英文摘要 | we prepared perovskite-type oxides la1-xsrxfeo3 (x = 0, 0.3, 0.5, 0.9) by a combustion method and used these as oxygen carriers for the partial oxidation of methane. x-ray diffration, scanning electron microscopy and h-2 temperature-programmed reduction techniques were used to characterize the samples. their reduction and oxidation activities were investigated using a thermogravimetric analysis reactor and fixed-bed reaction equipment, respectively. the results showed that the lattice oxygen in la1-xsrxfeo3 was suitable for the partial oxidation of methane to produce syngas. their capacity to provide oxygen was enhanced by the partial substitution of la3+ by sr2+ and the synthesized materials have good regenerability. the optimal degree of sr substitution was found to be x = 0.3-0.5 for la1-xsrxfeo3 with regard to reactivity, selectivity, and oxygen-donating ability. ch4 conversion was higher than 70%, and the n(h-2)/n(co) ratio remained about 2:1 and no obvious decomposition of ch4 occurred.
