应用结构参数及官能团浓度计算法对抚顺、茂名页岩油３５０～４５０℃和＞４５０℃馏分的平均结构组成进行计算，以大致表征这两种页岩油馏分的化学结构性质。结构参数计算结果表明，茂名页岩油较抚顺页岩油有较高的芳碳率及芳烃缩合度。官能团浓度计算结果表明，茂名页岩油较抚顺页岩油含有稍多的杂原子化合物（如噻吩、酚类）和多环芳烃，而抚顺页岩油较茂名页岩油则含有更多的饱和烃和单环芳烃。两种计算结果都表明，页岩油＞４５０℃馏分较３５０～４５０℃馏分含有更多的多环芳烃、杂原子化合物等组分。
The average structural composition of the fractions of 350 ~ 450 ℃ and> 450 ℃ in Fushun and Maoming shale oil was calculated by using structural parameters and concentration of functional groups to characterize the chemical structure of the two shale oil fractions. The calculation results of structural parameters show that Maoming shale oil has higher aromatic carbon ratio and aromatic condensation degree than that of Fushun shale oil. Concentration calculation of functional groups shows that the Maoming shale oil contains slightly more heteroatom compounds (such as thiophene and phenols) and polycyclic aromatic hydrocarbons (PAHs) than the Fushun shale oil, whereas the Fushun shale oil contains more saturated Hydrocarbons and monocyclic aromatic hydrocarbons. Both results show that the shale oil> 450 ℃ fraction contains more PAHs, heteroatom compounds and other components than the 350 ~ 450 ℃ fraction.
