The experimental results show that the distributions of content and toxicity equivalent quantity of PAHs in raw coal are similar to coal gasification but this compositions and contents are different. The rise of coal rank leads to the decrease of the content and TEQ of PAHs in raw coal and the increase of TEQ during coal gasification, while the content of PAHs emission from coal gasification increases first and then decreases with the increase of coal rank. The total PAHs contents generated in coal gasification of some sorts of coals are higher than in raw coal. The types of PAHs formed in coal gasification include undecomposed PAHs in raw coal, pyrosysthensis PAHs, and radical polymerization PAHs at high temperature.

试验结果表明：煤气化前后多环芳烃质量分数和毒性当量质量分数的分布特徵相似，但多环芳烃的组成和质量分数不同；煤化程度增加，原煤多环芳烃质量分数和毒性当量质量分数减小，煤气化多环芳烃质量分数先增后减，毒性当量质量分数与煤化程度呈线性关系；部分煤种气化多环芳烃的质量分数高於原煤多环芳烃质量分数，且煤气化多环芳烃的种类分为原煤未分解的多环芳烃、热解合成的多环芳烃、自由基高温缩合生成的多环芳烃。
