摘要：

A dense membrane of perovskite Ba0.5Sr0.5Co0.8Fe0.2O3-delta has been successfully prepared by polymerized complex method. Oxygen permeation according to carbon dioxide concentrations was measured in the oxygen partial pressure range of 2.1 x 10(-3) similar to 0.63 atm and phase stability of membrane were examined using SEM-EDS. The oxygen flux increased with increasing temperature and pressure difference and the maximum oxygen permeation flux through 1.0 mm membrane was ca. 3.7 ml/cm(2).min at 950 degrees C. The oxygen permeation in the condition of air and CO2 (300 similar to 700 ppm) in feed stream decreased more than 43% in comparison with air feed stream. (C) 2008 Elsevier Ltd. All rights reserved
