To reduce DXNs (PCDDs/DFs and Co-PCBs) in the flue gas of incinerators, a catalytic oxidation process has come into wide use because of its high effectiveness and easy operability. In this study, catalytic decomposition characteristics of various aromatic compounds, for example PolyChlorinated Naphthalenes (PCNs) and Polycyclic Aromatic Hydrocarbons (PAHs) as well as Chlorophenols (CPs) and Chloro-benzenes (CBzs), have been investigated comparing with DXNs, using V-W/Ti catalyst reactor in the flue gas from the municipal solid waste incinerator plant. It is found that 1) PCNs and CPs can be decomposed with high efficiency such as DXNs, 2) decomposition rate of PAHs is a little lower than DXNs, 3) CBzs is rather hard to be decomposed and 4) the activity of the catalyst has been kept after 18000hrs of exposure time in stearm of the flue gas.
