摘要
本文给出线性复杂反应系统的表现速率矩阵与内禀速率矩阵之间的关联式,指出表观速率与内禀速率之间的差别反映扩散对反应的影响。接着研究复杂反应受扩散影响时的一些值得注意的特点,如虚反应和“拉平效应”。最后利用适当的线性模型剖析了ZSM5型催化剂上甲苯烷基化反应的择形机制。
The relation formula between apparent rate matrix and intrinsic rate matrix of linear complex reaction system was given. It was pointed out that the difference between apparent rates and intrinsic rates reflectcd the influence of diffusion on reactions. Some notable characteristics of complex rcaction when influcenced by diffusion, such as unreal reaction path and 'even up effect', were discusscd. At last thc shape-selectivity mechanism in toluene alkalation over ZSM5 was analyscd with the aid of a suitable linear model.
