Abstract

Recently, some perovskite-type oxides with general formula La_1−xSr_xCo_0.2Fe_0.8O_3−d (0.2 < Sr_x < 0.7) were found to have reasonable catalytic activity and stability for the deoxygen reaction of landfill gas (LFG) at intermediate temperature. This study selects La_0.1Sr_0.9Co_0.2Fe_0.8O_3−d (LSCF) at high Sr_x content (Sr_x = 0.9) as a case study to investigate the effects of O₂ content on methane oxidation reaction to remove oxygen from the LFG with two compositions characterized by low (1%) and high (2%) O₂ content. The complete oxygen conversion performance (100%) during methane oxidation was found at 425–450 °C and it was maintained throughout the duration of a long-term experiment (100 h).
