摘要：

 考察了在常温常压条件下利用滑动弧放电等离子体,使CH4与CO2重整制取合成气的效果,分析了供给电压、原料流速、预热温度等参数对转化率、选择性和制氢能耗的影响.结果表明,滑动弧放电可突破常温时热力学平衡的限制,有效促进重整反应的进行.与其他等离子方法相比,滑动弧放电的能量效率显著提高.增大电压或预热温度,可提高氢气选择性,促进氢气生成；增加流量,能量效率随之提高,但流量过大时,氢气选择性显著下降.当CH4与CO2的量比为1∶1、供给电压为8 640 V、喷嘴流速为130 m/s、预热温度为400 K时,制氢综合能耗最低,为103.1 kJ/L,此时单位氢气电耗为18.6 kJ/L,转化能力为6.37 mmol/kJ.
Abstract:

In ambient temperature and pressure, CO2 reforming of methane to produce synthesis gas by gliding arc discharge was investigated. The effects of supply voltage, total flow rate and preheating temperature on conversion, selectivity and hydrogen production energy cost were studied. The results show that gliding arc discharge can accelerate this reaction efficiently, even break through thermodynamic equilibrium restriction at ambient temperature. Compared to other plasma technologies, the energy efficiency of gliding arc discharge is obviously improved, and increases by enhancing flow rate. Hydrogen selectivity increases by enhancing supply voltage or preheating temperature. And when the total flow rate is large, the hydrogen selectivity will decrease significantly. When substance ratio of CH4 to CO2 is 1∶1, when the discharge voltage is 8 640 V, the flow rate through nozzle is 130 m/s, the preheating temperature is 400 K, then the total cost of this reaction is lowest with the value of 103.1 kJ/L, and the electrical cost is 18.6 kJ/L, the conversion ability is 6.37 mmol/kJ.
