【Abstract】 Asymmetric hollow fiber ceramic,La_0.6Sr_0.4Co_0.2Fe_0.8O_3-α（LSCF） membranes have been prepared through the phase inversion technique.Using the dense LSCF hollow fibre membranes,a hollow fibre membrane reactor was designed and fabricated with which pure oxygen could be separated directly from air.Oxygen yield may reach up to 48.27 L（STP）/m²（at 980℃） when the downstream pressure on the vacuum side is 5.33kPa.Such a LSCF hollow fibre membrane reactor may also be applied for various oxidation and dehydrogenation reactions.更多还原
