1,2-Dichloropropane 130 or 1150, 1-chloro-2-propanol 360, CCl4 400, C2Cl4 100,1,1,2,2-tetrachloroethane 850, and 2,4-dichlorophenol 160 or 400 mg/m(3) air, were studied in 0.1% Pt/ gamma-Al2O3 or 27.3%Cu-27.8%Zn catalyzed (contact time, 0.60 s) oxidations run at 200-600degreesC. Air and water (fed to evaporator) flow rates were 120-200 L/h and 32.5 g/h, resp. Flue gases and condensates were analyzed for adsorbed organic halogens (AOX) and for polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/F). At 375degreesC over Pt, 1,2-dichloropropane, CCl4 and 2,4-dichlorophenol were 100% oxidized; C2Cl4 and tetrachloroethane required 500degreesC. No 2,3,7,8-TCDD was detected, except for < < 0.1 ng TEQ/m(3) in the 2,4-dichlorophenol flue gases at 375degreesC. The overall toxicity of the flue gases was 2.9-10.9 pg TEQ/m(3) (where TEQ = Sigma[Q(i) x (toxic equivalency factor)(i)] and Q(i) = concentration of i-th dioxin). Organochlorines were thus shown to be catalytically 100% incinerable at temperatures much lower than those of high-temp. combustion (1200-1500degreesC).
