CH₄-CO₂-O₂ reforming to syngas in a novel Ba_0.5Sr_0.5Co_0.8Fe_0.2O_3-δ oxygen-permeable membrane reactor using LiLaNiO/γ-Al₂O₃ as catalyst was successfully reported. Excellent reaction performance was achieved with around 92% methane conversion efficiency, 95% CO₂ conversion rate, and nearly 8.5mL/min·cm² oxygen permeation flux. In contrast to the oxygen permeation model with the presence of large concentration of CO₂ (under such condition the oxygen permeation flux deteriorates with time), the oxygen permeation flux is really stable under the CH₄-CO₂-O₂ reforming condition.
