主　　题：polycyclic aromatic hydrocarbon coking single coal blended coal 

摘      要：The generation of polycyclic aromatic hydrocarbons （PAHs） during coking was studied and the contents of sixteen PAHs were measured by the devices of ultrasonic abstraction and high performance liquid chromatography for single coal coking and blended coal coking. The results indicated that the amount of generated PAHs during the first 1--4 h of coking is the most. Among these PAHs, the tetranuclear PAHs have a major portion and the Benzo[a]pyrene which can cause cancer, and teratogenesis and mutation is generated for a larger concentration more than emission standard value. Two PAHs are the main pollutants of PAHs pollution.
