Abstract
The paper proposes a scheme for controlling the formation of polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) during incineration using sorbent materials to remove the source of chlorine at high temperature. Results of previous experiments investigating the formation of PCDD/PCDF through low temperature (300 C), fly-ash-catalyzed reactions are demonstrated to have occurred through intermediate formation of gas-phase C12 by decomposition of the added catalyst CuC12. The dependence of PCDD/PCDF formation rates on C12 concentration is shown and the implications of the Deacon process on these rates is discussed.
