N2 - A mixed-conducting multichannel hollow fiber membrane (MCMHF) based on CO2-tolerant SrFe0.8Nb0.2O3-δ (SFN) oxide has been successfully prepared by phase inversion and sintering technique. The morphology, breaking load, oxygen permeability under CO2 atmosphere, thermal cycling performance and the long-term stability of the membrane were investigated in detail. The prepared membrane has a significantly high oxygen permeation flux, which is the highest value among the membranes using pure CO2 as sweep gas. The as-prepared MCMHF membrane has good thermal-mechanical stability in the repeated heating and cooling process. Furthermore, by using pure CO2 as sweep gas, the MCMHF membrane is operated stably for more than 500h without any degradation of oxygen permeation flux. Our work demonstrates that the MCMHF membrane has a great potential for the practical application in the oxyfuel process for CO2 capture technology.
