Abstract

The dense perovskite hollow fiber made of BaCo0.4Fe0.4Zr0.2O3-δ (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 the disk-type membrane reactor. The hollow fiber membrane reactor is steadily operated for 40h for the POM reaction.

Key words： hollow fiber; POM; perovskite; catalysis in membrane; mixed conductor
