In this work, the dry reforming of methane was studied using a corona and glow discharge plasma microreactors. A chemical kinetic model was developed to understand the reaction better. The modelization allowed prediction of the reactants conversion according to the energy transfer to the gas (P×τ). The β value is trait of the energy cost, whatever this value was leeser indicated better efficiency. The β value of CH4 equal to 10.42 and 9.91 J and for CO2 equal to 12.24 and 15.42 J for corona and glow discharge plasma respectively, because the dissociation energy of CO2 higher than CH4. The kinetic model demonstrated that there is an exponential function between the conversion of CH4 and CO2 and plasma energy. Also, corona discharge plasma reactor with smaller CH4/CO2 ratio has higher energy efficiency for CO2 and lower for CH4.
