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)共4种填充方法对原油和沥青砂岩抽提物进行族组成分析,对其芳烃馏分进行气相色谱-质谱分析,对比剖析了芳烃分子标志物组成特征。结果表明,这4种不同的填充方法对萘、菲、二苯并噻吩、三芳甾烷等分子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。The fractions of crude oil and bituminous sandstone extraction were separated by chromatographic columns with four packing methods respectively,including alumina (5g),alumina: silica gel (3g∶2g,W∶W),silica gel: alumina (3g∶2g,W∶W) and silica (5g).The aromatic hydrocarbons were analyzed by gas chromatography-mass spectrometry (GC/MS),and the composition characteristics of molecular markers were compared and analyzed.The result shows that the four column chromatographic methods have a slight effect on the compositions of phenanthrenes,dibenzothiophenes,triarmatic-steranes markers in the aromatic hydrocarbon fraction,but the influence is severe in the occurrence of the naphthalenes.
