Procédés d'élimination photocatalytique de COVs

Abstract : This work deals with the kinetics investigation of the photocatalytic degradation of VOCs as methanol, trichloroethylene and particularly benzene, in order to build and design a photocatalytic reactor. Fundamental parameters have been studied with the help of an appropriate experimental set-up. Methanol and trichloroethylene follow the Langmuir-Hinshelwood kinetics model. The benzene degradation involves a catalytic surface deactivation due to islands of intermediates strongly bound to the surface. The pathway and mechanism of benzene degradation have been established using conversion data versus time as weil as the measurement of reaction products. A model, based on a heterogeneous kinetics law about the growth of the islands and on the Langmuir-Hinshelwood model, has been developed in order to explain and confirm the particular behavior of benzene.
