报告人简介

Professor Yongdan Li, is now the tenured full Professor of Industrial Chemistry in Aalto University, Finland and also the Changjiang Chair Professor of Industrial Chemistry of Tianjin University, China. He was the Founder and Director of the Tianjin Key Laboratory of Applied Catalysis Science and Engineering at the School of Chemical Engineering and Technology, Tianjin University, China. After finishing his Ph.D. in Industrial Catalysis at Tianjin University in 1989, he went to the University of Twente in the Netherlands and worked there as a post-doc for a year. He did a second post-doc at Ecole National Superior of Industrial Chemistry, Nancy, France. Dr. Li returned to Tianjin University at the end of 1992 where he was promoted to a Full Professor at the beginning of 1994. He has served as the Chairman of the Department of Catalysis Science and Technology and the Coordinator of the Industrial Catalysis Program since 1997 to 2017. This program was twice ranked as the 1^st in China, in 2001 and 2006. Dr. Li received the most prestigious award given to Chinese Young Scientists, “The NSF Award to Outstanding Young Scientist” in 2004, and obtained the most important title for professors in China “The Changjiang Chair Professorship” in 2007. He serves now also as the Associate Editor of Catalysis Today and the Associate Editor of the CIESC Journal.

Seminar: Lignin conversion in supercritical ethanol

Professor Yongdan Li

Chair Professor of Industrial Chemistry, Department of Chemical and Metallurgical Engineering,

School of Chemical Technology, Aalto University, Finland

And Changjiang Chair Professor of Industrial Catalysis, Tianjin University, China

Abstract：Lignin is one of the major components of lignocellulose biomass, which is self-produced in a large volume by the biosphere on the Earth, and is the best renewable resources for the production of aromatic compounds. This seminar introduces the recent progresses on the catalytic decomposition of lignin in supercritical alcohols, especially ethanol. A number of catalysts based on molybdenum will be discussed. Further analysis of the mechanism reveals that supercritical ethanol without a catalyst can depolymerize lignin into fragments with a molecular weight of around 1000 and the catalyst further converts the intermediate sized molecules into small molecules suitable for fuels and chemicals.
