The ever‐growing need to increase the efficiency of crude oil refining raises the prospects for utilizing advanced catalytic materials to supply increasing global demands for fine chemicals and petrochemicals. Zeolites have been used as indispensable catalysts in many commercial refining processes. Among them, zeolite beta is one of the most widely produced zeolite materials with industrial significance due to its large micropores and three‐dimensional pore structures. This article discusses recent progress on hierarchical beta zeolites from various synthetic strategies. Using zeolite beta as a representative case, we provide an overview on key aspects that are applicable to different zeolites via a variety of topics, such as selection of different template materials, tailoring of mesopore sizes by base leaching, organotemplate‐free synthesis of hierarchical zeolites, and selective desilication. This article concludes with a perspective on the design of scalable hierarchical zeolites that are more relevant as industrial catalysts in commercial processes.

分层β沸石的合理设计:概述及其他

对提高原油精炼效率的不断增长的需求提高了利用先进的催化材料来满足全球对精细化学品和石化产品日益增长的需求的前景。沸石已在许多商业精制过程中用作必不可少的催化剂。其中,β沸石由于其大的微孔和三维孔结构而成为具有工业重要性的最广泛生产的沸石材料之一。本文讨论了来自各种合成策略的分级β沸石的最新进展。以β沸石为代表的案例,我们通过各种主题概述了适用于不同沸石的关键方面,例如选择不同的模板材料,通过碱浸法定制中孔尺寸,无有机模板的分级沸石合成和选择性脱硅。本文以可伸缩的分级沸石的设计为结尾,该沸石与商业流程中的工业催化剂更相关。
