Contribution à l'élaboration d'un papier photocatalytique. Application à la réduction des COVs

Abstract : This study corresponds to a PhD thesis with financial of the Ministry of Research. The objectiveof this work is to elaborate a based-paper titanium/silica photocatalysis for on stream flue gasdepollution (volatile organic compounds) stemming from processes of printing. The volatileorganic compound used in this study is the Ethanol. Particles of hollow silica were synthesizedand used as a support for nano particles of titanium dioxide, which were elaborated by sol-gelmethod. A continuous reactor was designed and used to treat the polluted gaseous flow. Theethanol passes through the photocatalytic paper irradiated by a UV lamp. Several photocatalyticspapers were elaborated and characterized by several techniques (MEB, Spectroscopy Raman,DRX).A modeling of the reactor and the support (photocatalytic paper) was developed and proposed.This modeling integrates the Langmuir – Hinshelwood kinetic and the variation of the intensitywith position in layer’s paper using the Kublka-Munk model.
