A gliding discharge reactor supplied by a ferro-resonance system for liquid toluene decomposition

The paper presents results of toluene decomposition performed in a gliding discharge reactor with a conical chamber and six high-voltage electrodes. The electrodes of this plasma reactor are supplied by a 6-phase ferro-resonance system composed of resonant capacitors and stray inductances of the high voltage transformers supplied from a digital inverter. The overall toluene conversion mainly depended on the initial C7H8 concentration and gas flow rate. It was possible to achieve a complete toluene conversion. Moreover, soot or higher hydrocarbons were not formed in this large-scale gliding discharge reactor.

Conversion of tetrachloromethane in large scale gliding discharge reactor

Abstract Gliding discharge plasma in a large scale reactor was used for decomposition of tetrachloromethane. The new power supply system based on a power inverter was used. The conversion of CCl4 was investigated in air at normal pressure. The reactor was made of a quartz-glass tube 60 mm in diameter and contained three converging electrodes 140 mm long. Effects of the initial CCl4 concentration, gas flow rate and discharge power on CCl4 conversion have been studied. The conversion of CCl4 was high in all cases reaching a maximum of 90%. The conversion of tetrachloromethane decreased with increasing initial concentration of CCl4 in the reaction mixture. Changing the gas flow rate from 1000 Nl h-1 to 1400 Nl h-1 decreased the conversion of tetrachloromethane.

Plasma Flow and Temperature in a Gliding Reactor with Different Electrode Configurations

This paper deals with the plasma flow shape depending on the electrode form of a gliding discharge plasma-chemical reactor, and with the temperature distribution along the direction of the plasma flow in one specific electrode form. The shape of the electrodes and their mutual position has a significant influence on the design of a gliding discharge reactor and its applications. It is crucial to know the temperature distribution in the reactor’s chamber design and discharge application. Three configurations with model shapes of wire electrodes were therefore tested (low-divergent, circular, high-divergent) and the plasma flow was described. The experiments were performed in air at atmospheric pressure and at room temperature. In order to map the reactive plasma region of the flow we investigated the visible spectral lines that were emitted. The gas temperature was measured using an infrared camera.
