催化反应精馏研究中的若干问题——(I)过程的主要影响因素和操作工艺

SEVERAL IMPORTANT ASPECTS IN CATALYTIC REACTIVE DISTILLATION ——(I)MAJOR INFLUENCING FACTORS AND OPERATIONAL TECHNOLOGY OF THE PROCESS

主要阐述并讨论了催化反应精馏（ 又称反应或催化精馏） 过程涉及的若干问题．如：化学平衡对相平衡的影响，化学平衡和相平衡的交互作用及进料对操作工艺的影响。

The major factors influencing reactive distillation were introduced and analysed. It is found that the effect of equilibrium chemical reaction on vapor-liquid phase equilibrium is considerably because of the co-existence of chemical reactions and phase equilibrium, and the operation of reactive distillation may become more difficult than that of conventional distillation due to the interaction between chemical reaction and vapor-liquid equilibrium, in additton, different feed locations may also cause different operating states . The packing mode of catalyst for the column is another important aspect for industrial catalytic distillation.
