INVESTIGATION OF COX REDUCTION SYSTEM PROTOTYPE AT 1000CC VEHICLE REMOVAL GASES USING KNIFE-TO-PLATE GLOW DISCHARGE PLASMA

Abstract

COx reduction of exhaust gases from 1000cc vehicle has investigated using prototype reactor of corona glow discharge of plasma. Knife-to-plate electrodes configuration is used inside the reactor with DC high voltage source to generate corona glow discharges plasma. In this experiment, we investigate voltage-current parameter in conducting effective corona plasma development. COx reduction is done under two-corona condition for four-time duration exhaust gases hold in plasma condition. Results shows that biggest Decomposition Efficiency value of CO and CO2 are happens along with longer exhaust gases hold in plasma condition, with the best result for CO is 83,07% and for CO2 is 65,81%. This experiment also investigate knife electrode rotation influences in COx reduction efficiency with result that lower rotation velocity gives more sophisticated Decomposition Efficiency rather than the higher one. The best Decomposition Efficiency for knife electrode rotation for CO is 68,07% and for CO2 is 63,26%. Reduction crust that is found and investigate using anion-cation and FTIR analysis in this experiment shows the presence of NH4 + cation and CO3 2- anion that give a hypothesis that one of the compound formation from reduction crust is ammonium carbonate. A hypothetical chemical reaction process is presented to investigate how it formation build distribusi.
