چکیده انگلیسی
In recent years, the purification of landfill gas (LFG) to produce pipeline-quality gas has attracted increased research interest also due to its crucial role of producing energy or other products. At present, the vast majority of catalytic deoxygen catalyst materials for the reduction of O2 in the LFG are Pd-, Pt, and Rh-based noble metals of various compositions. In this short communication, we proposed the perovskite-type oxides with general formula La1âxSrxCo0.2Fe0.8O3âd (Sr = 0.2, 0.4, 0.6, and 0.7) as catalysts for the deoxygen of LFG at intermediate temperature with the aim to reduce the use of precious and noble metals. Continuous performance tests demonstrate an O2 conversion of 100% at about 500 °C. In addition, the catalyst exhibits stability of the O2 conversion efficiency without any performance impact at 525 °C over a time period of about 4 days. The high-performance and durability test results obtained in this short communication are promising and represent an important step towards the successful implementation of new LFG deoxygen treatment technologies.
