对非等体积四塔串联鼓泡塔氧化反应器，体积大的反应器放置在前面的排列顺序有利于得到高的出口CHP浓度。

Aiming at the four-serial non-equal volume bubble reactors , that the bigger reactors are front is better than that the lesser reactors are font , which can improve the product of CHP .

本论文的工作之二是对四塔串联鼓泡塔氧化反应器进行了稳态模拟。

The second topic is the steady-state simulation of four-serial bubble reactors of the oxidation process .
