摘　　要：在建立合适的对二甲苯氧化反应动力学基础上,对工业氧化反应器进行了模拟计算。考察工艺参数对反应器转化率和收率的影响,分析了氧化系统稳定敏感性。结果表明,对二甲苯氧化转化率对气液界面面积的敏感性较强,在一定的操作范围内,系统呈现单一的稳定性。Simulation calculation was carried out on industrial oxidation reactor on the basis of building a suitable para-xylene oxidation reaction kinetics.The effects of technology parameters on reactor conversion rate and yield rate were investigated,the oxidation system stability sensitivity was analysed.The results showed that the sensitivity of gas-liquid interface area on para-xylene oxidation conversation rate is strong.In a certain operation range,the system appears a single stability.
