ResumoThe kinetics of propylene oxidation have been investigated over the temperature range of 325 to 475 °C. The apparent activation energies changed from 15 to 18 kcal/mole at high temperature (> 400 °C) to 43–53 kcal/mole at lower temperatures. The reaction orders for both oxygen and propylene also changed with temperature. It was found that these changes in the kinetic parameters could be completely explained in terms of the coupled kinetics of catalyst reduction and reoxidation.
