抄録	The rise of atmosphere temperature by the “greenhouse effect” effect is thought to result from the increase of CO₂ gas, NOx gas, etc. Therefore, the decomposition treatment of CO₂ gas is an important research subject in order to solve global environmental problems. In this study, gas tunnel type plasma jet, which is a high energy plasma process, was used to decompose CO₂ gas, and the decomposition mechanism was clarified by varying the plasma operation conditions. In addition, the possibility of recycling systems of CO₂ gas is also discussed. Firstly, the performance test of the gas tunnel type plasma jet used for decomposition of CO₂ was conducted and the efficiency of CO₂ decomposition by using the high-energetic plasma jet was determined under various conditions. Secondly, the improvement of operating conditions of the plasma to enhance its performance was discussed. The decomposition ratio of CO₂ was about 30%, with a power of 8kW, and a CO₂ content of 10% in argon. Then the possibility for the gas tunnel type plasma jet to be a high efficiency CO₂ decomposition process was discussed.
