应用组成为Ba0.5Sr0.5Co0.8Fe0.2O3-(的钙钛矿型混合导体陶瓷膜制成膜反应器。该膜在进行氧分离的同时具有活化甲烷氧化偶联的催化功能。随着温度升高和膜的富氧端氧分压的增大，透氧量有所增加。在空气、氦气的氧分压梯度下，850(C，膜厚度为1.5 mm时，JO2可达到1.2 mL/(cm3(min)。同时在800(C~900(C温度范围内，该膜对于甲烷转化为乙烷和乙烯一般只具有0.5%~3.5%的低转化率，而选择性可达40%~70%。在反应尾气中发现了大量的未反应的分子氧，说明过量的氧与甲烷未经催化反应的气相反应导致了C2的选择性相对较低。OCM膜反应模式情况下的透氧量与空气、氦气梯度情况下的透氧量相比只有微小增加，这与POM膜反应模式情况下透氧量大量增加显著不同。
The application of the composition of the Ba0.5Sr0.5Co0.8Fe0.2O3- (perovskite-type mixed conductor ceramic membrane membrane reactor made of the membrane oxygen separation at the same time with the activation of methane oxidation coupling catalytic function with the temperature And the oxygen partial pressure increased with the increase of the oxygen partial oxygen partial pressure of the membrane.Under the oxygen partial pressure gradient of air and helium, when the membrane thickness is 1.5 mm, the JO2 can reach 1.2 mL / (cm3 (min).) In the meantime, the conversion of methane to ethane and ethylene at 800 (C ~ 900 (C temperature range) generally has only a low conversion of 0.5% ~ 3.5% and a selectivity of up to 40% ~ 70% .A large amount of unreacted molecular oxygen was found in the reaction tail gas, indicating that the gas phase reaction of excess oxygen with methane without catalytic reaction resulted in a relatively low selectivity of C2. In the case of the OCM membrane reaction mode, oxygen The amount of oxygen increased only slightly compared with the oxygen permeability in the case of air and helium gradients, which was significantly different from the large increase in oxygen permeability under the POM membrane reaction mode.
