Abstract： 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 was 71.7 kJ/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.
