摘　　要：在大港减压渣油超临界萃取物（DVRSFEF）的GC／MS分析检测中，除了大港减渣1级萃取分F1以外，在其他级分中分析检测出的物种和数量均较少，特别是DVRSFEF10～SFEF17的检测结果很不理想。故通过层析柱对DVRSFEF按照标准分析方法进行分离，可以得到饱和分、芳香分、胶质和沥青质在DVRSFEF中的分布规律，以及DVRSFEF所含饱和分、芳香分、胶质和沥青质中链烃、环烷烃和芳烃的含量的变化规律；还检测出了具有高附加值的稀有物质。DVR SFEF 1-16＇s main molecular composition have been qualitatively and quantitatively ana- lysed by GC/MS except DVR SFEFI. The results show that species and its quantity detected are less. These detectable results in total ion chromatogram are not good, especially DVR SFEF 10 to SFEF 17. DVR SFEF was respectively separated into saturated hydrocarbon, arene, gum and asphaltine by such a standard technique column chromatography in which these solvents containing n-heptane, petroleum ether,benzene,benzene-alcohol. Detected species and content in DVR SFEF residue are more than those of non-separable samples. In separable samples many compounds containing hetero-atoms have also been detected.
