沸石分子筛的粒径大小是影响其性能的一个重要参数。小晶粒ZSM-5分子筛因其具有更大的外表面积，更多的活性中心，高表面能，在提高催化剂利用率，增加大分子转化能力，减小深度反应，提高选择性以及降低结焦失活等方面均表现出优越性能，得到人们的广泛关注。本文综述了小晶粒ZSM一5分子筛的合成方法，改性手段与催化应用优势。

The grain size was one of the most important characteristic parameters of molecular sieves. Small crystal - size ZSM -5, because of its larger external surface area, much more active centers, high surface energy, behaving faster translated rate, higher translating ability and selectivity to larger molecular, received considerable attention. The methods of synthesized small crystal - size ZSM - 5, different of modified approach and its advantage in the catalytic application were summarized.
