Abstract:

Catalysts with zeolite as active component have the advantages of easy recovery, non-corrosion, and environmental friendliness, and thus have been widely used in petrochemical industry. Designing and developing high-performance zeolite catalyst to achieve efficient chemical reaction can provide technical support for energy conservation and consumption reduction in chemical enterprises. The recent technological progress in the development of efficient zeolite was reviewed from four aspects, including active center construction and modification scheme of aluminosilicate and titanosilicalite zeolite, the construction scheme of mesopore structure inside and outside microporous zeolite, the preparation scheme of nanoscale zeolite particles and oriented growth control of zeolite nanocrystal, and topological structure innovation scheme of new structure zeolite. The future development direction of zeolite catalyst was also discussed. And it was pointed out that China still needs to strengthen technological innovation in this field, especially the original innovation, to achieve the deep integration of industry, academia, and research, to transform the advanced technology into practical solutions and the ultimate industrial applications.

Key words: zeolite, catalysts, multiphase reaction, active center, pore structure, crystal morphology, new topological structure
