| 摘 要： | 采用大气压等离子体射流,以CH4和CO2直接作为放电气体进行常压下重整制合成气的实验研究,考察了等离子体射流的放电特征及放电距离、放电功率、原料气配比和流量对反应的影响。结果表明,该等离子体具有放电稳定、均匀的特征。重整反应的主要产物为合成气,只有少量的H2O和积炭生成。优化的反应条件为放电距离为9 mm,CH4和CO2的摩尔比为4/6。当原料气流量为1 000 mL/min,放电功率为88.4 W时,CH4和CO2的最高转化率为分别为94.99%和87.23%。甲烷和二氧化碳的转化率随放电功率的增加而增加,随流量的增加而减少。

| Abstract: | An experimental investigation on CO2 reforming of CH4 to synthesis gas was performed by a novel atmospheric pressure plasma jet,which is initiated by an alternating current of 50 Hz and a high ratio transformer.The plasma jet proved to be a stable and uniform atmospheric pressure discharge that held the advantages of both thermal and non-thermal plasma.The effects of discharge distance,CH4/CO2 mol ratio in the feed,feed flow rate and discharge power on the reforming reaction were investigated.The results sh... |
