AN EXPERIMENTAL AND NUMERICAL STUDY OF THE THERMAL-OXIDATION OF CARBON-TETRACHLORIDE

Thermal decomposition of CCl4 was investigated at a high temperature u nder oxygen-rich, isothermal conditions. The temperature ranges from 4 00 to 1000 degrees C under the conditions of reaction time 2 seconds a nd an equivalence ratio 0.5. According to those results, CCl4 can dest ruct 99.99 percent at a temperature of 900 degrees C. Products obtaine d from thermal oxidation are carbon dioxide, chlorine and carbon monox ide. Tetrachloroethylene is observed as an intermediate in the oxidati on process, being formed to an insignificant extent only between 600 d egrees C and 850 degrees C. No carbon-chlorine bonds are left at 900 d egrees C. A detailed mechanism describing oxidation of CCl4 is obtaine d and comparisons with experimental results are made. Moreover, sensit ivity analysis is performed to identify major reaction equations by co mbining with a rate of production analysis for key species observed ex perimentally.
