The fossil fuels consumptions and environmental restrictions have given a privileged place to renewable energies. Plasma-assisted production of fuel by dissociation of CO2 seems to be a promising approach for reducing greenhouse gas emissions firstly and secondly for the storage of the renewable energy produced from CO2 into hydrocarbons. However, the mechanism through which plasma-assisted dissociation of CO2 occurs is poorly understood due to non-linearity and complex nature of the problem which leads to a low efficient process. In this work, it is aimed to control the plasma-assisted dissociation of CO2 in order to increase the energy efficiency and the economic viability of the process.

A numerical model will be investigated from zero dimension to 2 dimension. The computational work will consider all complexities of the problem such as the local plasma chemistries and the spatial phenomena. Involving many chemical reactions in plasma-assisted dissociation of CO2, prohibitive in CPU time and memory storage, chemical reduction technique developed for combustion processes within the Aero-Thermo-Mechanics department of the Université Libre de Bruxelles will be adapted for our process. The numerical physico-chemical model for non-equilibrium CO2 plasma will be validated using experimental data provided by the Dutch Institute for Fundamental Energy Research. The final model will give fundamental insights on the manner through which a high energy efficient conversion could be achieved.
