采用制备液相色谱法，以硅胶或氧化铝作为吸附剂，对大庆、胜利混合减压馏分油和大庆减压渣油进行了族组分的制备分离，然后用同步荧光光谱法分析了一些族组分中的芳烃环分布，用气相色谱法分析了一些族组分中的正构烷烃分布。结果表明，由于氧化铝吸附重质油中的长链正构烷烃的能力较强，使得芳烃组分中混有长链正构烷烃。硅胶虽然不会对重质油中的长链正构烷烃产生强吸附，但分离减压馏分油时饱和烃组分中混有一环、二环芳烃；分离减压渣油时饱和烃组分中除混有一环、二环芳烃外，还会有三环和三环以上芳烃。考察了色谱柱温、氧化铝水含量及进样量对氧化铝分离重质油族组分的影响，并讨论了它们对重质油族组成定量分析准确度的影响。
Using preparative liquid chromatography and silica gel or alumina as adsorbents, the components of Daqing, Shengli vacuum oil and Daqing vacuum residue were separated and prepared. Then some groups were analyzed by synchronous fluorescence spectrometry The aromatic ring distributions in the components were analyzed by gas chromatography for the n-alkanes distribution in some of the family components. The results show that due to the strong ability of alumina to adsorb long-chain normal paraffins in heavy oil, the long-chain normal paraffins are mixed with the aromatic components. Although silica gel does not produce strong adsorption of long-chain normal paraffins in heavy oil, when the vacuum distillation oil is separated, the saturated hydrocarbon components are mixed with a ring and the bicyclic aromatic hydrocarbons; when separating the vacuum residue from the saturated hydrocarbon components In addition to mixed with a ring, bicyclic aromatics, there will be tricyclic and tricyclic aromatic. The effects of column temperature, alumina water content and injection volume on the fractionation of heavy oil components by alumina were investigated. Their effects on the quantitative analysis of heavy oil components were also discussed.
