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