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.
