Effect of Phase Ratio on Hydrogen Separation of Dual‐phase Membrane Reactors
Three dual‐phase MIEC membranes (100 – x) wt % Ce0.8Sm0.2O1.9 (SDC) – x wt % Sr0.92Ti0.5Fe0.5O3–δ (STF) (x = 30, 40, 50) were prepared by a one‐pot solid state reaction to explore the effect of phase ratio of dual‐phase membranes on the hydrogen separation performance of oxygen‐permeable membrane reactors. Single‐phase STF was synthesized by the same method for comparison. The grains of the two phases in the three dual‐phase membranes are uniformly and continuously distributed forming the three‐dimensional connected networks. Dual‐phase membranes have higher total conductivity than that of STF under simulated working atmospheres, and the total conductivity decreases with the increase of STF content. Under various test conditions, the hydrogen separation rate of the dual‐phase membranes is higher than that of the STF membrane.
