abstract in this work, the dry reforming of methane was studied using a corona and glow discharge plasma microreactors. a chemical kinetic model was developed to understand the reaction better. the modelization allowed prediction of the reactants conversion according to the energy transfer to the gas (p×τ). the β value is trait of the energy cost, whatever this value was leeser indicated better...

Atmospheric pressure corona discharges are used in electrophotographic (EP) printing technologies for charging imaging surfaces such as photoconductors. A typical corona discharge consists of a wire (or wire array) biased with a few hundred volts of dc plus a few kV of ac voltage. An electric discharge is produced around the corona wire from which electrons drift towards and charge the underlyi...

The use of electrical corona discharge opens broad possibilities for effective development of electrostatic precipitators (ESPs). The object of the work is the study of the corona discharge in different gases at high temperature / high pressure (HT/HP) conditions. The studies are carried out in a HT/HP ionizer in the pure synthetic air, N2, He and He-synthetic air and He-N2 gas mixtures. Corona...

The efficiency of ozone generation in DC corona discharge fed by carbon dioxide has been studied. A simple coaxial system of electrodes has been used for generation of both negative and positive corona discharge in flowing gas. The ozone concentration has been measured on the outlet of the reactor by UV absorption spectroscopy methods. Ozone generation in the negative corona discharge was found...

since nox family, one of the most important causes of air pollution, is the primary source of acid rains, ozone layer depletion, and breathing disorders, mitigation of these pollutants is now a global concern. in the off-gases of internal combustion engines running with oxygen excess, non-thermal plasmas (ntps) have an oxidative potential, which results in an effective conversion of no to no2. ...

This study investigates the possibility of corona discharge ionization technique for reduction of fog. For corona discharge ionization a high voltage power supply is designed and developed indigenously. The high output voltage is developed by using isolation transformer, autotransformer, and high voltage neon transformer and it is converted into DC voltage by using Wheatstone bridge circuit and...

It is well known that the time-varying parametric model based on wavelet neural network has excellent performance on modeling a signal. The spark discharge signal is a typical nonstationary one. The spark discharge has two types in a static dust catcher. one is normal discharge, another is antielectric-corona discharge. A few simulations indicate that the performance of the TVAR model on modeli...

We resolved the controversial assignments of the visible vibronic bands observed from corona discharge of 1,2,3-trimethylbenzene. The vibronic bands belonging to the jet-cooled 2,6-dimethylbenzyl radical were clearly identified from the spectrum observed from corona discharge of 2,6-dimethylbenzyl chloride. After subtracting the bands of the 2,6-isomer from the spectrum observed from corona dis...
