Effect of silica packing on ozone synthesis from oxygen-nitrogen mixtures

The effect of silica packing in an ozone generator fed with oxygen-nitrogen mixtures has been studied. The measurements were carried out in an ozone generator with a double-sided cooled discharge gap, in which silica packing has been placed. In the presence of the packing considerably higher ozone concentrations were achieved than in the ozone generator without packing. An especially clear effect of silica packing was observed in air-fed conditions. It has been found that the increase in the concentration of the obtained ozone coincides with the increase of N2O in the post-reaction gas.
