It had been U.S. Environmental Protection Agency(EPA) suggested the 16 polycyclic aromatic hydrocarbons(PAHs) must take priority of control due to potential harm to people's health. The extensive amount of data show the part of PAHs source from the utilization of the coal. During the coal conversion process, PAHs released may be divided into two categories according to their formation pathways. One category is derived from complex chemical reactions and the other is free PAHs transferred from the original coals. The main idea of this study is to quantitatively analyze the total PAHs amount in the raw coal and get the relationship between PAHs and the coal properties. The results indicated that the amount of the PAHs of coal achieve to the maximum in the carbon content at 80.41%, the volatile yields at 37.19%, the O/C ratio as 0.1 and the H/C ratio as 0.8. The results also show that the rapid Soxh let extraction technique used in PAH extraction is more efficiency and environmentally friendly than the conventional Soxh let extraction technique.
