Catalytic fast pyrolysis (CFP) is a promising technology that can allow the conversion of biomass into transportable fuels. Despite its advantages in terms of simplicity and economic efficiency, the CFP of biomass has not been commercially applied. One of the biggest challenges is the precise design of highly effective zeolite catalysts tailored for biomass CFP, and the structure–property relationship of the zeolites in biomass pyrolysis is yet to be fully understood. Therefore, this review describes the key role of zeolites in the CFP of lignocellulosic biomass. First, a brief introduction of the chemistry of biomass pyrolysis is included to provide a basic understanding of the requirements for catalysts employed in CFP. Characteristic zeolite parameters such as porosity, acidity, and porosityacidity interplay that can affect the biomass pyrolysis routes are summarized. Furthermore, to explore the next-generation catalysts, the catalytic behaviors of metal-loaded, hierarchical, layered, and nanosized zeolites in biomass CFP are discussed and evaluated. Unresolved issues in zeolite designing are also highlighted. Finally, perspectives on the future developments of zeolite catalysts for biomass CFP are presented.

木质纤维素生物质的催化快速热解:沸石催化剂的关键作用

催化快速热解(CFP)是一种有前途的技术,可以使生物质转化为可运输的燃料。尽管在简单性和经济效率方面具有优势,但是生物质的CFP尚未商业应用。最大的挑战之一是为生物质CFP量身定制的高效沸石催化剂的精确设计,而且在生物质热解中沸石的结构-性质关系尚待充分理解。因此,本综述描述了沸石在木质纤维素生物质的CFP中的关键作用。首先,包括对生物质热解化学的简要介绍,以提供对CFP中所用催化剂要求的基本了解。沸石的特性参数,例如孔隙度,酸度和孔隙度总结了影响生物质热解路线的酸性相互作用。此外,为探索下一代催化剂,讨论并评估了金属负载的,分层的,分层的和纳米尺寸的沸石在生物质CFP中的催化行为。还强调了沸石设计中未解决的问题。最后,提出了关于生物质CFP沸石催化剂未来发展的观点。
