Developments in CO2 dissociation using non-equilibrium microwave plasma activation for solar fuels

Vortex stabilized microwave plasma conversion of CO2 is considered as promising route for energy efficient dissociation towards CO production. Energy and conversion efficiencies are investigated in scans of reactor pressure, gas flow rate and specific power. Deterioration of efficiencies from 39% to 25% are observed at forward vortex plasmas at increasing pressures which is mitigated in reverse vortex configuration.
