【摘要】 利用旋转电极的螺旋机构及时切换放电通道、降低通道内的热量和电子密度,阻止热不稳定性的发展,实现了均匀的大气辉光放电等离子体。依据等离子体作用下CH4-H2反应的产物分析和发射光谱检测结果,探讨和推测了常压辉光等离子体条件下CH4-H2转化的反应机理。更多还原

【Abstract】 A uniform atmospheric glow discharge mode was performed by using rotating electrodes with spiral geometries that could promptly switch off discharge passages and therefore reduce the heat accumulation and lower the electron density in discharge passages to stop the thermal instability.Based on the detection of these excited species and the analysis of products by gas chromatograph,the reaction mechanism of the conversion CH4-H2 to C2 hydrocarbons in the proposed process was studied.更多还原
