Methane oxidation to synthesis gas using lattice oxygen in La_(1-x)Sr_xFeO_3 perovskite oxides instead of molecular oxygen

摘要

In this paper,partial oxidation of methane to synthesis gas using lattice oxygen instead of molecular oxygen was investigated.A perovskite La_(1-x)Sr_xFeO_3(x=0,0.1,0.2,0.5)oxide was used as an oxygen provider.The redox cycle experiments show that methane can be oxidized to CO and H_2 by the lattice oxygen of La_(1-x)Sr_xFeO_3(x=0,0.1,0.2,0.5)oxide,while the lost lattice oxygen can be supplemented by re-oxidation.
