Novel SrCo0.9W0.1O3‐δ Hollow Fiber Ceramic Membrane with Enhanced Oxygen Delivery Performance and CO2 Resistance Ability

The development of the CO2-resistant mixed ionic-electronic conducting membranes can significantly expand their application into many CO2 involved processes, such as the oxy-combustion process and green chemical synthesis in membrane reactors. In this work, the SrCo0.9W0.1O3-d (SCW) hollow fiber mem...

description The development of the CO2-resistant mixed ionic-electronic conducting membranes can significantly expand their application into many CO2 involved processes, such as the oxy-combustion process and green chemical synthesis in membrane reactors. In this work, the SrCo0.9W0.1O3-d (SCW) hollow fiber membranes were fabricated via a combined phase inversion and sintering method. The oxygen permeation flux of 4.18 mL min-1 cm-2 was achieved at 950 °C when pure He was used as sweep gas, while this flux can be further improved by 20.81% after Ag modification of outside membrane surface. Furthermore, the oxygen permeation behavior under CO2 in the sweep gas and surface morphology has been investigated. The oxygen permeation flux experienced a slight decline, then reached a plateau at 2.44 mL min-1 cm-2 during permeation evaluation of 70–100 hours at 900 °C when swept by 10% CO2-containing gas mixture of 100 mL min-1. More interestingly, the oxygen permeation flux only exhibited 9.44% decrease of the original flux value after switching the sweeping gas back to He, which can be attributed to the formation of the porous layer on the inside surface of membrane. The porous layer would reduce the membrane thickness, meanwhile supply more inside membrane surface area, facilitating the oxygen permeation.
