In this study ZSM-5 Nano particles with high crystallinity were synthesized using a dry gel conversion technique. An L9 orthogonal array of the Taguchi method was applied to investigate the effect of synthesis parameters, such as crystallization time, gel drying temperature, molar composition of template (TPAOH) and water content in the crystallization stage on crystallinity and particle size of the ZSM-5 catalyst. The products were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). Beside short crystallization time, the particle sizes were considerably smaller in comparison with those prepared using the hydrothermal method. The results showed that the particle size and crystallinity increased with increasing water content and crystallization time. The effects of gel drying temperature and molar composition of template were found to be more complex, however. Comparing to hydrothermal method, ZSM-5 samples synthesized with the dry gel conversion exhibited higher selectivity to gasoline than other hydrocarbons.

在这项研究中，使用干凝胶转化技术合成了具有高结晶度的ZSM-5纳米颗粒。使用Taguchi方法的L9正交阵列来研究合成参数，如结晶时间，凝胶干燥温度，模板的摩尔组成（TPAOH）和结晶阶段的水分含量对ZSM-C结晶度和粒径的影响5催化剂。通过X射线衍射（XRD）和扫描电子显微镜（SEM）表征产物。除了短的结晶时间外，与使用水热法制备的那些相比，其粒径要小得多。结果表明，随着水含量和结晶时间的增加，粒径和结晶度增加。然而，发现凝胶干燥温度和模板的摩尔组成的影响更为复杂。与水热法相比，通过干凝胶转化合成的ZSM-5样品对汽油的选择性比其他碳氢化合物高。
