摘　　要：透氧膜反应器稳定性除受膜材料本身性能和膜反应器所处气氛影响外,重整过程所用催化剂与膜材料的反应问题同样值得关注。以透氧膜反应器焦炉煤气甲烷部分氧化重整用BCFNO膜材料为研究对象,分别通过SEM和XRD分析Al2O3、MgO、YSZ、β分子筛、TiO2等催化载体材料与BCFNO透氧膜材料的长时间反应情况,目的是为BCFNO透氧膜反应器所用催化剂材料选择提供依据。实验结果表明β分子筛、Al2O3和TiO2容易与BCFNO透氧膜材料反应形成新的相。MgO也与BCFNO反应,但反应较小,YSZ不与BCFNO发生反应。The stability of oxygen permeable membrane reactor was affected by the property of membrane materials and atmosphere in the membrane reactor besides,the reaction of the reforming catalyst and membrane materials also should be considered.The BCFNO membrane materials used in partial oxidation of methane in coke oven gas in an oxygen permeation membrane reactor as a object of study in this paper,analyzing the long time reaction condition of the Al2O3,MgO,YSZ,β-molecular sieve,TiO2 etc catalyst carriers to BCFNO membrane materials,aiming to provide a way to choose the catalyst material for the BCFNO membrane reactor.The experimental results show that the β-molecular sieve,Al2O3 and TiO2 reacts with BCFNO membrane and forms a new phase,MgO also reacts with BCFNO membrane but react little,how ever YSZ does not react with BCFNO membrane.
