在平推流反应器中，采用介质阻挡放电对甲烷和二氧化碳的类沼气混合物进行了转化研究。一个13.56 MHz的电源产生的大气等离子体放电。研究的甲烷浓度范围为0至100%，缺失部分用二氧化碳填充。将该混合物用氦气稀释至2.5%，其中小部分产物流在100毫巴的总压力下通过由白池和四极质谱仪支持的傅里叶变换红外光谱仪在线监测。以不同的流速驱动反应器。该DBD反应器产生所有三种烃，其中乙烷是主要化合物。当等离子体区的功率从30 W增加到65 W时，乙烷的浓度增加。如果入口流中甲烷的分数增加，则该产物浓度也增加。当气流由2.5%甲烷和97.5%氦气组成，流速为200 sccm时，产生最高量的乙烷（5.4%）。(C)2012爱思唯尔有限公司保留所有权利。
The conversion of biogas like mixtures of methane and carbon dioxide was studied in a plug flow reactor with a dielectric barrier discharge. A 13.56 MHz power supply generated the atmospheric plasma discharge. Studied concentration of methane ranged from 0 to 100%, with missing part filled up with carbon dioxide. This mixture was diluted with helium to 2.5% with small part of the product stream monitored online at a total pressure of 100 mbar by a Fourier transform infrared spectrometer supported by a White-cell and a quadrupole mass spectrometer. The reactor was driven at different flow rates. This DBD reactor produces all three hydrocarbons, with ethane being the major compound. The concentration of ethane increases when the power in the plasma region increases from 30 to 65 W. This product concentration also grows up, if the fraction of methane in the inlet flow is increased. The highest amount of ethane (5.4%) is produced, when the gas stream consist of 2.5% Methane and 97.5% helium at a flow rate of 200 sccm. (C) 2012 Elsevier Ltd. All rights reserved.
