摘要：

The BaCo(0.7)Fe(0.2)Nb(0.1)O(3-delta)(BCFNO) membranes combined with Ce(0.8)Re(0.2)O(2-delta)(Re=La, Y) layer on the permeation side were used for hydrogen production by partial oxidation reforming of coke oven gas (COG). The Ce(0.8)Re(0.2)O(2-delta) improved the oxygen permeation flux of the membrane by 11-28% at 750 degrees C. The high oxygen permeation flux achieved using the Ce(0.8)Re(0.2)O(2-delta) surface-coating layer in this work are quite encouraging with a maximum value reaching 19.7 ml/cm(2).min at 900 degrees C, which will be promising surface modification materials in the catalytic partial oxidation reforming of COG.
