A　series　of　experiments　was　performed　for　toluene　removal　from　a　gaseous　influent　at　the　normal　temperature　and　atmospheric　pressure　by　decomposition　due　to　dielectric　barrier　discharge　generated　non-thermal　plasma,　by　using　MnO2/gamma-Al2O3　as　catalyst.　The　removal　efficiency　of　toluene　was　significantly　increased　by　combining　MnO2/gamma-Al2O3　With　NTP.　At　the　same　time,　the　goal　of　improving　energy　efficiency　and　decreasing　O-3　from　exhaust　as　treatment　was　accomplished　(c)　2008　Elsevier　B.V.　All　rights　reserved.
