摘要
Decomposition of toluene was experimentally investigated with various dielectric barrier discharge （DBD） reactors, such as wire-cylinder, wire-plate and plate-to-plate, combined with multi-metal oxides catalyst （Mn-Ni-Co-Cu-Ox/Al2O3） loaded on the cordierite honeycomb and nickel foam, respectively. The effects of some factors including the residence time, reactor configuration and catalyst, upon the toluene destruction were studied. Results revealed that the use of in-plasma catalysis was more helpful to enhancing the DRE （destruction and removal efficiency） and reducing the O3 formation than that of either post-plasma catalysis or plasma alone. It was demonstrated that the wire-plate reactor was favorable for the oxidation reaction of toluene and the nickel foam-supported catalysts exhibited good activity.
