摘要
利用GC-MS(色谱-质谱)对采自华北部分矿区煤样的氯仿抽提液中多环芳烃(PAHs)进行了比较分析。结果表明,煤中PAHs含量与镜质组含量呈负相关关系,与惰质组含量呈正相关关系;煤变质程度是影响煤中PAHs种类及其含量分布的主要外在因素。由于PAHs的大部分化合物,除三芳甾烃和部分菲系列之外都是在成煤过程中经过复杂的化学结构演化形成的,不同的环境造成不同芳烃化合物的生成,煤的沉积环境作为其化学成分的外在影响因素,对煤中PAHs种类及其含量分布的影响也是比较显著的。
The GC-MS was applied to do the comparison analysis on the polycyclic aromatic hydrocarbons （PAHs） from the chloroform extraction liquid of the coal samples in the Mining Area of North China. The results showed that there would be a negative relationship be- tween the PAHs content and the vitrainite content in the coal, and there would be a positive relationship between the PAHs content and the inertrinite content. The degree of coal metamorphism was the external major factor affected to the PAHs types and content distribution in the coal. Except three aromatic steroid hydrocarbon and some phenanthrene series, the major compounds of PAHs were formed after com- plicated mechanical structure evolution during the coal formation procedure. The different environment caused the production of the different aromatic compounds. The sedimentary environment of coal was as the external influence factor of the chemical components. The PAHs types and content distribution in coal was also obvious.
