Abstract
Disclosed herein are rapid cycle pressure swing adsorption (PSA) process for separating Ofrom Nand/or Ar. The processes use a carbon molecular sieve (CMS) adsorbent having an O/Nand/or O/Ar kinetic selectivity of at least 5 and an Oadsorption rate (1/s) of at least 0.2000 as determined by linear driving force model at 1 atma and 86° F.
