  Plasma processes are an innovative approach for the decomposition of CO2 in O
radicals and CO as a valuable carbon source. In this experimental work, a
tubular dielectric barrier discharge operating at atmospheric pressure has been
used to split CO2 and study its conversion considering the influence of
frequency and power, as well as the influence of various electrical regimes
(AC, AC pulsed regimes). The CO2 conversion has been measured by mass
spectrometry and gas chromatography while gas and walls temperatures have been
determined and correlated to evaluate their influence of the CO2 splitting.
