大气压旋转螺旋状电极辉光放电等离子体催化甲烷偶联
摘要:
采用新研制的具有旋转螺旋状电极的大气压辉光放电等离子体反应器催化甲烷偶联制碳二烃. 实验采用铜电极和不锈钢电极分别考察了输入电场峰值电压和甲烷、氢气进料流量等参数对甲烷转化率和碳二烃收率、选择性的影响. 在长时间连续反应无明显积碳的情况下, 最佳试验结果是电极材料为金属铜, 进料流量为60 mL•min-1, V(CH4 )/V(H2)=1的条件下, 输入电场峰值电压为2.3 kV时, 甲烷转化率为70.64%, 碳二烃单程收率及其选择性分别为69.85%和 99.14%.

Methane Coupling in Atmospheric Pressure Glow Discharge Plasma with a Rotary Helix Electrode
Abstract:
Methane coupling to produce C2 hydrocarbons was studied with a newly developed rotary helix electrode in glow discharge plasma at atmospheric pressure. Effects of peak electric voltage and feed flow rates of methane and hydrogen on CH4 conversion, C2 yield, and the selectivity were investigated using copper or stainless steel electrode. 69.85% of C2 single process yield, 70.46% of CH4 conversion, and 99.14% of C2 selectivity were obtained at optimized conditions.
