John W Armond: Process for the separation of a gaseous mixture. BOC, David L Rae, Larry R Cassett, September 7, 1982: US04348213 (42 worldwide citation)

In a gas separation process a pressurized gaseous mixture is passed through a first bed of adsorbent while a second bed is being regenerated by desorbing gas therefrom and venting or discharging such gas from the second bed. The adsorbent is of such a character that one component of the gaseous mixt ...
