| 摘 要： | 选取中国各地的7个烟煤煤样经过索氏抽提、浓缩、纯化等步骤,对其中含有的17种多环芳烃进行了GC测定,研究烟煤中多环芳烃的分布特征.分析发现,干燥无灰基碳质量分数在75%~88%之间,多环芳烃总量最大点发生在80%~83%.随煤化程度提高,高环芳烃含量呈增加趋势,且烟煤中碳含量、挥发分含量、氧碳摩尔比、氢碳摩尔比等参数与17种多环芳烃的总量存在一定关系.

| Abstract: | Seven bituminous coals were pretreated through Sohxlet extraction,rotation concentration and column purification,and seventeen PAHs tested by GC to investigate the distribution characteristics of PAHs in bituminous coals.It was found that the maximum point of total PAHs occurs in 80%~83% of the region,with dry ash free carbon mass fraction of 75%～80%.With the increase of coalification degree,the content of PAHs with more rings increases.Also,carbon content,volatile content,O/C mole ratio,and H/C mole ratio have some relationships with PAHs concentration in bituminous coals. |
