Patent ID: 7828878

Claim:
A process for the separation of a selectively adsorbable component from a gas mixture comprising such selectively adsorbable component and at least one less selectively adsorbable product component, wherein the process uses at least one adsorbent bed containing adsorbent material, the ratio of bed length (L) to mean particle diameter squared of the adsorbent material (d p 2 ) is greater than or equal to 5 mm −1 and less than or equal to 10,000 mm −1 , and said process comprises the steps of: (a) adsorption of said selectively adsorbable component from said gas mixture onto said at least one adsorbent bed; (b) recovery of said at least one less selectively adsorbable product component from said gas mixture, wherein the recovery is at least 50%; and (c) desorption of said selectively adsorbable component from said at least one adsorbent bed; wherein the cycle frequency is greater than 0.25 Hz.
