Development of a gliding arc plasma reactor for CO2destruction

Abstract: A gliding arc plasma reactor was designed to destruct carbon dioxide (CO 2 ), which is a major greenhouse gas. To increase the CO 2 destruction rate with a high processing gas volume, an orifice baffle for gathering the gas flow at the centre of the electrodes was installed in the gliding arc plasma reactor. The CO 2 inflows with methane (CH 4 ) and steam (H 2 O) improve the CO 2 destruction. The parametric studies have been made of the change of CH 4 addition, gas injection velocity of the centre nozzle, chan… Show more

“…Interestingly, it can be deduced from Figure 6 that the MW plasma in vortex configuration yields a very similar conversion in the entire range of gas flow rate investigated, i.e., from 15 SLM to 30 SLM. This is quite remarkable, because a drop in conversion upon increasing flow rate is usually observed at constant power in most plasma experiments [5,7,13,15], although the non-linear influence of flow rate on the CO 2 conversion was also reported for MW plasmas in CO 2 +H 2 gas mixtures [32], a CO 2 RF discharge [45] and gliding arc plasmatron reactors [8,9]. This effect might be attributed to the complex interplay between the vortex gas pattern, the non-uniform absorption of MW power and the chemistry of CO 2 decomposition.…”

“…The global need for efficient CO 2 utilization technologies recently highlighted new ideas for re-use and conversion of CO 2 waste streams into added-value products [1][2][3][4][5]. Multiple papers demonstrated the potential of different plasma systems for activation and dissociation of this highly inert gas [6][7][8][9][10][11][12][13][14][15][16]. In general, microwave (MW) discharges are considered to be one of the most promising plasma systems for CO 2 decomposition due to their capability to utilize the highly efficient vibrational excitation kinetics of the non-equilibrium discharge [10,[17][18][19].…”

“…GA reactors have shown promising performance in CO2 conversion, with energy efficiency around 25-30%, but conversion limited to 8-9% [14][15][16], due to the limited fraction of gas passing through the arc. Moreover, they suffer from problematic electrode degradation, and significant convective heat losses [17].…”

“…This RVF surrounded by the FVF stabilizes the arc plasma in the center. This novel design results in a better thermal insulation, which reduces heat loss and prolongs the lifetime of the electrodes. , A diagram of the entire experimental system including a photo is shown in Figure S.1.…”
