| 摘 要： | 采用柱色谱分离方法,分别以氧化铝(5g)、上部为氧化铝下部为硅胶(3g∶2g)、上部为硅胶下部为氧化
铝(3g∶2g)和硅胶(5g)4种填充方法对原油和沥青砂岩抽提物进行族组成分析,对其饱和烃馏分进行气相色
谱-质谱分析,对比剖析了饱和烃生物标志物组成特征。结果表明:这4种不同的填充方法对类异戊间二烯型烷
烃、藿烷、规则甾烷等生物标志物的分子组成影响一般均较小,但对于高碳数正构烷烃和重排甾烷等化合物的影
响则较明显。

| Abstract: | The fractions of crude oil and bituminous sandstone extract were separated by chromatographic columns
with four packed methods,that is,respectively,alumina(5 g), alumina(3 g)at the top and silica gel(2 g)in the
bottom, silica gel(3 g)at the top and alumina(2 g)in the bottom, silica(5 g). The saturated hydrocarbons
were analyzed by gas chromatography-mass spectrometry, and the compositions of biomarkers were compared.
The results show that the four column chromatographic methods yield slight affection to the distributions of
isoprenoid alkanes, tricyclic terpanes, hopanes and regular steranes in the saturated hydrocarbon fraction, but
apparent affection to the occurrence of high molecular weight n-alkanes and diasteranes. |
