Oxidation of xylene and its irradiation-induced organic byproducts in air using Ag-loaded TiO (Ag/TiO) beds was studied under electron beam (EB) irradiation. The Ag/TiO beds were placed in an irradiation or a non-irradiation space in order to identify the oxidation of xylene/its byproducts by EB irradiation, by catalytic process, and by a combination of the two. Placement of the Ag/TiO bed to the irradiation space resulted in the suppression of xylene decomposition. On the other hand, production of CO was observed in the gas phase of the irradiation space and on the surface of the Ag/TiO pellets placed both in the irradiation and non-irradiation spaces. The concentration of CO became higher when the layer was placed in the non-irradiation space. The production of CO was enhanced by loading of Ag to the TiO pellet surface. The highest concentration of CO was obtained for Ag/TiO with Ag contents greater than 5wt%.
