The intrinsic kinetics of ethylene oxidation in excess oxygen over supported platinum catalyst were determined in a spinning basket-type gradientless reactor, as well as in adiabatic and nonadiabatic fixed-bed reactors over a wide range of operating conditions. A comparison of the experimental results with various mathematical models of fixed-bed reactors showed that a one-dimensional two-phase model, including solid conduction, accurately predicted the behavior of the experimental fixed-bed reactor system. Related studies showed that high-temperature platinum catalysts pretreated with carbon monoxide are more active than oxygen-pretreated catalysts for carbon monoxide oxidation. There was no difference in the activity of catalysts pretreated in ethylene and those pretreated in oxygen for ethylene oxidation. Sustained isothermal oscillations were observed in the intrinsic rate of reaction for the partial and total oxidation of ethylene over supported silver catalysts.
