Abstract Hydrogen peroxide (H2O2) has the remarkable characteristics of strong oxidation, in which its vapour ([H2O2]g)has further advantages, such as economize and good light transmission. But there is very rare research about its degradation effect in Gas-Phase Advanced Oxidation (GPAO). In the present study, the photochemical oxidation for gas containing benzene series, using ultraviolet (UV) irradiation and [H2O2]g, was investigated in a transparent bag made of fluorinated ethylene propylene (FEP). Only UV or [H2O2]g hardly reduced the pollutant in 5 hours in which the reactor was also stable. With the high pollutant concentration (248 to 756 mg/m3) and short residence time (3S) compared with the related studies, studying the degradation of benzene, toluene and xylene, the apparent rate by UV/[H2O2]g/(powder active carbon, PAC) was higher compared with the different way (UV/[H2O2]g, UV/[H2O2]g/TiO2 and UV/[H2O2]g/ZnO), but it was found that the terminal degradation by UV/[H2O2]g significantly decreased, in which the conductivity decreased after reaction. The effects of increasing pollutant concentration and H2O2 pH were negative for the treament, but the UV radiated power positive till 40W. In addition, the characteristic absorbance for three benzene series showed that the key structure of pollutant molecule were damaged in GPAO.

Homogeneous Decomposition

Studies of the catalytic oxidation of benzene to maleic anhydride and carbon dioxide over vanadia/molybdena catalysts show that the major part of the reaction involves interacting gas and gas-solid processes. The results are consistent with a mechanism in which a benzeneoxygen adduct is formed catalytically, desorbs and then reacts to give maleic anhydride entirely in the gas phase. On the basis of this proposed mechanism, the kinetics of individual reactions have been investigated in some depth. The over-oxidation of maleic anhydride has been found to be not significant under the conditions of reaction. The kinetic relationships governing the homogeneous decomposition of the adduct and the oxidation of the adduct to maleic anhydride and to carbon dioxide have been established. The results show that essentially all of the anhydride originates from mixed gas-solid/gas reaction while substantial amounts of carbon dioxide are produced entirely catalytically.
