Abstract

Among novel technologies under development as cost-effective alternatives to conventional oxygen production methods, mixed ionic?electronic conducting ceramic membranes offer great promise. These oxygen-transport membranes selectively separate oxygen from an air supply, or other source, at elevated temperature (700°-1000°C) under an oxygen chemical potential gradient. Besides direct use in schemes for oxygen production, the membranes have attracted much interest for the conversion of natural gas into synthesis gas (CO + H₂). A discussion on the oxygen transport properties, oxygen stoichiometry, and phase stability of SrCo_0.8Fe_0.2O_3-d and Ba_0.5Sr_0.5Co_0.8Fe_0.2O_3-d, and related compositions covers the influence of CO₂ adsorption on the kinetics of surface oxygen exchange, chemical expansion, and the phenomenon of kinetic demixing; and prospects to use these materials as oxygen transport membranes. This is an abstract of a paper presented at the 2006 AIChE National Meeting (San Francisco, CA 11/12-17/2006).
