摘要：

The behaviour of organic carbon, organic chlorine, and the volatile organic chlorine in fly ash was studied during thermal treatment at 275-degrees, 300-degrees, 350-degrees-C. Additionally the formation of PCDD/PCDF, PClBz and PClPh was investigated. It is shown that the degradation of carbon can be described by a combination of two first order reactions. These reactions and the change of the organic chlorine are correlated with the de-novo-synthesis of organic chlorocompounds. The yields of the reaction giving PCDD/PCDF PCBz and PClPh were determined. In addition differential scanning calorimetry is used to describe the change of reactivity of the fly ash during the thermal treatment.
