A study on the feasibility of the catalytic methane oxidation for landfill gas deoxygen treatment

•Oxygen in landfill gas can be removed by catalytic oxidation process.•Bimetallic Pt–Rh/γ-Al2O3 catalyst is suitable for the deoxygen of LFG.•The temperature for the deoxygen reaction is lower than 460°C.•The deoxygen reaction is fastly started-up, and can self-operate without extra heat.•The catalyst employed can work under wide range of operating conditions.
