摘要
本文研究云南宝秀盆地一个钻孔不同深度的泥炭和褐煤抽出物芳烃馏分中多环芳烃的组成。用GC和GC/MS鉴别了它们的组份,结果表明,从双环和三环单芳构化、双芳构化、三芳构化到四环双芳构化、三芳构化及四芳构化和五环单、双芳构化、三芳构化、四芳构化以及C环开裂的萜类化合物均有不同含量的存在,这说明在煤化过程早期芳构化就进行到相当的深度,也说明云南陆源高等植物,尤其是喜温树类的造煤物种为宝秀盆地提供了特殊的芳构化有机组成系列。
Polynuclear aromatic hydrocarbons in the extracts of peat and lignite which come from same column sample with different depths at Baoxiu basin were investigated by GC and GC/MS techniques.Compounds having up to five rings with different degree of aromalization as well as C-ring cleaved aromatics are all existing with various concentration in these samples. The occurence and distribution of these aromatics demostrate that the aromatization in early stage of the coalification of peat and lignite proceeds in considerable extent, but it is mainly in cata-condensed aromatics rather than in peri-condensed configuration. The genesis and the coalification of peat and lignite are disussed in detail.
