摘　　要：反应精馏技术是过程强化概念在化学工业成功应用的典范。由于反应与精馏耦合的高度复杂性和非线性,反应-精馏相互影响机制、耦合方式及其过程能效调控与优化成为制约该技术广泛应用的关键科学问题。综述了近二十年来国内外反应精馏技术从基础研究到工业应用的概况,包括反应精馏过程的可行性分析与概念设计方法、稳态模拟过程优化与动态模拟控制策略设计、兼具催化反应与气液传质的高效内构件开发以及反应精馏在各领域的应用。探讨了目前制约反应精馏广泛应用关键问题的解决方法与途径,阐明了普适性的反应精馏过程开发方法,总结了基于反应精馏过程耦合的新型过程强化技术,指出了反应精馏技术的发展趋势。Reactive distillation is one of the typical applications of process intensification concept in chemical engineering. Since the coupling of reaction and separation is highly complex and nonlinear, the effect mechanism of reactive and distillation, coupling method and regulation and optimization for the reactive distillation process is a key for the industrial applications. The general situation of RD technology at home and abroad in recent twenty years is reviewed, from fundamental research to industrial application, including the feasibility analysis of RD process and the method of conceptual design, the optimization of steady state simulation process and the design of dynamic simulation control strategy, the development of efficient internal components which have both the reaction catalysis and mass transfer function as well as the industrial application of RD technology in various fields. Possible solutions to these keys which restrict the wide application of RD technology are discussed. The universal development method of RD process and the new process intensification technology based on RD process are summarized, then the trend of RD technology are pointed out.
