Abstract

Conversion of carbon dioxide (CO2) using gliding arc plasma was performed. The research was done to investigate the effect of variation of total gas flow rates and addition of auxiliary gases--N2, O2, air, water--to the CO2 conversion process. This system shows higher power efficiency than other nonthermal plasma methods. Experiment results indicate the conversion of CO2 reaches 18% at total gas flow rate of 0.8 L/min and produces CO and O2 as the main gaseous products. Among auxiliary gases, only N2 gives positive effect on CO2 conversion and the power efficiency at N2 concentration of 95% and total gas flow rate of 2 L/min increases about three times compared to pure CO2 process.

摘要

采用滑动弧等离子体对二氧化碳（CO₂）进行了转化。开展该研究是为了探究总气体流量变化以及向CO₂转化过程中添加辅助气体（N₂、O₂、空气、水）的影响。该系统显示出比其他非热等离子体方法更高的功率效率。实验结果表明，在总气体流量为0.8 L/min时，CO₂转化率达到18%，并产生CO和O₂作为主要气态产物。在辅助气体中，只有N₂对CO₂转化有积极影响，与纯CO₂过程相比，在N₂浓度为95%且总气体流量为2 L/min时，功率效率提高了约三倍。
