Title : Fabrication and characterization of perovskite catalyst for oxygen removal in landfill gas (LFG)


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 in 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 work, the perovskite-type oxides with general formula La1-xSrxCo0.2Fe0.8O3-d (x=0.1-0.9) are proposed as advanced methane oxidation catalysts for the deoxygen technology of LFG at intermediate temperature with the aim to reduce the use of precious and noble metals. The hollow fiber type catalyst with o.d. 1.4 mm/ i.d. 0.7 mm/10 mm length was prepared and tested in a lab-scale oxygen removal equipment under various temperature and feed conditions. The total oxygen conversion was confirmed at 475? and it was maintained over 100 hours in a long-term test.


Dr. Park studied his bachelor (1988/1993), master’s degree (1996/1994) and Ph.D. (1996/2000) at the Department of Chemical Engineering of the Korea University, Seoul (Korea). From 2000 to 2013 he was a researcher at the Korea Institute of Energy Research (KIER), Daejeon (Korea). Actually, Dr. Jung Hoon Park is an Assistant Professor at the College of Engineering of Dongguk University in Seoul (Korea) and team leader of a laboratory specialized on Carbon capture and storage (CCS). His activity focuses on oxygen separation using ion transport membrane as well as hydrogen separation using metal and ceramic composite membrane, fine ceramic synthesis using hydrothermal reaction, and supercritical water extraction.
