BSCF TUBULAR MEMBRANE COATED WITH BARIUM-CHROME BASED OXIDE FOR OXYGEN SEPARATION AND FABRICATING METHOD THEREOF

摘要

The present invention provides a perovskite-type ion conductive oxygen membrane having a composition of Ba_1-xSr_xCo_1-yFe_yO_3-δcoated with barium chromium oxide, a producing method thereof, and an oxygen separation process using the membrane. The membrane coated with barium chromate based oxide of the present invention has a significantly improved oxygen permeability and thermal stability compared with an uncoated separation membrane, thereby being usefully applied in separating oxygen from air containing carbon dioxide and the like.
