Description:
Plasma oxidation of benzene (C"6H"6) in oxygen and nitrogen was investigated using a dielectric barrier discharge (DBD) reactor with or without MnO"2 or TiO"2 at atmospheric pressure and without external heating except plasma heating. An alternative current power supply was used to generate corona discharges for the plasma oxidation. The energy density was controlled under 200J/L to keep an increase in gas temperature less than 167K. C"6H"6 was oxidized to carbon monoxide (CO) and dioxide (CO"2). Typically, the energy efficiency at an energy density of 92J/L was about 0.052, 0.039, and 0.024mol/kWh with MnO"2, TiO"2, and without MnO"2 and TiO"2, respectively. Benzene oxidation mechanism was mentioned. A comparison on energy efficiency as a function of initial concentration of hydrocarbons, inorganic sulphur compounds, and chloro (fluoro and bromo) carbons was given.
