Abstract— This work aims to get inside the plasma treatment of VOCs mixtures. At this purpose ethanol/acetone blends in air fed Dielectric Barrier Discharges have been studied. The two pollutants plasma removal does not seem to be affected by their coexistence into the discharge. Experimental investigations in dry and humid air DBDs show that water vapor content does not significantly improve the VOCs abatement; instead exceeding feeding gas humidity inhibits the two target molecules conversion. The ethanol/acetone mixtures exhausts showed the same chemical composition of each plasma treated compound singularly considered. The feeding gas humidity does not affect the by-products nature, but it seems to promote the complete oxidation chemical paths.
