초록

The invention comprises a pressure swing adsorption process for the separation of a less adsorbable component from a mixture comprising the less adsorbable component and a more adsorbable component, the process comprising a cyclic adsorption/desorption process wherein the desorption step is at a selected pressure and occurs for a selected time such that a pressure reducing apparatus utilized to evacuate the gas does not require extraneous cooling.

청구항

[ We claim:] [1.] A two-bed pressure swing adsorption process for the separation of a less adsorbable component from a gas mixture comprising said less adsorbable component and a more adsorbable component, said process comprising an adsorption/desorption cycle having the following steps:a) introducing said gas mixture into a feed end of a vessel which contains a bed of material capable of selectively adsorbing said more adsorbable component, whereby pressure in said vessel increases;b) an adsorption step comprising adsorbing at least a portion of said mo...
