Physicochemical Investigation of Homogeneous Pulsed Discharge in N₂/O₂for Ozone Production

Dynamic Characteristics of Positive Pulsed Dielectric Barrier Discharge for Ozone Generation in Air

“…The electron density reaches a peak of 3.58×10 18 m −3 when ionization is maximal and then decreases dramatically as a result of recombination and attachment processes. The major positive ion is O + 2 in the discharge, and its density is higher than N + 2 density because the ionization of oxygen molecule is less than that of nitrogen molecule as reported by Benyamina et al [28] . O + 2 density reaches a peak of 2.46×10 18 m −3 at 4.5×10 −7 s, and then reduces to one third because of the recombination and attachment processes as well as charge transfer reactions such as R24 and R55.…”

Methane conversion using a dielectric barrier discharge reactor at atmospheric pressure for hydrogen production

“…Hydrogen and other hydrocarbons can be produced by converting methane or carbon dioxide/methane mixtures by using plasma reforming [2][3][4], from biomass gasification [5][6][7], and from water by electrolysis [8] and it can be used to feed fuel cells and internal combustion engines to generate electrical and/or mechanical energy [9]. Dielectric barrier discharge (DBD) at atmospheric pressure possesses several applications such as ultraviolet generation [10], ozone production [11], and conversion of natural gas and hydrocarbons into synthesis gas (syngas). In our work, DBD is used to convert CH 4 into hydrogen and other hydrocarbon species.…”
