An　experimental　study　on　VOCs　removal　with　non-equilibrium　plasma　generated　by　the　combination　of　corona　discharge　and　dielectric　barrier　discharge　was　carried　out.　Toluene　was　chosen　as　the　target　contamination　in　the　experiment.　In　order　to　optimize　the　geometry　of　the　non-thermal　plasma　reactor,　the　removal　efficiency　of　toluene　was　compared　for　various　inner　electrode　diameters　(1.20　mm,　1.65　mm,　2.0　m　respectively),　different　reactor　materials　(ceramic　and　PMMA),　the　presence　and　absence　of　ceramic　raschig-ring　packing.　In　addition,　electricity　parameters　during　the　discharge　process　were　measured　under　the　experimental　condition.　Experimental　results　showed　that　toluene　removal　ratio　increased　significantly　with　increasing　the　voltage.　With　respect　to　toluene　conversion,　the　smaller　size　electrode　was　slightly　superior　to　the　bigger　size　electrode　when　the　voltage　was　low.　However,　the　reverse　was　the　case　with　further　increase　in　voltage.　Under　the　same　experimental　conditions,　the　removal　efficiency　of　toluene　with　ceramic　reactor　was　higher　than　that　with　PMMA　reactor.　Obviously,　the　removal　of　toluene　was　enhanced　by　filling　some　dielectric　in　the　reactor.　In　the　presence　of　ceramic　raschig-ring　packing,　the　convection　was　remarkably　improved　against　in　absence　of　padding.　The　discharge　power　during　plasma　processing　to　decompose　toluene　was　measured　using　the　U-Q　Lissajous　diagram.　It　was　proved　that　the　degradation　of　toluene　with　non-equilibrium　plasma　consumed　less　energy　compared　with　other　methods,　and　increasing　discharge　power　was　beneficial　to　toluene　removal.
