摘要：
<正>Comparison of LaFeO3,La0.8Sr0.2FeO3,and La0.8Sr0.2Fe0.9Co0.1O3 perovskite oxides as oxygen carrier for partial oxidation of methane in the absence of gaseous oxygen was investigated by continuous flow reaction and sequential redox reaction.Methane was oxidized to syngas with high selectivity by oxygen species of perovskite oxides in the absence of gaseous oxygen.The sequential redox reaction revealed that the structural stability and continuous oxygen supply in redox re- action decreased over La0.8Sr0.2Fe0.9Co0.1O3 oxide,while LaFeO3 and La0.8Sr0.2FeO3 exhibited excellent structural stability and continuous oxygen supply.
