Description:
Chlorophenols have been studied as precursors to PCDD/F formation but generally these experiments have been carried out with unrepresentative concentrations and potentially overlapping formation mechanisms. Research has demonstrated that the kinetics of PCDD formation from chlorophenol over fly ash is strongly dependent on the chlorophenol precursor concentration. This study focuses on combustion conditions characteristic of MWI flue gases, such as very low levels of precursors and the presence of water vapor. By changing reaction conditions of temperature and gas phase precursor concentration this work attempts to establish the relationship between specific chlorophenols and the resultant PCDD/F congener products.
