In this work, hierarchical ZSM-5 zeolites were prepared by a hard template method (pre-crystallization and dry gel) using sucrose to obtain suitable mesopores for the catalytic fast pyrolysis (CFP) of cellulose to produce aromatics. As the sucrose added decrease, the mesopore surface area and mesopore volume of the zeolites decreased while the micropore surface area and micropore volume increased. The mesoporous structure introduced by sucrose promoted the CFP of cellulose to aromatics by increasing the mass transfer of molecules. The highest aromatic yield of 37.0% was obtained over the hierarchical ZSM-5 zeolites prepared by the pre-crystallization method with sucrose/SiO₂ = 0.15.

在这项工作中，使用蔗糖通过硬模板方法（预结晶和干凝胶）制备了分层的ZSM-5沸石，以获得合适的介孔用于纤维素的催化快速热解（CFP）以生产芳族化合物。随着蔗糖添加的减少，沸石的中孔表面积和中孔体积减小，而微孔表面积和微孔体积增加。蔗糖引入的中孔结构通过增加分子的质量转移而促进了纤维素向芳族化合物的CFP转化。在通过蔗糖/ SiO ₂  ＝ 0.15的预结晶方法制备的分级ZSM-5沸石上，获得最高的芳族产率37.0％。
