By respectively sending methane and the mixture of air and water to the opposite sides of Ce_0.8Sm_0.2O_2-δ-Sr₂Fe_1.5Mo_0.5O_5+δ (CSO-SFMO) dual-phase oxygen-permeable membrane reactor, co-production of two synthesis gases H₂/N₂ and H₂/CO were achieved in this work. A porous layer with the same material as the bulk membrane was deposited on the surface of CSO-SFMO membrane to catalyze surface reactions. It was found that CSO with fluorite structure and SFMO with perovskite structure show good chemical compatibility even after being sintered at high temperature. Moreover, the CSO-SFMO dual phase membrane with porous layer exhibits high oxygen permeability and good CO₂ tolerance under harsh conditions. Using CSO-SFMO dual phase membrane as reactor, a suitable H₂/N₂ ratio of 3 and H₂/CO ratio of 2 was obtained on the opposite sides of the membrane. Meanwhile, CO selectivity of 98%, CH₄ conversion of 97% in the methane side and synthesis gas (H₂ + N₂) production rate of 3.0 cm³ min⁻¹ cm⁻² on the feed side were achieved at 900 °C.

通过将甲烷以及空气和水的混合物分别输送到Ce _0.8 Sm _0.2 O2 _-δ- Sr ₂ Fe _1.5 Mo _0.5 O _{5 +δ}（CSO-SFMO）双相透氧膜反应器的相对侧，生成两种合成气H ₂ / N ₂和H ₂/ CO在这项工作中得以实现。在CSO-SFMO膜的表面上沉积与主体膜具有相同材料的多孔层，以催化表面反应。发现即使在高温下烧结，具有萤石结构的CSO和具有钙钛矿结构的SFMO也显示出良好的化学相容性。而且，具有多孔层的CSO-SFMO双相膜在苛刻的条件下表现出高的透氧性和良好的CO ₂耐受性。使用CSO-SFMO双相膜作为反应器，在膜的相对侧上获得合适的H ₂ / N ₂比为3和H ₂ / CO比为2。同时，CO的选择性为98％，CH ₄在900℃下，甲烷侧的转化率为97％，进料侧的合成气（H ₂  + N ₂）的生成率为3.0cm ³  min ^-1  cm ^-2。
