摘　　要：采用碳纳米管增强复合材料催化剂,在等温积分反应器中获得环氧乙烷非均相催化水合宏观反应动力学实验数据,建立了幂函数型宏观反应动力学方程,采用Levenberg-Marquardt法对动力学模型参数进行估算,并以该动力学模型为基础,分析了均温反应器的热稳定性。结果表明,生成乙二醇主反应的表观活化能为71.7 k J/mol,与两个典型的串联副反应的活化能接近。模型参数统计检验结果表明,该宏观动力学方程参数是适定的,可用于工业反应器的设计。给出的反应器关键参数的计算方法,可为乙二醇合成反应器的模拟计算和设计开发提供必要的依据。The experimental data of macrokinetics on heterogeneous catalytic hydration of ethylene oxide were obtained in an isothermal integral reactor by using carbon nanotube reinforced composite catalyst.The macrokinetic equation of power function model was established,and the kinetic parameters were estimated by Levenberg-Marquardt method.Based on the kinetic model,the thermal stability of the homogenous temperature reactor was analyzed.The results showed that the apparent activation energy of the main reaction of ethylene glycol was71.7kJ/mol,which was close to those of the two typical tandem side reactions.Statistical results of the model parameters indicated that these parameters of the macrokinetic equation were suitable and could be used in the design of industrial reactors.
