Experiment and Analysis on the Treatment of Gaseous Benzene Using Pulsed Corona Discharge Plasma 总被引:2,自引:0,他引:2
An experiment and analysis on removal of gaseous benzene by pulse corona inducedplasma is presented in this article. Important parameters effecting removal efficiency have been investigated, such as pulse peak voltage, pulse frequency, gas inlet concentration, gas flow rate and reactor temperature. The result shows that the removal efficiency increases with the increase in pulse peak voltage, pulse frequency and reactor temperature, but decreases in the rise of gas inlet concentration and gas flow rate. On the condition of Vp = 36 kV, f = 80 Hz, C = 1440 mg/m^3 and Q = 640 ml/min, the largest removal efficiency is 98%. Finally, the reacted products are qualitatively analysed and the reaction processes are deduced in combination with plasma-chemistry theory. 相似文献

为了优化调制烟叶中的化学成分,采用了低温常压Ar/O2等离子体处理方法结合近红外光谱分析,对烟草考察了不同放电时间的处理效果。结果显示:等离子体处理后,烟碱等主要的五种化学成分的含量随处理时间的增加均有改变。因此,需要对输入气体、放电电压、放电距离等更多的影响因素进行深入研究,达到提高烟叶品质的目的。 相似文献

提出了一种以酞菁锌(ZnPc)掺杂多壁碳纳米管(MWCNTs)作为声表面波(SAW)传感器的敏感材料用于室温下检测二氧化氮(NO2).通过超声振荡等方法将研磨的MWCNTs和ZnPc分散于N,N-二甲基中,然后运用微量移液器滴涂到SAW器件的敏感区.我们对ZnPc/MWCNTs薄膜用扫描式电子显微镜(SEM)进行了表面形态表征.实验结果表明,基于MWCNTs的ZnPc SAW器件能在常温下检测最低浓度为10-6的NO2.在3个月内对器件的灵敏度、稳定性、选择性也进行了评估. 相似文献
