Abstract:

Zeolite is a widely used inorganic crystalline material,but its synthesis process usually takes a long time,which reduces its synthesis efficiency.Therefore,the development of rapid synthesis technology of zeolite is the key technology to improve the synthesis efficiency of zeolite,but also an important means to reduce the cost and increase the efficiency of zeolite for the actual industrial production.The progress of rapid synthesis of zeolite at home and abroad commonly used technology was introduced.The rapid synthesis technology was classified and elaborated from three aspects,including the addition of crystallization promoter,process intensification technology and other synthesis technology.The inner reason for each technology to accelerate the zeolite synthesis speed was explained and at the same time their advantages and disadvantages were analyzed.Finally,based on the characteristics of each technology combined with the current requirements for environmental protection in the actual production of zeolites,the future development direction of molecular sieve rapid synthesis technology was proposed.

Key words: zeolite, fast synthesis, synthesis efficiency, process intensification
