摘　　要：采用甲烷为主要原料,在常温和常压条件下,利用滑动弧等离子体放电技术,进行了甲烷与空气、水蒸气重整反应的试验。试验研究了过量空气系数、反应气流量和水蒸气含量等参数对甲烷与空气、水蒸气重整反应的影响,并对重整副产物进行了分析。试验表明,当过量空气系数为0.8时,氢气选择性最高可达到45.9%;反应气流量达到14L/min时,单位氢气生产成本最低;在反应气中加入一定量的水蒸气,有利于重整反应的进行。In this study, the reforming of methane into hydrogen with oxygen and water vapor assisted by gliding arc discharge plasma was investigated at room temperature and atmospheric pressure. The effects of excess air coefficient, gas flow rate and water vapor content were considered, and the by-products were also discussed. In the experiment, the se- lectivity of hydrogen can be achieved up to the maximum of 45.9 % when excess air coefficient reaches about 0.8. The cost of producing hydrogen reaches the lowest point at 14L/min of gas flow rate. The injection of some water vapor could be better for the reforming reaction.
