报告人简介：Professor In-Sik Nam received his PhD in Chemical Engineering from the University of Massachusetts, Amherst in 1983. He began his career at POSTECH in Korea in 1987, after a brief research and teaching career at the University of Gent in Belgium and Wayne State University in Detroit. Currently, he is an emeritus professor in chemical engineering and a research professor in environmental science & engineering at POSTECH. His research interest is mainly environmental catalysis and reactor design in the area of emission control technology including urea-SCR, HC/OHC-SCR and reaction kinetics of TWC. He has been appointed as one of five editors for “Applied Catalysis B: Environmental”, since 2007. He was president of Korea Institute of Chemical Engineers (KIChE) in 2010. More recently, he received the prestigious National Medal from the President of Korea (UngBi Jang) in April, 2013 and the 11th Presidential Engineering Award in December, 2015 for his outstanding contribution for the progress of Catalysis & Chemical Engineering Science and Education.

报告摘要：In this presentation, the progress and challenges in the urea/SCR technology to remove NO_x from diesel engine will be reviewed in the topics ranging from the underlying catalysis to the recent research trend and commercial applications. Included in the discussion will be the promoted SCR catalyst by the modification of catalyst support as well as the bimetallic catalyst systems aimed at improving the low temperature activity of the current urea/SCR catalysts and their catalytic characteristics. In addition, the local environment of active sites in CuSSZ13 and CuLTA, currently regarded as the promising commercial SCR catalyst, will be discussed by ESR and XANES studies in order to understand its strong thermal stability. Also presented will be the tolerance of zeolite-based SCR catalyst toward CO₂, recently reported as a new deactivating precursor for the urea/SCR catalyst.
