摘　　要：为了获得对二甲苯氧化反应器的最大生产能力,采用反应器合成的方法对多个氧化反应器组成的网络进行了优化研究.在不改变现有装置及工艺条件情况下,考察了两类具有重要工业应用价值的反应器网络形式:主反应器串联预反应器网络和三釜混联反应器网络.运用混合逻辑非线性(MLNLP)方法对上述两类网络模型进行了求解,得到了优化的反应器组合形式和工艺条件.计算结果表明,在原有的主反应器前串联体积为主反应器体积8.4% 的平推流反应器,可提高28.9%的生产能力;将现有的三釜并联反应器调整为互联形式,可提高14.7%的生产能力.To maximize the production capability of p-xylene oxidation reactor, the method of reactor network synthesis was proposed to optimize network combinations of multi-reactors. Without changing the existing industrial equipments and process course, two network models of practical interest were taken into account. The first model was taken as the main reactor serried with a small pre-reactor, and the second model was taken as a network of interconnected three reactors. Mixed logic nonlinear programming （MLNLP） was employed to solve the two network models and obtain the optimal network configuration and operating condition. Computation results show that the addition of a plug flow pre-reactor of 8.4% volume of the main reactor lead to 28.9% production increase, and that an alternative connection among the existing three reactors from parallel mode result in 14.7% production enhancement.
