A mixed ionic and electronic conducting dual-phase oxygen permeable membrane with high CO2 tolerance

Abstract

Dual-phase membranes have been successfully developed using x wt% Ce0.9La0.1O2−δ and 100 − x wt% La2CuO4+δ (xCLO-(100 − x)LCO) with no alkaline earth metals contained in the system. The 60CLO-40LCO dual-phase membrane exhibits the highest oxygen permeation rate of 0.25 mL min−1 cm−2 under He sweep gas conditions at 950 °C. Additionally, excellent CO2 tolerance was obtained using this sample. Its stable oxygen permeability and outstanding CO2 tolerance performance make the 60CLO-40LCO dual-phase membrane highly promising in the oxyfuel technologies for the CO2 capture and sequestration application.
