摘 要：Perovskite-type oxygen-permeable membrane reactors of BaCo0.7Fe0.2Nb0.1O3-δ （BCFNO） packed with Ru-based catalyst had high oxygen permeability and could be used for hydrogen production by partial oxidation of methane in coke oven gas （COG）.At 1173 K,94% of methane conversion,85% of H2 selectivity,107% of CO selectivity,and as high as 15.4 mL·cm-2·min-1 of oxygen permeation flux were obtained.The BCFNO membrane itself had poor catalytic activity to partial oxidation of CH4 in COG.During continuous operation for 70 h at 1173 K,no degradation of the membrane reaction performance was observed.XRD and SEM characterization also demonstrated that the BCFNO membrane reactor exhibited good stability in partial oxidation of methane in COG.
