An electron-beam (EB) irradiation/catalytic oxidation system was developed for the purification of a volatile organic compounds (VOC) gas stream under a practical gas flow condition. This system consists of a compact-sized electron accelerator and an ozone decomposition catalyst, which is MnO$$_{2}$$. The decomposition of toluene and/or xylene and their mineralization were examined with and without catalytic oxidation for a gas stream at a flow rate of 500 Nm$$^{3}$$/h. A combined catalyst bed enhanced the decomposition of VOCs and the mineralization of VOC and its irradiation organic byproducts. For example, the mineralization ratio for a 5-ppmv toluene/xylene/air mixture increased from 42% by EB irradiation to 100% by the combination treatment at 9.3 kGy. Furthermore, the yield of CO$$_{2}$$ relative to CO$$_{x}$$ increased from 59% to 85% by this catalytic treatment.
