AIChE J. continuously reports the latest achievements of East China University of science and technology in the study of pore structure design of industrial granular catalyst

Recently, AIChE Journal reported the latest research work of the catalytic reaction engineering research team in the State Key Laboratory of chemical engineering, East China University of science and technology in the structural design of industrial granular catalyst pore network in the presence of deactivation by collaborating (DOI: 10.1002 / AIC 16687) This is the fourth paper that the team published on AIChE journal around the pore structure design of industrial granular catalyst The first three papers are AIChE J 2019, 65, 140-150; AIChE J 201 7, 63, 78-86; AIChE J 2016, 62, 451-460 Catalyst is the pillar of modern chemical industry and the core technology of chemical production The development of industrial granular catalysts includes the design of micro scale active sites and meso scale carrier particles At present, most researches focus on the micro scale active sites, but few researchers pay attention to mesoscopic scale carriers The catalyst particles have very complex multi-stage pore structure and rich surface interface structure, and complex diffusion reaction coupling process occurs in these complex structures In order to rationally design the pore structure and surface interface structure of catalyst particles, a reasonable mathematical model is needed The team developed an advanced pore network model for the pore structure design of industrial granular catalyst, and applied the mathematical model to the study of important industrial reaction systems such as benzene hydrogenation, Claus reaction and propane dehydrogenation The complex processes of diffusion, reaction, phase transformation, coking, pore plugging and deactivation in these industrial catalyst particles were analyzed; the "structure-activity" relationship between the pore network structure and catalyst performance was quantified; the optimization design scheme of the multi-level pore network structure of catalyst particles was proposed, which can greatly improve the activity, selectivity and stability of catalyst particles Chemical reaction engineering is the characteristic and advantage research direction of the State Key Laboratory of chemical engineering of East China University of science and technology It is mainly aimed at the design and development of reactor This series of research work provides an important theoretical basis for the design of carrier form and pore structure of industrial catalyst, and is an important expansion of chemical reaction engineering At present, the research group is working with many enterprises to optimize the catalyst geometry and pore structure parameters to improve the operation performance of industrial catalyst and reactor The first author of this series of research work is Ye Guanghua, a specially appointed associate researcher of the school of chemical engineering, East China University of science and technology, and the corresponding author is Professor Zhou Xinggui The co corresponding authors include Professor Marc Olivier coppers of University College London and Professor freich J keil of Hamburg University of technology Relevant research work has been supported by NSFC and the first-class discipline construction fund of East China University of science and technology.
