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.
