| Methane conversion using an electric discharge has been studied for many years. Recently, many research groups developed a high-frequency pulsed plasma reaction for methane conversion to higher hydrocarbons and synthesis gas. CO2 reforming of methane to synthesis gas has also attracted considerable interest as a method of utilization of greenhouse gases, CO2 and CH4, which occupied most of man-made greenhouse gases. In this study, the influence of pulse form of applied voltage on methane and carbon dioxide conversions and product selectivity has been investigated using a cylindrical type DBD reactor. For this purpose, three kinds of power supply were compared, that is, AC power supply which has high-frequency sinusoidal wave form, AC pulse power supply which has modified ac pulse wave form, and DC power supply which has high-frequency bipolar DC pulse form. The conversions of methane and carbon dioxide were enhanced using AC and DC pulsed plasma. The lower pulse width was more profitable economically. |
