In recent papers [1-2], we have shown results obtained by implementing a self-consistent
time-dependent kinetic model of a pure CO plasma applied to conditions generally met in
microwave, dielectric barrier and nanosecond repetitively pulsed discharges. The model is
based on the coupling between the Boltzmann equation for the electron energy distribution
function (eedf), the CO vibrational and electronic excited state kinetics and a simplified
global model for dissociation and ionization plasma chemistry. The results reported in [1-2]
have shown the importance of the model to understand the energy exchange processes
between the different vibrational and electronic modes of the plasma molecules and the free
electrons. In the present contribution, we will show results obtained by inserting the CO
kinetic model into the more complex model which describes the kinetics of a reacting CO2/
CO plasma mixture [3-8], focusing on the problem of CO2 activation by means of plasma
technology. Attention will be made in the description of the most important processes
linking the CO and CO2 kinetics and to the contribution of the CO and CO2 electronic
excited state kinetics in affecting the time-dependent eedf of the reacting mixture.
