多相反应体系的微界面强化简述
Overview of microinterface intensification in multiphase reaction systems
摘要
Abstract
Gas-liquid systems with low reaction rates such as hydrogenation and oxidation are widely present in modern industrial processes.These reactions are generally controlled by mass transfer.Therefore, mass transfer intensification in multiphase reaction systems has been one research hotspot in chemical engineering.Except studies on reactors intensified by external field or micro-channel (micro-fluidics), most studies were focused on traditional reactors with interface scale of millimeter to centimeter by means of stirring and mixing, bubble size distribution, flow pattern, and structure-effect relationship.It has rarely been studied how to build a microinterface system and to evaluate its effects in reactors with a diameter of several meters.In this paper, the microinterface reaction intensification in heterogeneous systems was discussed.The micro-interface definition, microinterface reaction intensification, structure-effect regulation, structure and formation principle of microinterface reactors, techniques of microparticle measurement and interface characterization were briefly described.The challenges and problems in microinterface reaction intensification was also presented for discussion.关键词
