Photocatalytic degradation od VOC's has been investigated in a number of devices. An optimisation of this process requires a chracterisation of the reactor : in a first step the gas flow behaviour has to be studied (plug flow, CSTR,...) by RTD analysis; then, chemical kinetics have to be determined as a function ot the relevant parameters (space time, relative humidity, concentrations, etc). All the data collected lead to a reliable design of the equipment.Séminaire 2008 de l'Ecole Doctorale RP2E "Ingénierie des Ressources, Procédés, Produits et Environnement", Nancy : France (2008)Chemical Physicstext
