Abstract:An Ag-SiO2 stationary phase was prepared and applied in solid phase extraction(SPE) technique to separate alkenes from FCC diesel fractions and coker diesel fractions.GCMS and 1H NMR were used to characterize the types and carbon number distributions of the separated alkenes.Test results showed that normal α-olefin,internal monoolefin,diolefin and cycloolefin were the main types of alkenes in FCC diesel fractions and coker diesel fractions.The mole fraction of internal-ene hydrogen in FCC diesel fractions was 80.41%,and the mole fraction of normal α-ene hydrogen in coker diesel fractions was 53.32%.The distributions of alkenes in FCC diesel fractions and coker diesel fractions were focused on C11—C15 and C12—C22,respectively.
Keywords:diesel  alkene  solid phase extraction  mass spectrometry analysis  nuclear magnetic resonance
