Résumé :

Plasma technology is very modular and can operate in moderate conditions. Additionally, it activates gas molecules by high energy electrons instead of heat, and it can convert intermittent renewable electricity into value added chemicals. Last but not least, the possibility of integrating plasma with a catalyst in “plasma catalysis” enables the selective production of desired products and can lead to improvements in the process efficiency. Therefore, in the past few years, plasma technology has started to be considered as a green alternative for fossil-based gas conversion processes. However, the industrialization of this process faces several challenges, such as the need for better insight in plasma-catalyst interactions, high energy consumption, as well as challenges for the development of industrial scale efficient reactors. In the framework of this thesis, we have tried to add to the state-of-the-art in plasma-based nitrogen fixation, by dealing with these three challenges, using a combined experimental and modelling work.
