Conversion of NO with a catalytic packedbed dielectric barrier discharge reactor-中国期刊网

摘要 Thispaperdiscussestheconversionofnitricoxide(NO)withalow-temperatureplasmainducedbyacatalyticpacked-beddielectricbarrierdischarge(DBD)reactor.Aluminaoxide(Al_2O_3),glass(SiO_2)andzirconiumoxide(ZrO_2),threedifferentsphericalpackedmaterialsofthesamesize,wereeachpresentintheDBDreactor.TheNOconversionundervaryinginputvoltageandspecificenergydensity,andtheeffectsofcatalysts(titaniumdioxide(TiO_2)andmanganeseoxide(MnOx)coatedonAl_2O_3)onNOconversionwereinvestigated.TheexperimentalresultsshowedthatNOconversionwasgreatlyenhancedinthepresenceofpackedmaterialsinthereactor,andthecatalyticpackedbedofMnOx/Al_2O_3showedbetterperformancethanthatofTiO_2/Al_2O_3.Thesurfaceandcrystalstructuresofthematerialsandcatalystswerecharacterizedthroughscanningelectronmicroscopyanalysis.ThefinalproductswereclearlyobservedbyaFouriertransforminfraredspectrometerandprovidedabetterunderstandingofNOconversion.
