Catalytic Decomposition of Toluene Using Various Dielectric Barrier Discharge Reactors

【摘要】 <正> Decomposition of toluene was experimentally investigated with various dielectricbarrier discharge （DBD） reactors,such as wire-cylinder,wire-plate and plate-to-plate,combinedwith multi-metal oxides catalyst （Mn-Ni-Co-Cu-Ox/Al₂O₃） loaded on the cordierite honeycomband nickel foam,respectively.The effects of some factors including the residence time,reactorconfiguration and catalyst,upon the toluene destruction were studied.Results revealed thatthe use of in-plasma catalysis was more helpful to enhancing the DRE （destruction and removalefficiency） and reducing the O₃ formation than that of either post-plasma catalysis or plasmaalone.It was demonstrated that the wire-plate reactor was favorable for the oxidation reaction oftoluene and the nickel foam-supported catalysts exhibited good activity.更多还原
