    He Yufei, born in 1988, doctoral degree, School of Chemistry intern professor, doctoral supervisor. Mainly engaged in research in the field of industrial catalysis, focusing on the core problem of controllable construction of alumina-based supported catalysts with reaction-mass transfer coordination, a new idea of construction of supported catalysts with multi-functional and mesoporous alumina carriers and synergic enhancement of endogenous reaction kinetics and mass transfer was proposed, which was used as the backbone of a new generation of anthraquinone hydrogenation catalysts for 200,000 tons of hydrogen peroxide industrial plants. As the project leader, he undertook 1 young scientist project of the national 14th Five-Year Plan key research and development plan, presided over 2 projects of the National Nature Fund, presided over and participated in more than 10 horizontal projects of enterprises, and was selected as the Double and creative talents project plan of Jiangsu Province. He has published more than 40 papers in mainstream journals in the field of chemistry and chemical engineering, and authorized 20 invention patents. At present, he is a member of the Chinese Chemical Society, a member of the Chemical Society of China, a youth member of the Industrial Catalysis Alliance, and a youth member of the Fine Chemical Professional Committee.

    Focusing on the core problem of controllable construction of reaction-mass transfer synergic alumina-based supported catalyst, taking hydrogen peroxide by anthraquinone process as the target reaction, the novel idea of alumina multi-function and pore structure regularization was proposed. The basic problems of reaction and mass transfer and engineering bottleneck were solved through the innovation of alumina carrier and preparation technology: (1) Controlled construction of alumina with active hydrogen transfer function, proposed the use of multi-functional carrier to decouple the competitive adsorption on metal site, improving the reaction rate; (2) Controllable preparation of high strength and large aperture spherical alumina with interconnecting pores, proposed a new cross-linked polymerization-oriented interconnecting mesoporous pore control approach, breaking through the intrapore diffusion limit; (3) Controllable preparation reaction-mass transfer synergistic industrial catalysts, developed a new coordination load method to achieve the coordination of alumina and metal. I break through the engineering preparation technology by equivalent scale-up research, and complete the kilogram scale model test. The optimized catalysts were applied to 200,000 t/a industrial equipment, to solve the problem of efficiency and consumption. It is proposed to construct a new fixed-fluidized bed to develop a new process strengthening technology, which is intended to maximize the catalyst potential by solving the matching problem of three-phase transfer and reaction rate under confined fluidization.
