中文摘要：

采用相转移纺织技术制备了致密的纯相钙钛矿BaCo（0.4）Fe（0.4）Zr（0.2）O（3-δ）（BCFZ）中空纤维透氧膜.并用所制备的BCFZ中空纤维膜构建反应器对甲烷部分氧化制合成气进行研究.结果表明：在没有催化剂时,BCFZ膜材料本身对甲烷的活性较低,甲烷转化率低于3%;而加入Ni基催化剂后,甲烷的转化率提高到93%以上、CO选择性为80%左右,透氧量为11mL/min·cm^2左右.中空纤维膜反应器中初始阶段的活化只需要90min,比片状膜反应器要快得多.同时对在反应情况下,BCFZ中空纤维膜膜反应器的稳定性进行了初步的研究。结果表明,BCFZ中空纤维膜在40h的操作中具有较好的稳定性.

英文摘要：

The dense perovskite hollow fiber made of BaCo（0.4）Fe（0.4）Zr（0.2）O（3δ）（BCFZ）was prepared by phase inversion spinning followed by sintering.The crystal structure and the microstructures of the hollow fiber membrane were characterized by X-ray diffraction（XRD）and scanning electron microscope （SEM）.The sintered hollow fiber membrane was also used to construct a reactor for the partial oxidation of methane（POM）to syngas.It is found that the BCFZ itself exhibits low activity for conversion of methane which is lower than 3% without catalysts.After Ni-based catalyst is introduced,the conversion of methane,the CO selectivity and the oxygen permeation flux reach 93%,80% and 11mL/min·cm2, respectively.It takes only 90min to get the steady state at initial stage in the hollow fiber membrane reactor,which is much shorter than that in Lhe disk-type membrane reactor.The hollow fiber membrane reactor is steadily operated for 40h for the POM reaction.
