The Effect of Catalyst on the Decomposition of Dilute Benzene Using Dielectric Barrier Discharge
E-mail:
One of the effective methods for removal of volatile organic compounds (VOCs) is using the combination of non-thermal plasma discharge and catalyst. The experiments were conducted to investigate benzene decomposition in air stream by dielectric barrier discharge (DBD)-catalyst hybrid system. Several types of catalysts such as TiO2 (JRC-TIO5), Pt/TiO2 and V2O5/TiO2 had been selected and attached on one glass barrier in the DBD plasma reactor to investigate the catalytic activities. Non-thermal plasma chemical decomposition of dilute benzene was investigated at different range of discharge voltage and residence time at atmospheric pressure. It is shown that the DBD and 1 wt% V2O5/TiO2 catalyst hybrid system is the effective method in decomposing benzene in air stream and controlling byproducts such as CO, CO2 and N2O at the same discharge voltage and gas residence time.
