摘　　要：气–液/液–液两相体系广泛存在于多种化工过程中,如精馏、吸收、萃取、多相反应等.传统宏观的两相接触方式存在接触面积小、传质效率低、反应速率慢等问题,而微液滴具有比表面积大、生成频率高、液滴系统相对独立等诸多优点,可极大强化相间传质和化学反应.将微液滴作为传质和反应的媒介,能够有效改善两相宏观接触的局限,已被广泛应用于各类化工单元操作中.本文综述了近年来关于微液滴强化相间传质与多相化学反应的研究进展,并对未来的研究方向进行了展望.Gas-liquid or liquid-liquid two-phase systems are widely encountered in chemical processes,such as distillation,absorption,extraction,multiphase reaction.Conventional macroscopic contact mode between two phases suffers from issues such as small contact area,low mass transfer efficiency and slow reaction rate.Microdroplets are considered as an effective approach to solve these problems owing to the advantages of large surface area,high generation frequency and relatively independent droplet systems,which could greatly intensify interphase mass transfer and chemical reaction.As a medium of mass transfer and reaction,microdroplets can effectively improve the limitation of two-phase macroscopic contact and have been widely used in various chemical unit operations.This article provides a comprehensive overview of the research progress in the field of microdroplet-based enhancement of mass transfer and chemical reaction.The prospects for future studies on the field are also given.
