Comparison of LaFeO_3,La_(0.8)Sr_(0.2)FeO_3,and La_(0.8)Sr_(0.2)Fe_(0.9)Co_(0.1)O_3 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 La_(0.8)Sr_(0.2)Fe_(0.9)Co_(0.1)O_3 oxide,while LaFeO_3 and La_(0.8)Sr_(0.2)FeO_3 exhibited excellent structural stability and continuous oxygen supply.
Comparison of LaFeO_3, La_ (0.8) Sr_ (0.2) FeO_3, and La_ (0.8) Sr_ (0.2) Fe_ (0.9) Co_ (0.1) O_3 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 La 0.8 Sr 0.2 0.2 0.9 Co 0.1 O 3 oxide, while LaFeO 3 and La 0.8 0.8 Sr 0.2 FeO 3 show excellent structural stability and continuous oxygen supply.
