A dense Ba0.5Sr0.5Co0.8Fe0.2O3-delta membrane tube was prepared by the extruding method. Furthermore, a membrane reactor with this tubular membrane was successfully applied to partial oxidation of methane (POM) reaction, in which the separation of oxygen from air and the partial oxidation of methane are integrated in one process. At 875degreesC, 94% of methane conversion, 98% of CO selectivity, 95% of H-2 selectivity, and as high as 8.8 mL/(min (.) cm(2)) of oxygen flux were obtained. In POM reaction condition. the membrane tube shows a very good stability.
