| 제목 | Product distribution of methane conversion reaction with various oxygen-containing gas using atmospheric dielectric barrier discharge |
| 초록 | This study examined the conversion of methane to synthesis gas and other higher hydrocarbons using dielectric barrier discharge with AC pulse power. Two metal electrodes of a coaxial-type plasma reactor was separated by a gas gap and an alumina. The inner electrode was located inside the alumina tube. The alumina tube was located in the stainless steel tube, which was used as an outer electrode. Effect of feed gas composition (methane, oxygen, argon, water and helium), flow rate, applied frequency, input voltage on methane conversion and product distribution were studied. The major products of plasma chemical reactions were ethylene, ethane, methanol, formaldehyde, formic acid, acetic acid, hydrogen, carbon monoxide and carbon dioxide. Increasing applied voltage and using background inert gas (helium and argon) enhanced the selectivity of hydrocarbons and methane conversion. The addition of water in the feed stream enhanced the conversion of methane and selectivity of hydrogen. |
