The UV-visible spectroscopyin the range from190 to 320 nm wasutilizedtodetectthe ozone formation, in wire-to-cylindercorona reactorwithnegativepolarity. The effectof N2+O2 mixture on ozone production has been investigated. The maximum production of ozone was already corresponding to 70% of oxygen in the gas mixture forany applied voltage...

Positive corona discharge in mixtures of CO2 and N2 has been experimentally investigated using a coaxial wire-to-cylinder corona discharge reactor. Special attention has been paid to the stability of the corona current and to the generation of ozone and nitrogen oxides in time, which are influenced by the applied voltage and the ratio of CO2:N2...

The decomposition of CO2 by the effect of negative corona discharge has been experimentally and numerically investigated for different admixtures of N2. The chemical kinetics model used in the simulation includes a wide variety of reactions between electrons, ions, atoms and molecules, such as ionization and recombination, ...

Ozone generation using a hollow needle-to-plate corona reactor has been investigated using both positive and negative polarities and various flow rates. Oxygen could be introduced in the reactor either through the needle electrode or through a port on the lateral wall. This configuration al-lowed studying the effect of the flow direction on...

Carbon dioxide decomposition in mixtures of CO2and O2has been experimentally investigatedusing dielectric barrier discharge, with special interest on O3and COproductions. Experiments have been conducted at different frequencies and operating voltages, and the concentration of O3and COhave been measured by means of absorption...

The generation of ozone in a coaxial wire-cylinder corona discharge reactor has been experimentally investigated using variable proportions (5% to 90%) of oxygen in nitrogen. The experiments have been carried out under negative polarity and using different gas flow rates (50 cm3/min to 200 cm3/min). The...
