英文摘要	An asymmetric 75 wt% sm0.15ce0.85o1.925-25 wt% sm0.6sr0.4al0.3fe0.7o3-delta (sdc-ssaf) dual-phase mixed ionic-electronic conducting (miec) oxygen-permeable membrane reactor was applied to coproduce ammonia synthesis gas (asg, h-2/n-2 = 3) and liquid fuels synthesis gas (lfsg, h-2/co = 2). the effects of ch4 concentration, ch4 flow rate, steam flow rate and temperature on the performance of the membrane reactor were studied. the sdc-ssaf membrane reactor showed an excellent performance for the coproduction of asg and lfsg. an asg production rate of 20.7 ml cm(-2) min(-1), a lfsg production rate of 51.0 ml cm(-2) min(-1) and an oxygen permeation rate of 9.1 ml cm(-2) min(-1) were achieved at 925 degrees c. compared with traditional industrial processes, the energy saving of this membrane reactor process is expected as high as 66.5%. the post-mortem of the membrane reactor using scanning electron microscope (sem) and energy dispersive spectroscopy (eds) characterization revealed that the membrane has an excellent structural stability under operation condition.
