1,2-Dichloropropane 130 or 1150, 1-chloro-2-propanol 360, 2,4-dichlorophenol 160, CCl4 400, C2Cl4 100, 1,1,2,2-tetrachloroethane 850, triethanolamine 180, diphenylsulfone 128 and thiazole 480 mg/m(3) air, were studied in 0.1%Pt/gamma-Al2O3 (KP-910) or 27.3%Cu-27.8%Zn (TMC 3/1), TMC 2 or vanadium catalyzed (contact time, 0.60 s) oxidations run at 200-600degreesC. Air and water vapor flow rates were 25-200 L/h and 15-32.5 g/h, resp. Flue gases were analyzed for CO, HCHO, SO2, and NO. and condensates for total org. C, HCHO, and Cl and SO4 ions. The final products were CO2, H2O, HCl and intermediates included Cl-2, HCHO, SOx, NOx, All the organochlorines were catalyticaily -100% oxidizable at 375degreesC or 500degreesC (chloroethanes) or 550degreesC (S compounds), i.e., at temps. much lower than those used in high-temp. combustion (1200-1500degreesC). Catalysts were fully active for 300-1500 h.
