In the recent decade, integrating the advantages of thermal and non-thermal plasma technology for CO2 splitting and CH4 pyrolysis has gained significant interest. CO2 dissociation in a newly developed swirl flow-induced rotating glow discharge and CH4 pyrolysis in a swirl induced point-plane arc discharge reactor configuration will be discussed in this seminar. A novel swirl injector was designed to produce forward vortex by eight guided vanes. The discharge and fluid dynamics studies revealed that the magnitude of tangential velocity and secondary vortex formation affects the rotational frequency of the discharge. It was also found that the anchoring point of the rotating glow discharge root is greatly influenced by the increased pressure gradient at turbulent regime. The conversion of CO2 as a function of flow rate was found to increase in the laminar regime, and decrease in the turbulent regime. With increasing specific energy input from 0.25 kJ L-1 to 3.4 kJ L-1, there was a rise in conversion from 1.9% to 6.7%, which indicates the high residence time and high energy deposition to lesser number of CO2 molecules. For methane pyrolysis, plasma column formed at the central hub of swirl electrode exhibit enhanced energy transfer to CH4 molecules due to formation of central recirculation zone. The effects of flowrate on high frequency high voltage discharges are investigated. The yield of the major product, H2 was 16%, and minor hydrocarbons like acetylene and ethane were also reported. The selectivity to hydrogen was high and highest methane conversion of 19.7% was achieved at flowrate of 0.5 LPM and input power of ~ 55 W. Finally, in terms of conversion, hydrogen yield and solid carbon purity, this reactor presents a promising approach for carbon neutral hydrogen production from methane.
