Abstract

Procédé de traitement d'une charge gazeuse contenant du dioxygène et un ou plusieurs composés volatils, lequel procédé comprend les étapes suivantes : a) on met en contact ladite charge gazeuse contenant du dioxygène et un ou plusieurs composés organiques volatils avec un monolithe comprenant de la silice et du dioxyde de titane, ledit monolithe comprenant un volume macroporeux de type I, dont le diamètre des pores est supérieur à 50 nm et inférieur ou égal à 1000 nm, compris entre 0,1 à 3 mL/g, et un volume macroporeux de type II, dont le diamètre des pores est supérieur à 1 µm et inférieur ou égal à 10 µm, compris entre 1 à 8 mL/g ; b) on irradie ledit monolithe par au moins une source d'irradiation produisant au moins une longueur d'onde inférieure à 400 nm pour convertir lesdits composés organiques volatils en dioxyde de carbone, ladite étape b) étant réalisée à une température comprise entre - 30 °C et + 200°C et à une pression comprise entre 0,01 MPa et 70 MPa.
