本文用与相色谱法鉴定了昆明盆地晚新生代沉积物中干酪根热解产物,干酪根的热解色谱表明,热解产物的主要成分为正烷烃、正烯烃、类异戌二烯烷烃、类异戌二烯烯烃和烷基苯等。Ⅰ型干酪根的热解产物主要是正烷烃、正烯烃,而在Ⅲ型干酪根热解产物中,烷基苯、姥鲛烯-1和姥鲛烯-2很丰富,通过研究不同类型干酪根的热解产物组成特征表明,热解-色谱法为研究沉积有机质的成熟度、有机质类型和沉积环境,提供了重要信息。
The pyrolysis products of kerogen in late Cenozoic sediments in Kunming Basin were identified by phase-contrast chromatography. Pyrolysis chromatogram of kerogen showed that the main components of the pyrolysis products were n-alkane, n-alkene, isoparaffin, Isohexadienoid alkene and alkyl benzene and so on. Type I kerogen pyrolysis products are mainly n-alkanes, n-olefins, and type kerogen pyrolysis products, alkyl benzene, promethien-1 and basal-2 is very rich, through the study of different types of kerogen The pyrolysis product composition characteristics indicate that pyrolysis chromatography provides important information for studying the maturity, organic matter type and sedimentary environment of sedimentary organic matter.
