Abstract

The process of decomposition of organochlorine compounds by a three-phase ac plasma torch with vortex arc stabilization is studied. The plasma torch had two zones for introducing the plasma-forming media: the near-electrode and arc-burning zones. The near-electrode zone was fed with a shielding gas, and the arc-burning was fed with water vapor, methane, and vapors of organochlorine compounds. The resulting products were analyzed using mass spectrometry, XRD, scanning electron microscopy, and IR spectroscopy. In an experiment with chlorobenzene and carbon tetrachloride, in the gaseous and liquid fractions, only one chlorine-containing compound, HCl, was detected. However, in the experiment with chlorobenzene, the soot yield was 0.98 wt % of the raw material and the chlorine content in the soot was 1.61%. IR spectral data confirm the presence of the Cl–O and Cl–С bonds.

AC等离子体炬分解含氯烃过程中的烟尘形成

摘要

研究了三相交流等离子体炬稳定涡旋分解有机氯化合物的过程。等离子炬有两个用于引入等离子形成介质的区域：近电极区域和电弧燃烧区域。在近电极区域注入保护气体，在电弧燃烧中注入水蒸气，甲烷和有机氯化合物蒸气。使用质谱，XRD，扫描电子显微镜和IR光谱分析所得产物。在使用氯苯和四氯化碳的实验中，在气态和液态馏分中，仅检测到一种含氯化合物HCl。然而，在用氯苯的实验中，烟灰收率为原料的0.98wt％，烟灰中的氯含量为1.61％。
