ABSTRACT:
An oxygen selective adsorbent and a method for making an oxygen selective adsorbent wherein a porous carbon substrate such as a carbon molecular sieve, activated carbon, carbon black, coal, or petroleum coke, is impregnated with a solution of an acidic species and the impregnated substrate is dried. The oxygen selective adsorbent can be used in a pressure swing adsorption process for the separation of oxygen from nitrogen, for example, in air.
