Abstract: A new series of Ba-Co-Operovskite-type oxygen carriers has been successfully synthesized by the microwave-assisted sol-gel method and further applied for producing an O2/CO2 mixture gas. The oxygen adsorption/desorption performance of synthesized samples was studied in a ?xed-bed reactor system. Effects of A/B-site substitution on the oxygen desorption performance of Ba-Co-O–based perovskites are also included. Furthermore, the effects of operating conditions including the adsorption time and temperature as well as the desorption temperature on oxygen production performance were investigated in detail. The results indicated that BaCoO3-? exhibited an excellent oxygen desorption performance among the synthesized A/B-site–substituted ACoO3-? and BaBO3-? samples, and that the optimal adsorption time, adsorption temperature and desorption temperatureforBaCoO3-? were determined to be 20min, 850?Cand850?C, respectively, in this study.
