Kinetic Mechanisms in CO<sub>2</sub>-N<sub>2</sub> Plasmas

Abstract

In this work we undertake a joint modelling and experimental investigation to study the impact of N2 on the overall CO2 plasma conversion. We perform our simulations solving a Boltzmann-chemistry 0D self-consistent kinetic model with the LoKI (LisbOn Kinetics) tool [1] and we compare our results with experimental data measured in low-pressure DC glow discharges.

The admixture of N2 has a beneficial impact on CO2 decomposition [2]. Several reasons can be assigned to it and will be discussed at the conference. Understanding the impact of the different processes on the overall kinetics, along with the validation against experimental data, will contribute to further develop the existing models [2,3] and to better control and enhance CO2 conversion.
