CO2 Dissociation using the Versatile Atmospheric Dielectric Barrier Discharge Experiment (VADER)
… (DBD) is a pulsed, low temperature, non-thermal, atmospheric pressure plasma which creates high energy electrons suitable for dissociating CO2 into its components (CO and O) as one step in the CCU process. Here I discuss the viability of using a DBD for CO2 dissociation on an industrial scale as …
