Study of ozone generation in an atmospheric dielectric barrier discharge reactor

A numerical study of species and electric field distributions in pulsed DBD in oxygen for ozone generation

“…The highest ozone yields of about 100 g/ kWh in dry air and 202 g/kWh in oxygen were achieved. Wu [5] studied experimentally and theoretically the impact of various parameters on ozone generation in N 2 /O 2 parallel-plate pulsed DBD with two alumina dielectric layers and obtained the highest ozone yield of 170 g/kWh. High ozone yields far more than that of commercial ozone generator were achieved in these studies, but their ozone concentrations were rather low, less than 20 g/Nm 3 .…”

Fundamental Properties and Applications of Dielectric Barrier Discharges in Plasma‐Catalytic Processes at Atmospheric Pressure

“…For example, the reactivity of the plasma may prevent catalyst deactivation or reduce catalyst poisoning. DBDs are widely used for ozone production [13,14], exhaust gas purification removing CO [15], NO x [16], SO 2 [17] or volatile organic compounds (VOCs) [18]. Depending on the given plasma-catalyst configuration, the longlived or/and the short-lived species generated in the plasma can contribute to chemical conversion.…”

Exploration of a MgO cathode for improving the intensity of pulsed discharge plasma at atmosphere

“…More electrons can be generated when the MgO cathode is applied, which induces more gas molecules to collide with the electrons and then leads to the production of electron avalanche. Afterwards, high-energy electrons, ions and free radicals are generated, and a lot of them are recombined to produce ozone, which can be produced by the following procedure [28,29]: Therefore, the production of ozone with and without the MgO cathode is investigated in the study. As shown in figure 10, with the increase of peak voltage, the concentration of ozone increases.…”
