KINETICS AND MODELING OF BENZENE OXIDATION

Abstract

The gas phase oxidation of benzene over a V₂O₅ + P₂O₅ + MoO₃ + Sb₂O₃ catalyst supported on kieselguhr carrier is studied at the temperature range 344–393^°C. 14 different kinetic models are tried to determine the mechanism of benzene oxidation. It is shown that benzene oxidation takes place via a two step redox mechanism which is first order with respect to benzene and 1/2 or 1st order with respect to oxygen. Rate constants for both models are presented.
