摘要
减压渣油组分的同步荧光光谱能够较好地反映出各极性和芳香度不同的组分的芳香环系大小。平均来说，减压渣油的芳香分中的芳香结构以２～４环为主，胶质中的芳香结构以３～５环为主。
The synchronous fluorescence spectra of separated fractions of vacuum residua were investigated.The results show that the aromatic structures of vacuum residue fractions with different polarity and aromaticity can be distinguished by their synchronous flourescence spectra.Number of aromatic rings in aromatics,resins and asphaltenes in average aromatic systems are about 2～3,3～5 and more than 5,respectively.
