Abstract

A hybrid system comprising silent discharge plasma (SDP) and manganese oxide (MnO2) catalyst was used for the decomposition of benzene in air, The efficiency for the benzene decomposition was greatly enhanced by combining MnO2 with the SDP reactor in the latter part. The MnO2 catalyst decomposed benzene by using ozone, which was formed in SDP as the oxidant precursor. With increase in the amount of water vapor in air, the efficiency for the benzene decomposition was decreased, partly due to the diminished formation of O3 in the SDP reactor. Only CO2 and CO were obtained as the products. The carbon mass balance was not perfect due to the formation of intermediates on MnO2 during the reaction. The intermediates were subsequently decomposed to CO2 and CO by MnO2 in the presence of O3. In dry air, the selectivities to CO2 and CO were 70% and 30%, respectively, and were almost independent of SED. The CO2 selectivity was improved to 90% by humidifying the reaction gas.
