One of the actual major societal challenges is the reduction of the CO2 emission. This can be achieved either by controlling the production of this greenhouse gas, or by converting the ejected CO2 into other molecule(s) which then can used in other industrial processes, or by the sequestration of the gas.
In this fundamental study, pure CO2 is transformed in an Inductively Coupled RF plasma at low pressure, under different experimental conditions (pressure, flow, power, pulsing…), in order to optimize its conversion into CO. The challenge of this approach consists into quantifying in situ the reaction yield. We show that by calibrating a quadrupole mass spectrometer with reference gases, it is possible to reach this goal. We present CO2 -> CO conversion rate reaching up to 70%, for different plasma and pressure conditions, with a reactor energy efficiency up to 2%.
The measurements were compared with the results from a 2D plasma simulation based on the drift and diffusion approximation.
