Co-treatment of industrial air streams using A.O.P. and adsorption processes
Coupling adsorption with two different photochemical oxidation methods was investigated, in order to treat industrial gaseous effluents containing a low concentration of Volatile Organic Compounds (VOC). Prior to adsorption/photocatalysis cyclic study, new TiO2 based catalysts were prepared by impre...

| description | Coupling adsorption with two different photochemical oxidation methods was investigated, in
order to treat industrial gaseous effluents containing a low concentration of Volatile Organic Compounds
(VOC). Prior to adsorption/photocatalysis cyclic study, new TiO2 based catalysts were prepared by impregnating
commercial zeolites in pellets form using a sol-gel technique. Scanning Electronic Microscopy observations
linked to BET and adsorption equilibrium measurements of two VOC (1-butanol or BuOH and
methyl-ethyl-ketone or MEK) showed that TiO2 happened to fix on the inert binder, without significant modification
of support properties. A specific diffusion cell was used to produce dilute polluted air streams for
each VOC in dynamic experiments, in which adsorption and photodegradation phases were alternatively
carried out. Adsorption/photocatalysis co-treatment unable the total degradation of BuOH, and the regeneration
of adsorbent. When using V-UV photolysis, pure zeolites were used, irradiated at 172 nm with an
xenon excimer lamp. Excellent results were observed, since a total and rapid degradation was obtained for
both VOC, especially thanks to a determining role of ozone. |
