Partial oxidation%methane%synthesis gas%lattice oxygen%La1-xSrxFeO3-λ perovskite oxides
In this paper, the partial oxidation of methane to synthesis gas using lattice oxygen of La1-xSrxMO3-λ (M=Fe,Mn) perovskite oxides instead of molecular oxygen was investigated. The radox circulation between 11% O2/Ar flow and 11% CH4/He flow at 900℃ shows that methane can be oxidized to CO and H2 with a selectivity of over 90.7% using the lattice oxygen of La1-xSrxFeO3-λ (x≤0.2) perovskite oxides in an appropriate reaction condition, while the lost lattice oxygen can be supplemented by air re-oxidation. It is viable for the lattice oxygen of La1-xSrx FeO3-λ (x≤0.2) perovskite oxides instead of molecular oxygen to react with methane to synthesis gas in the redox mode.
