摘要：

Removal　of　toluene　by　the　combination　of　non-thermal　plasma　(NTP)　and　various　catalysts　was　investigated　in　this　study.　Self-made　wire-cylinder　dielectric　barrier　discharge　(DBD)　reactor　energized　by　AC　power　supply　was　used　in　our　experiment.　Specific　energy　density　(SED),　energy　efficiency　(EY)　and　O3　concentration　of　different　reactor　were　investigated.　The　better　catalyst　was　chosen,　catalyst　stability　test　was　carried　out,　and　the　by-products　in　the　reaction　were　determined　and　analyzed.　The　results　show　that　compared　with　γ-Al2O3,　V2O5-TiO2/γ-Al2O3　catalysts　can　enhance　the　conversion　of　toluene,　decrease　SED　and　O3　concentration　and　enhance　EY.　Stability　test　of　V2O5-TiO2/γ-Al2O3　catalyst　show　that　toluene　conversion　decreases　slowly　with　the　reaction　time,　which　indicates　that　the　catalyst　suffers　slow　deactivation,　probably　due　to　the　accumulation　of　by-products　over　the　catalyst　surface.　After　calcinations　in　air　for　3　h　at　500℃,　activity　of　the　catalyst　can　be　recovered.　©,　2015,　Beijing　University　of　Technology.　All　right　reserved.
