ABSTRACT:
The invention is a process for recovering oxygen from an oxygen-containing gaseous mixture containing one or more components selected from water, carbon dioxide or a volatile hydrocarbon which process utilizes ion transport membranes comprising a multicomponent metallic oxide containing barium. The process utilizes a temperature regime which overcomes problems associated with degradation of barium-containing multicomponent oxides caused by carbon dioxide.
