摘要

实验考察了表面诱导等离子体化学处理(SPCP)对氯氟烃、丙酮、三氯乙烯和异丙醇的分解性能。当停留时间为1 s左右，反应器输入功率为10 W左右时，去除率可达90%或99%以上。丙酮是最稳定的物质，醇是最易分解的物质。采用气相色谱-质谱联用系统进行分解产物分析。酒精的分解产生丙酮，这是SPCD的不良副产物。从实验中计算出在空气中稀释的每一摩尔气体分解所需要的能量。丙酮和三氯乙烯所需的能量大约是氯氟烃的十分之一或二十分之一。

Decomposition of gaseous organic contaminants by surface discharge induced plasma chemical processing-SPCP

The decomposition performance of surface induced plasma chemical processing (SPCP) for chlorofluorocarbon, acetone, trichloroethylene, and isopropyl alcohol was experimentally examined. More than 90 or 99% removal rate was realized when the residence time was about 1 s and the input electric power for a 16 cm/sup 3/ reactor was about 10 W. Acetone was the most stable material and alcohol was most easily decomposed. A gas-chromatograph-mass-spectrograph system was used for decomposition-product analysis. The decomposition of alcohol produced acetone as an undesirable byproduct of SPCD. The energy necessary to decompose one mole of each gas diluted in air was calculated from the experiments. The necessary energy for acetone and trichloroethylene was about one-tenth or one-twentieth of that for chlorofluorocarbon.<>
