摘要

STUDY ON THE EFFICIENCY OF CARBON TETRACHLORIDE DECOMPOSITION IN ARGON THERMAL PLASMA AND CHARACTERIZATION OF THE FORMED PRODUCTS. Decomposition of carbon tetrachloride in a DC thermal plasma reactor was investigated in argon atmosphere. The operational parameters such as plasma torch power and argon flow rate versus CCl4 conversion were examined. The CCl4 net degradation wits determined by GC-FID, the chlorine produced was quantified by iodometric titration, the solid carbon was characterised by Raman spectroscopy and by BET analysis. The solid carbon collected inside de plasma reactor was submitted to solid/liquid extraction and the desorbed species were identified by GC-MS.
