The influence of electric circuit parameters on NOx generation by transient spark discharge _ data

<p>dataset for</p> <p>The influence of electric circuit parameters on NOx generationby transient spark discharge</p> <p>&nbsp;</p> <p>Abstract</p> <p>Nitrogen fixation, production of NO and NO₂ from N₂ and O₂ in air, has been investigated with<br> transient spark self-pulsing DC discharges. NO production is boosted by the addition of capacitors<br> and an inductor to the electrical circuit which drives the discharge. The quantity of NO produced<br> per joule of electrical input energy is doubled, though the quantity of NO₂ produced drops. The<br> yield of NO is also increased because the modified circuit enables higher discharge currents to be<br> used. NO concentrations as high as 2000 ppm were obtained with input energy densities of around<br> 300 J per litre of input gas, whilst NO₂ concentrations were around 150 ppm. This simple<br> modification of the driving circuit may have potential for optimizing the plasma chemistry with<br> other input gas mixtures and for scaling up nitrogen fixation from air.</p>
