不同煤种中可提取多环芳烃的分析

Analysis on PAHs Extracted From Different Rank of Raw Coal

煤利用过程中释放多环芳烃类污染物带来重大环境问题,研究不同变质程度煤中PAHs的含量与分布可为煤利用过程中的PAHs的形成与释放控制提供资料。本文在对淮北煤中PAHs的提取分析的基础上,结合本实验室研究数据,着重分析了不同煤种对可提取多环芳烃含量、分布影响。研究认为煤中碳、氢、氧及其它煤质组分与可提取多环芳烃有着密切的关系。

Polycyclic Aromatic Hydrocarbons（PAHs） can bring serious environmental problems due to coal using. On the content and distribution of PAHs in different rank of raw will provide the suitable references for people to understand the formation and emission of PAHs during coal utilization. Based on analyzing PAHs in coals from the Huaibei coalfield and data in our Lab., impact factors on the content and distribution of PAHs in raw coals are discussed in detail. The close relationship between PAHs extracted from coals, Carbon, Hydrogen, Oxygen and other coal quality are concluded.
