The epoxidation of propylene with H2O2 catalyzed by a supported TS-1 catalyst in a fixed-bed reactor has been studied. The effects of methanol concentration (40-70 wt.%), hydrogen peroxide concentration (520 wt.%), propylene pressure (0.2-0.6 MPa) and temperature (35-50 degrees C) on the reaction are investigated. The experimental results show that the reaction rate increases with the increase in methanol concentrations, hydrogen peroxide concentrations, propylene pressure and temperature; the activation energy of the reaction is 46.8 kJ mol(-1) and the reaction orders with respect to hydrogen peroxide and propylene are 032 and 0.68, respectively. The reaction was modeled with Eley-Rideal (E-R) and Langmuir-Hinshel-wood (L-H) models, and the results show that the kinetic model of Eley-Rideal with H2O2 being adsorbed can give the best fit among the models compared for the epoxidation of propylene with H2O2.
