| Removal of Hexanal by a Combination of Non-thermal Plasma and Natural Mordnite |
|
| 摘要: 本文研究了在低温等离子体和天然丝光沸石(Natural Mordenite，NMOR)的共同作用下对低浓度正己醛的降解性能。研究结果表明，在降解低浓度正己醛的反应中，低温等离子体与天然丝光沸石之间能产生很好的催化协同作用，当放电功率为2.8 W时，反应温度为80 ℃时，干燥空气气氛下，天然丝光沸石对1 200 mL·m-3正己醛的去除率为93.9%；另外天然丝光沸石经酸处理后，这种协同作用可以进一步提高，正己醛的去除率达到96.5%；天然沸石的结构性能稳定，在实验条件下，天然沸石连续使用55 h，催化活性未见下降。 |

| Abstract: The removal of hexanal was studied using a combination of non-thermal plasma and catalyst. The results showed that there was a synergistic function between the plasma and natural mordenite (NMOR) with a hexanal removal efficiency of 93.9% at 80 ℃ and 2.8 W discharge power. The removal efficiency can be further improved to 96.5% when natural mordenite was treated using 6 mol·L-1 HCl for 6 h. Natural mordenite was stable and the removal efficiency did not declined with a continuous use of 55 h. |
