    Distribution, Occurrence and Accumulation Factors of Chlorine in Coal from Jining Coal Field

    • 摘要: 氯是煤中普遍存在的一种元素, 氯的含量与分布影响着煤的加工与利用.通过对济宁煤田各主要可采煤层中氯含量的分析可知, 研究区属低氯煤层, 氯含量的高低及分布与煤层空间位置、成煤植物、沉积环境和地下水活动等因素有着重要的关系.同时, 对氯在煤中的赋存状态进行了研究, 通过氯与有机显微组分、灰产率等指标的相关性计算, 得出研究区煤中的氯与有机显微组分成正比, 与灰产率成反比, 说明氯主要存在于煤的有机质中, 并且主要是存在于镜质组分的微孔隙中.
