摘要
综述了各种催化精馏塔及其内构件,包括拟固定床式、填料式、悬浮颗粒式和背包式等;介绍了催化精馏过程的各种模拟计算方法,如级模型、微分模型、人工神经网络模型和商用软件在模拟过程中的应用,并简要叙述了催化精馏技术的开发现状、工业应用状况以及与其他先进技术耦合研究的情况。集精馏填料和催化剂于一体的整体填料的催化精馏内构件以及高活性、高选择性、长寿命催化剂的研究是催化精馏技术进一步发展的研究重点。
Different catalytic distillation columns and their internal components, namely pseudo fixed bed type, packing type, suspension type, external coupling reactor type and so on, are introduced. Simulation methods for the catalytic distillation, such as equilibriurn/nonequilibrium model, differential model and artificial neural network model, and application of commercial software to the simulation process are reviewed. The development of the catalytic distillation technique and its combination with the other advanced techniques are briefly described. The internal packings with catalyst coating and the long-life catalysts will be research points in future.
