One of the direct ways to achieve CO 2 conversion is through the use of a non-isothermal plasma environment. In this work, we present an experimental study of the dissociation of CO 2 in a magnetically-stabilized arc discharge in a cross-flow configuration, where the CO 2 gas flow is perpendicular to both the arc and the external magnetic field. The system works at atmospheric pressure. The study examines the effect of the gas flow and discharge current on the quantities of most interest, namely, the CO 2 conversion percentage and the energy efficiency of the process. The experimental results show that the conversion tends to increase with the current, while it drops as the gas flow rate is increased. The efficiency seems to decrease with the conversion percentage, as it increases with the flow rate.
