摘要：

以理想反应器时间和空间特性为出发点,探讨了间歇操作釜式反应器(BR)、平推流反应器(PFR)和全混流反应器(CSTR)等理想反应器之间的内在联系,推导了循环操作PFR反应器的停留时间分布函数,分析了多段串联全混流反应器和循环操作PFR反应器在各理想反应器之间的桥梁和纽带作用。在此基础上,简要归纳了各理想反应器之间的联系。

关键词: 理想反应器, 时空特性, 内在联系, 循环操作平推流反应器, 停留时间分布

Abstract:

On the basis of spatial-temporal characteristic of ideal reactors, the inherent relations among the batch reactor, the plug flow reactor (PFR), and the continuous stirred tank reactor (CSTR) were discussed. Both the F and E functions of the recycle PFR reactor were derived. The role of CSTR in series or the recycle PFR as a bridge or a link among the ideal reactors was addressed. Based on the discussion, the relations among the ideal reactors were briefly summarized.

Key words: Ideal reactor, Spatial-temporal characteristic, Inherent relation, Plug flow reactor with recycle, Residence time distribution
