摘要
由于沸石分子筛在多个领域被广泛应用,高效可靠的沸石合成方法早已成为人们研究的重点。相较于传统高压釜水热间歇合成方法,沸石的连续流动相合成方法晶化时间短,时空产率高,是近年来发展的沸石合成新路线。利用连续流动反应器(CFR)的热延迟效应低、传质效果好和方法拓展性强等特点,可以在分钟级乃至秒级时间内实现高结晶度沸石合成,大大提升了合成效率和可控度。基于近期该领域的进展,本文介绍了沸石的连续流动反应器结构,其合成过程优势和产物特点及受限之处,并对其未来应用加以展望。
Due to the wide applications of zeolites in various fields,efficient and reliable synthesis of zeolite has become an important research issue.Compared with traditional high-pressure hydrothermal batch synthesis,continuous flow synthesis is one of the new methods for fast preparation of zeolite owing to its short crystallization time and high space-time yield.The high crystalline zeolites can be harvested in minute-and even second-level thanks to the specific characteristics of continuous flow reactors(CFR),such as low thermal lag,controllable mass transfer and good expansibility,which significantly enhance the synthesis efficiency and controllability.In this paper,based on the recent progress,the component of CFR equipment,the advantages and limitations of CFR for zeolite synthesis,and the future applications are introduced and prospected.
