The problems that arise from climate change can no longer be ignored by our society. They are gaining more and more attention in the media and various researchers are investigating techniques to limit climate change. The latter is caused by the increasing concentration of CO2 in our atmosphere.

It is therefore necessary to limit the emission of CO2 as much as possible. A technology that is extensively investigated for the conversion of CO2 into useful chemicals and fuels is plasma technology. In this thesis the CO2 conversion in a gliding arc plasmatron (GAP) is studied. This is a plasma reactor that uses a tangential gas inlet to obtain a vortex. This configuration has several advantages over a classical gliding arc reactor.

During this doctoral research, the influence of the reactor configuration and the addition of various other gases on the CO2 conversion and energy efficiency were studied. The plasma arc has also been visualized with a high-speed camera. The research shows that the GAP is very promising for CO2 conversion. The final chapter of this thesis presents the results of a techno-economic study and proposes possible points of improvement, which are necessary for potential industrialization of the GAP.
