To reduce PCDDs/Fs in the flue gas of incinerators, a kind of catalytic oxidation process has recently been recognized as one of the most effective decomposition methods. In this study, the decomposition behavior of Co-PCBs is investigated by comparing PCDDs/Fs in flue gas and using substitutive materials under dry/humid atmosphere. The decomposition mechanism of Co-PCBs is also investigated with the substitute. It is concluded that 1) Co-PCBs can be decomposed the same as PCDDs/Fs with the catalytic oxidation process even under the humid atomosphere of flue gas, 2) bi-phenyl (BP) is more suitable for the substitutes of Co-PCBs than Chlorobenzenes among no oxygen aromatic model-compounds and 3) the main reaction in the decomposition scheme of BP can be estimated to be on irreversible complete destruction of the aromatic nucleus.
