Abstract

Decomposition of chlorinated hydrocarbons, CCl4 and CHCl3, in gliding plasma was examined. The effects of initial concentrations, total gas flow rates, and power consumption have been investigated. The conversion result was relatively high. It reached 80% for CCl4 and 97% for CHCl3. Using atmospheric air as the carrier gas, the plasma reaction occurred at exothermic reaction and the main products were CO2, CO, and Cl2. Transformation into CCl4 was also detected for CHCl3 decomposition reaction. The conversion of CCl4 and CHCl3 were increased with the increasing applied frequency and decreasing total gas flow rate.

摘要

研究了滑行等离子体中氯代烃（CCl4 和 CHCl3）的分解。考察了初始浓度、总气体流速和功耗的影响。转化率相对较高，CCl4 达到 80%，CHCl3 达到 97%。使用大气空气作为载气，等离子体反应为放热反应，主要产物为 CO2、CO 和 Cl2。还检测到 CHCl3 分解反应转化为 CCl4。随着施加频率的增加和总气体流速的降低，CCl4 和 CHCl3 的转化率增加。
