Abstract :
In this work, keeping in mind that we recycle in CO/sub 2/, replacing H/sub 2/ of the energy circulation system with CH/sub 4/, and we tried to clarify the properties of decomposition of CH/sub 4/, CO/sub 2/ by barrier discharge. In case that the decomposition of CH/sub 4/ was carried out, CH/sub 2/, CH/sub 3/ and CH/sub 4/ decreased. And H/sub 2/, C/sub 2/H/sub 2/, C/sub 2/H/sub 4/ and C/sub 2/H/sub 6/ increased as a function of time. The increase of H/sub 2/, C/sub 2/,H/sub 2/, C/sub 2/H/sub 4/ and C/sub 2/H/sub 6/ showed the linear relation with increasing the potential of power supply. The rate of increase became larger with shortening electrode gap range from 2700V to 3500V in the potential of power supply. In the case that the decomposition of CO/sub 2/ was carried out, CO and O/sub 2/ increased after barrier discharge. The rate of increase for O/sub 2/ shows convex curve that had the maximum value at about 3800V.
