Abstract:
Dense Bi1.5Y0.3Sm0.2O3-La0.8Sr0.2MnO3–δ hollow fiber membrane was fabricated by the combined phase inversion/sintering technique. The hollow fiber possessed an asymmetric structure. The oxygen permeability of the hollow fiber was measured by exposing its shell side to ambient air and sweeping the core side with helium to carry away the permeated oxygen. An oxygen permeation flux 3.9×10–7 mol cm–2 s–1 was obtained at 850℃ under a gradient of air/helium. The oxygen permeation flux was related to the helium sweeping rate, the length of the hollow fiber and the oxygen partial pressure on the feed side, and can be further increased by modifying the membrane surfaces.
