The emission of volatile organic compounds to the air is a big concern due to their hazardous health and environmental effects. One of the best methods to eliminate these compounds is catalytic oxidation of VOCs to convert them into CO2 and H2O, which is the most efficient and cost-effective. In this research work, the catalytic total oxidation of toluene at 200-500 °C in air over Pt/HZSM5-HMS catalysts has been investigated. Several kinetic models have been selected and tested to investigate the kinetics of this reaction. The obtained results showed that the power law (PL) model and Langmuir-Hinshelwood (LH) model were not appropriate to get the kinetics of toluene combustion over the catalyst. On the contrary, the Mars-van Kreleven (MVK) mechanism represent a good fit (R2 = 1) towards the experimental data and allowed to determine the kinetic parameters.
