Abstract:

Zeolite molecular sieves are indispensable catalysts in many industrial processes. Among them, Beta zeolite has become one of the most widely produced zeolite materials with industrial significance because of its three-dimensional macroporous structure. Compared with the traditional Beta zeolite, the hierarchical Beta zeolite has many advantages such as smaller steric hindrance, higher mass transfer efficiency and so on, which can reduce the formation of carbon deposition, prolong the service time of catalyst and improve the utilization efficiency of catalyst. This review introduces the synthesis of hierarchical Beta zeolite in detail from the two strategies of “bottom-up” (direct synthesis) and “top-down” (post modification). The synthesis of hierarchical Beta zeolite by hard template method, soft template method, mesoporous template method, dealuminization method and desilication method are introduced, and the characteristics of hierarchical Beta zeolite are briefly introduced. The advantages and problems of various synthesis methods are summarized and the future development prospects are also prospected.

Key words: Hierarchical pore, Beta zeolite, Catalyst
