Molecular Characterization of Hydrotreated Atmospheric Residue Derived from Arabian Heavy Crude by GC FI/FD TOF MS and APPI FT-ICR MS-中国Betway体育网页登陆

摘要 HighresolutionmassspectrometryincombinationwithdistillationandSARAfractionationprovidesusanopportunityforin-depthunderstandingaboutthehydrotreatingprocessatthemolecularlevel.Inthisstudy,theatmosphericresiduederivedfromArabianheavycrudeanditshydrotreatedproductswereinitiallysubjectedtodistillationandSARAfractionation.ThesaturateswerecharacterizedbyGCFI/FDTOFMS.ThearomaticsandresinswerecharacterizedbyAPPIFT-ICRMS.Compositionalchangesofdifferentcompounds(paraffins,naphthenes,aromatichydrocarbons,andheteroatomiccompounds)containedindifferentdistillates(vacuumgasoil,vacuumresidue)wereobtained.Moredetailedknowledgeaboutthehydrotreatingprocesswasachieved.
