英文摘要: Mixed-conducting oxygen permeable membranes represent a class of novel ceramic membranes, which exhibit mixed oxygen ionic and electronic conductivities. At high temperatures, oxygen can permeate through the membrane from the high to low oxygen pressure side under an oxygen concentration gradient. Theoretically, the permselectivity of oxygen is 100%, Recently, a novel mixed-conducting membrane-Ba0.5Sr0.5Co0.8Fe0.2O3-delta has been developed, which shows extremely high oxygen permeability and promising stability. Furthermore, the reactor made with such membranes was successfully applied to the partial oxidation of methane to syngas reaction using air as the oxygen source, which realized the coupling of the separation of oxygen from air and the partial oxidation of membrane reaction in one process. At 850 degrees C, methane conversion > 88%, CO selectivity >97% and oxygen permeation rate of about 7.8 mL/(cm(2) . min) were obtained.
