The perovskite-type oxygen-transporting membranes of BaCo0.7Fe0.2M0.1O3 - delta (M = Ta, Nb, Zr) were prepared by solid state reaction methods and used for producing hydrogen from coke oven gas (COG). The structural stability of the membranes was characterized systematically using XRD, H-2-TPR, O-2-TPD, TG-DSC, and SEM-EDXS. Meanwhile, the oxygen permeation flux of the membranes was measured at different temperatures under He or CO2 containing atmosphere. It can be concluded that the Ta-substituting BaCo0.7Fe0.2M0.1O3 - delta is a promising candidate of the membrane materials for producing hydrogen through the catalytic partial oxidation of COG.
