“…Recently, increasing activities can be observed in the preparation of oxygen ion conducting membranes in hollow-fiber geometry. Examples are the pioneering papers from the groups of Li, [19][20][21][22][23][24] Liu, [25][26][27] and Schiestel, [28][29][30] as well as the papers by Trunec 31 and Luyten et al 32 showing that the Correspondence concerning this article should be addressed to H. Wang at hhwang@scut.edu.cn. thin-walled ceramic hollow-fiber membrane can be prepared by wet spinning.…”

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.

“…[13][14][15] Compared to the disk-shaped membranes, such hollow-fiber membranes possess much larger membrane area per unit volume for oxygen permeation. By adopting long hollow fibers and keeping the two sealing ends away from the high-temperature zone, the problem of high-temperature sealing no longer exists.…”

“…Although ceramic hollow-fiber membranes are still in their early stage of development, very important progress has recently been reported. [13][14][15][16][17][18][19] The well-established immersion-induced phase-inversion technique, commonly used to prepare polymeric hollow-fiber membranes, can be modified to prepare inorganic hollow-fiber precursors. Subsequently, the fiber precursors are heated to remove the polymer and sintered to a porous or dense structure.…”
