A porous perovskite BaCo(x)Fe(y)Zr(0.9-x-y)Pd(0.1)O(3-delta) (BCFZ-Pd) coating was deposited onto the outer surface of a BaCo(x)Fe(y)Zr(1-x-y)O(3-delta) (BCFZ) perovskite hollow-fiber membrane. The surface morphology of the modified BCFZ fiber was characterized by scanning electron microscopy (SEM), indicating the formation of a BCFZ-Pd porous layer on the outer surface of a dense BCFZ hollow-fiber membrane. The oxygen permeation flux of the BCFZ membrane with a BCFZ-Pd porous layer increased 3.5 times more than that of the blank BCFZ membrane when feeding reactive CH(4) onto the permeation side of the membrane. The blank BCFZ membrane and surface-modified BCFZ membrane were used as reactors to shift the equilibrium of thermal water dissociation for hydrogen production because they allow the selective removal of the produced oxygen from the water dissociation system. It was found that the hydrogen production rate increased from 0.7 to 2.1 mL H(2) min(-1) cm(-2) at 950 degrees C after depositing a BCFZ-Pd porous layer onto the BCFZ membrane.

“…Mixed conducting oxides have been attracting much attention in view of their promising applications, such as cathode and anode materials for solid oxide fuel cells [1], membranes for pure oxygen production and conversion of hydrocarbons to value-added products [2][3][4][5][6][7][8][9]. Over the past two decades, a number of mixed conducting materials based on perovskite-type oxides have been developed to meet many kinds of requirements in practical applications.…”

“…Thursfield and Metcalfe 34 also used a silicone tube for sealing the linear hollow-fiber membranes. Wang et al 35 sealed an Au-coated hollow fiber with a silicon rubber ring for the high-purity oxygen production by perovskite hollow-fiber membranes swept with steam. Silicone sealant was also used by Tan et al 36 for the oxygen production through La 0.6 Sr 0.4 Co 0.2 Fe 0.8 O 3Àd perovskite hollow-fiber membranes.…”

The oxygen permeation of dense U-shaped perovskite hollow-fiber membranes based on Ba 0.5 Sr 0.5 Co 0.8 Fe 0.2 O 3Àd prepared by a phase inversion spinning process is reported. The perovskite hollow fibers with totally dense wall were obtained with the outer diameter of 1.147 mm and the inner diameter of 0.691 mm. The dependences of the oxygen permeation on the air flow rate on the shell side, the helium flow rate on the core side, the oxygen partial pressures, and the operating temperatures were experimentally investigated. According to the Wagner theory, it follows that the oxygen transport through the U-shaped hollow-fiber membrane is controlled by both surface reaction and bulk diffusion at the temperature ranges of 750-950 C. High oxygen permeation flux of 3.0 ml/(min cm 2 ) was kept for about 250 h at 950 C under the conditions of the air feed flow rate of 150 ml/min and the helium flow rate of 50 ml/min.
