Effect of temperature and oxygen on the formation of PCDD/Fs surrogate

摘要

The correlation between chlorobenzenes (CBzs) and PCDD/Fs in the flue gas of a hospital waste incinerator, and effect of temperature and oxygen on the CBzs formation from fly ash were investigated through experiments. The results showed pentachlorobenzene and hexachlorobenzene are good indicators for PCDD/Fs. The optimum temperature of CBzs formation was in the range between 350°C – 450°C, and CBzs yield increased significantly when oxygen content was over 10%, which are very similar with the impact of such parameters on PCDD/Fs formation.
