Non-equilibrium plasma under atmospheric pressure takes place easily when microwave power is irradiated to porous carbon. The present study aimed to apply this phenomenon into environmental energy processes such as tar decomposition, and the fundamental examination was performed.It was resulted in that 1) decomposition of benzene as a modeled tar achieved to the conversion over 75 % in microwave power 400 W, 2) byproduct of carbon nano-tube yielded by introduction of ferrocene as a catalyst and the size was estimated as a level of 1.1 nm from Raman spectroscopic analysis, 3) plasma temperature was 7,600 to 8,000 K from emission spectra, and 4) observation by high speed video revealed a dynamic behavior of plasma generated with increase in microwave power, whose phenomena contributes to enhancement of reaction activity.
