Hongzhong LI, Member of Chinese Academy of Sciences, Fellow of Royal Society of Chemistry, chemical engineering expert, and now serves as research professor, tutor of Ph. D. students, Director of Academic Committee, Institute of Process Engineering (IPE), Chinese Academy of Sciences (CAS). He was Director of Engineering and Technology Committee, IPE, CAS (2006-2008 )，Director of the Academic Committee, IPE, CAS (2000-2004)，Deputy Director of the Academic Degree Committee, Institute of Chemical Metallurgy (ICM), CAS (1995-1999)，Deputy Director of ICM, CAS（1995-1999）, and Deputy Director of the Academic Council, State Key Laboratory of Multi-Phase Complex System at IPE, CAS in Beijing (2006-2014).
He was born in Xiyang County, Shanxi Province in 1941 and graduated from the Department of Chemical Engineering, Taiyuan University of Technology in 1965. He worked as a Assistant Fellow and Assistant Professor at Institute of Coal Chemistry (ICC), CAS, Taiyuan, Shanxi Province, China (1965-1978). He obtained his MS degree from the University of Science and Technology of China in 1981 and his Ph. D. degree from the ICM, CAS in 1986. He worked as a Postdoctoral Fellow at the Department of Chemical Engineering, University of British Columbia (UBC), Canada (1986-1988).
Prof. Li's research specialty is gas-solids fluidization. When he worked at ICC, CAS, he engaged in developing a Fluidized Bed Reactor to Convert Butene into Butadiene, which belonged to the state key project for butadiene rubber and this project was awarded the State Top Class Prize for Science and Technology Progress in 1985.
When he worked at UBC, Canada, he engaged in the combustion of different fuels in a pilot scale circulating fluidized bed combustor, and the paper titled "Combustion characteristics of different fuels in a pilot scale circulating fluidized bed combustor" was awarded the Best Paper Prize at the 10th International Conference on Fluidized Bed Combustion in 1989 in San Francisco.
When he worked at IPE ( named ICM before 2001), he undertook the great projects of the 7th five-year plan and the 8th five-year-plan of Nature Science Foundation of China, the major project of 9th five-year-plan of Nature Science Foundation of China, and several projects from enterprises. He studied the moving- bed gas-solids two phase flow，and the particulatization of gas-solids fluidization.
By coupling the basic principles of multi-phase flow with the particulate media mechanics, he established the dynamic theory of gas-solids moving beds and the models to describe the gas and solids flows in vertical and inclined moving beds . It is capable of predicting the gas and solids flow rates, the distributions of the gas pressures, the contacting stresses between particle and wall and between particles, and the arching width. He developed the dynamic models and design methods for the V-valve, L-valve, and U-valve, which are used to pneumatically control the solids flow rate in circulating fluidized beds, and invented moving-bed type V-valve and pneumatically controlled peristaltic feeder, vertical pneumatic critical moving bed transport etc..
By using a ICM self-developed optic fiber micrograph probe, he succeeded in taking photos of transient clusters and the two-phase structures of dilute and dense phases in fast fluidized bed. His creative work leads to the proof of the agglomerating phenomena and the great attention of scientists from both domestic and overseas.
He established and proposed the new concepts of natural agglomerate number and fluidization agglomerate number, used in evaluating the agglomerating ability and fluidization quality for the nano and micro particles. He also established the force-balance model for agglomerate collisions, which can more accurately predict the balancing size of agglomerates in fluidized beds.
He proposed the theory and method of particulatization of gas-solids fluidization including particle and additive design (the particle design involves density, size and size distribution, shape and surface status etc. the additive selection means to select suitable fine particles or coarse particles as the additives.), fluid design (fluid density and viscosity), external field design (vibrating field, acoustic field, centrifugal force field, and magnetic field etc.), and internals-vessel configuration design (ring internals, perforated plate, remiform internals, shutter typed internals, shallow bed, conical bed, fast fluidized bed, turbulent bed etc.), which can restrain and eliminate the bubbles and agglomerates in gas-solids fluidized beds, and realize the particulate and homogeneous fluidization.
At present he undertakes the project of the National Basic Research Program of China, the major project of 11th five-year-plan of Nature Science Foundation of China, and several projects from enterprises. He is interested in studying the prediction and optimal control of the local structure in gas-solids fluidized beds, the relationship between local structure and transfer and reaction rates, and the computer simulation of fluidized bed reactors and their scale-up, which are the frontier research problems of this field.
He has published more then 200 papers, 6 chapters and 4 books. He was authorized 12 China Practical Patents and 22 China Invention Patents. He won the First Class Nature Science Prize awarded by Chinese Academy of Sciences in 1999, the Second Class Nature Science Prize awarded by Chinese Academy of Sciences in 1997, three First Class Prizes of Science and Technology Progress awarded by the Chinese Society of Petroleum and Chemical Industries in 2009 and 2012, and the Book Prize of China Press Government Prizes awarded by News and Press Office of China in 2010 for the “Handbook of Fluidization” edited by Mooson Kwauk and Hongzhong Li. He is the Vice President of Chinese Society of Particuology; Member of the standing council of the Chemical Industry and Engineering Society of China; Member of the editorial boards or the advisory editorial boards of China Powder Science and Technology, Chinese Journal of Process Engineering, Computers and Applied Chemistry, Journal of Engineering Studies, and Chemical Engineering (China).
