Scientific research in Li Chenglie

As early as 1950s, Mr. Li Chenglie's teaching and research group began to study the adsorption dewaxing of 5A molecular sieve, and achieved good results, which attracted extensive attention. In teaching and scientific research, Mr. Li is very concerned about the research on the development of scientific research at home and abroad. In order to understand the needs of production, young Li Chenglie often went to the factory to participate in some production practices, and also consulted a large number of documents through retrieval tools such as CA and CPI to understand the new trends of professional development. In the investigation, he paid special attention to the special position of catalytic processing in changing refining process and improving product quality. According to the characteristics that most catalytic reactions in petroleum processing depend on the acidic center of the catalyst, Li Chenglie chose molecular sieve catalysis as his lifelong research direction, and started the research work of "isomerization of low-carbon alkanes", and established a pressure micro-reverse catalytic device earlier, which created conditions for the rapid and in-depth research and development of the catalyst. In order to speed up the industrialization of isomerization process, the research team led by Li Chenglie cooperated with China Petrochemical-Jinling Petrochemical to carry out the research on the catalytic isomerization process of low-carbon alkanes on Pd- mordenite, and won the second prize of scientific research progress of China Petrochemical. At that time, the results of isomerization reaction and isomerization reaction kinetics attracted the interest of Professor Kristoffel in Germany. Professor Kristoffel and Mr. Li's research group conducted cooperative research on reforming catalysis in 1983- 1984. Li Chenglie's research group applied for two patents in the field of isomerization. He also edited two monographs, Catalyst Deactivation and Hydrocarbon Isomerization, and co-edited some chapters of Catalytic Naphtha Reforming (edited by G.J. Antos and A.M. Aitan) and Zeolite Catalytic and Separation Technology.
