笔者以黄县褐煤为例,采用GC/MS技术研究其多环芳香烃组成,主要在两环至五环范围内检测出11类56个芳香烃化合物,其中芳构化萜烷类化合物占总组成的94％,它们大多与生物先质有密切的亲缘关系。本文样品取自山东黄县煤田北皂矿井下第三系黄县组,R_0=0.46％,其显微组分以腐植组为主占91.6％,其中密屑体68％;细屑体10.4％;壳质组和惰性组合量较低,分别为5.8％和2.5％。
Taking Huangxian lignite as an example, the author studied the composition of polycyclic aromatic hydrocarbons by GC / MS, mainly including 11 types of 56 aromatic hydrocarbons in the range of 2 rings to 5 rings. Among them, aromatics terpenoids accounted for 94% of the composition, most of them are closely related with biological precursors. The sample was taken from the Huangxian Formation of the Third Member of Beizao Coal Mine in Huangxian Coalfield, Shandong Province, with R_0 = 0.46%. The major component of the micro-component was 91.6% in the humus group, including 68% of dense crust, 10.4% While the combination of chitin and inertia was lower at 5.8% and 2.5% respectively.
