以煤的索氏抽出物中正己烷流出物为样品,考察了煤化程度不同的两种煤样中的正构烷烃、类异戊二烯烃、芳烃、萜烷和甾烷等生物标志化合物的存在及其分布,讨论了这些生物标志化合物的相对比值与煤的古代埋藏环境和煤化过程的关系,结论与常用煤化学方法一致,也与作者以前对这两个煤样中的卟啉用有机地球化学法的结果相符合。 Using the n-hexane effluent of Soxhlet extract of coal as sample, the existence of biomarkers such as n-alkanes, isoprenoids, aromatics, terpanes and steranes was investigated in two coal samples with different degree of coalification And their distribution, discussed the relationship between the relative ratio of these biomarker compounds and the ancient coal burial environment and coalification process, the conclusion consistent with the common coal chemistry method, also with the author of these two coal samples in the porphyrin with organic earth The results of the chemical method are consistent.
