Analysis of ozone generation process and micro-channel intensity distribution using Discharge Analysis Method

Cieplak T., Yamabe C., Olchowik J. M., Ozonek J.

The growing range of ozone application followed by the increase of its production makes the problem of ozone synthesis process optimization very significant from the viewpoint of unit energy consumption. Ozone, using silent discharge method, is mostly generated in the micro-discharge, however the other micro-channel also decomposes it. In order to take advantage of the whole discharge area the micro-discharges should be uniformly distributed as far as possible. A conventional energy sources uses as a fuel coal or oil. In some cases of an ozonizer use is not possible to reach power lines. From the other point of view, application of traditional power sources causes an environment pollution. To get the ozone generation process as clean as possible and also effective, in the presented research a plate ozonizer with PV modules was used.

Plasma-catalytic processing for environmental protection

Krawczyk K.

Polish Journal of Chemical Technology

2002

Vol. 4, nr 2

17-20

Plasma-catalytic processing may be an efficient way for the decomposition of tetrachloromethane and nitrous oxide. The silent and the gliding discharges combined with a catalytic bed have been applied. The gliding arc discharge combined with TiO" SiO2 (ąuartz glass), and y-Al,O, beds packing has been used for nitrous oxide processing in oxygen. The silent discharge stabilized dielectric barrier combined with TiO, bed packing has been applied for tetrachloromethane conversion to chlorine in argon and oxygen. The conversion ratę of nitrous oxide, as well as the coiwersion ratę of nitrous oxide to NO, was studied as a funetion of specific energy. The conversion ratę of nitrous oxide to elements and NO and the conversion ratę of nitrous oxide to NO increased when granular dielectric materials TiO,, SiO, (ąuartz glass), and y-Al,O3 were introduced into the discharge space. The effect of interelectrode space filling with granulated TiO2 on conversion ratę of CC14 to chlorine in silent discharge was observed.
