使用放电进行甲烷转化的研究已经很多年了。最近，许多研究小组开发了一种高频脉冲等离子体反应，用于将甲烷转化为高级碳氢化合物和合成气。将甲烷转化为合成气作为温室气体CO2和CH4（占人造温室气体的大部分）的利用方法也引起了相当大的兴趣。在这项研究中，使用圆柱形介质阻挡放电（DBD）反应器研究了脉冲电源的脉冲极性对甲烷和二氧化碳转化的影响。为此，对双极脉冲电源和单极脉冲电源两种电源进行了比较。输入电压和电源频率被用作操作变量。使用 DBD 进行甲烷 CO2 重整时，将双极脉冲电源的能量效率与单极脉冲电源的能量效率进行了比较。增加电压并...
Methane conversion using an electric discharge has been studied for many years. Recently, many research groups have developed a high-frequency pulsed plasma reaction for methane conversion to higher hydrocarbons and synthesis gas. The CO2 reformation of methane to synthesis gas has also attracted considerable interest as a method of utilization of the greenhouse gases, CO2 and CH4, which occupy most of man-made greenhouse gases. In this study, the influence of pulse polarity of the pulse power supply on methane and carbon dioxide conversions has been investigated using a cylindrical-type dielectric barrier discharge (DBD) reactor. For this purpose, two kinds of power supply were compared, that is, a bipolar pulse power supply and a unipolar pulse power supply. The input voltage and the power frequency were used as operating variables. The energy efficiency of the bipolar pulse power was compared with that of the unipolar pulse power for the CO2 reformation of methane using DBD. Increasing the voltage and ...
