简介：Thebasic-nitrogenaromaticcompoundsinfeedstocksandliquidproductsfromthemicro-reactorandsolublecomponentsofcokeobtainedduringfluidcatalyticcracking(FCC)processwereanalyzedbythemicro-electrosprayionization(ESI)9.4TFouriertransformioncyclotronresonancemassspectrometry(FT-ICRMS)withanaveragemassresolvingpowerof300000atamassrangeof100-1200.Theanalyticalresultsrevealedthatthecokergasoil(CGO)containedahigherabundanceofbasic-nitrogenaromaticcompoundswiththetypeof-5Nto-9Ncomparedwiththoseindeasphaltedoil(DAO)andmixedFCCfeedstock.Aftercatalyticcracking,theabundanceoflowlycondensedbasic-nitrogenaromaticcompoundswasmuchlessthanthoseofhighlycondensedaromaticsintheliquidproducts,withthecarbonnumbermainlyrangingfrom6to25andtheaveragecarbonnumberoftheside-chainsequatingto1-5.Onthecontrary,withrespecttothesolublecomponentsofcoke,theabundanceoflowlycondensedbasic-nitrogenaromaticcompoundswasmorethanthoseofhighlycondensedaromatics,andthecarbonnumberrangedfrom12to30,whichwasmuchsmallerthanthatofthemixedFCCfeedstockbutslightlylargerthanthatofthecrackedliquidproducts.TheseresultshaveprovidedsomefundamentalinformationonFCCprocess.
