Effect of Microwave on the Treatment of Gaseous Solid-state Low-cyclic PAHs in Coke Flue Gas

The polycyclic aromatic hydrocarbons（PAHs） were collected from absorbing media of activated carbon and silicon carbide by dichloromethane and glass fiber. Ultrasonic extraction and high performance liquid chromatography（HPLC） were used to qualitatively and quantitatively analyze the low cyclic polycyclic aromatic hydrocarbons,and the effects of microwave temperature,quality of silicon carbide,mass and particle size of activated carbon on the degradation of low rings polycyclic aromatic hydrocarbons were investigated. The experimental results show that activated carbon and silicon carbide have a certain effect on the treatment of polycyclic aromatic hydrocarbons（PAHs） as microwave absorbing media and microwave,and the treatment effect of polycyclic aromatic hydrocarbons is better than that of gaseous polycyclic aromatic hydrocarbons. Compared the two kinds of absorbing media,silicon carbide have the better treatment effect on the gaseous polycyclic aromatic hydrocarbons and solid state polycyclic aromatic hydrocarbons.
