ZSM-5 is a promising catalyst for the catalytic fast pyrolysis (CFP) of biomass due to its high selectivity to light hydrocarbons. However, rapid deactivation of catalyst has been a major challenge towards the commercialization of CFP. The objective of our study is to evaluate the performance of MCM-41/ZSM-5 composites during the CFP of biomass. Here, for the first time, we report the synthesis of a unique MCM-41/ZSM-5 composite via a one-step, facile aerosol-based method. The composition of ZSM-5 in the composites was varied and the prepared composites were used as catalysts for the in-situ and ex-situ CFP of miscanthus × gigantus. The prepared composites were characterized by N₂ adsorption-desorption, XRD, SEM, TEM and DRIFTS-pyridine adsorption. The results of CFP experiments demonstrated that ZSM-5 in the composites was fully accessible. Most importantly, MCM-41 acted as a sacrificial layer for coke deposition and decreased the deactivation rate of the ZSM-5.

ZSM-5由于对轻烃的高选择性，是用于生物质催化快速热解（CFP）的有前途的催化剂。然而，催化剂的快速失活已经成为CFP商业化的主要挑战。我们研究的目的是评估生物量CFP期间MCM-41 / ZSM-5复合材料的性能。在这里，我们首次报告了通过一步式，基于气溶胶的简便方法合成独特的MCM-41 / ZSM-5复合材料的方法。ZSM-5在复合材料中的组合物改变，并且所制备的复合材料中用作催化剂的原位和易地芒草×gigantus的CFP。制备的复合材料的特征在于N ₂吸附-解吸，XRD，SEM，TEM和DRIFTS-吡啶吸附。CFP实验的结果表明，复合物中的ZSM-5是完全可及的。最重要的是，MCM-41充当了焦炭沉积的牺牲层，并降低了ZSM-5的失活率。
