摘要: Oxygen is removed from gas streams by subjecting the stream to a pressure swing adsorption process carried out at temperature in range of 300 1400° C. using as adsorbent perovskite material having structural formula A 1-x M x BO 3- δ, where rare earth ion, Na, Ca, Sr, Ba or mixtures these, B Co, Mn, Cr Fe, varies 0.1 1 and δ deviation stoichiometric composition resulting substitution Ca for ions.
