【Abstract】 Perovskite Ba 0 5 Sr 0 5 Co 0 8 Fe 0 2 O 3- δ oxide is a novel stable oxygen permeable material, which can transfer oxygen by lattice oxygen and electrons. The membrane reactor made of perovskite Ba 0 5 Sr 0 5 Co 0 8 Fe 0 2 O 3- δ was applied to propane oxidative dehydrogenation (PODH), and it was found that the membrane material can increase the conversion of propane and the selectivity for propylene in the PODH reaction. At the same time, the PODH reaction can promote formation of more oxygen defects in the material and increase the oxygen permeability of the membrane at high temperature.
