specific properties of plasma reactors for a direct electron energytransfert 

• direct energy transfert from electron to carbon dioxide orbitals  that mean direct excitation states  

• excitation states depend of the equilibrium or non equilibrium factors such as the pressure,chock wave,hydrodynamic flow mixing... 

• main advantages:short residence time and very short starting reactor time which are in agreement with discontinuous processes
