“…The design of plasma-chemical reactor is based on a three-electrode system, which was developed in [12,13] for generation of stable volumetric gas discharges in various atomic and molecular gases. The reactor consists of threesectional (A, B and C) discharge chamber 1 (Fig.…”

“…Different types of atmospheric pressure discharges (corona, spark, a barrier, gliding arc at DC, AC and pulsating current of different frequency bands) are proposed as plasma sources for these purposes [6][7][8][9][10][11]. This paper is focused on ethanol to syngas conversion assisted by a DC atmospheric pressure discharge with plasma cathode [12,13]. Along with the description of the facility, experimental conditions and measurements we present the results of mathematical modeling of the process under consideration which are obtained using the same approach as explained in [14], although the kinetic mechanism for ethanol conversion applied as listed in [15].…”

Abstract:Complex theoretical and experimental investigation of ethanol into syngas conversion assisted by DC atmospheric pressure discharge with plasma cathode is presented. Infrared absorption spectroscopy together with the equation for the conservation of the number of atoms at the inlet and outlet of the reactor are used to determine the composition of syngas, the main components of which are hydrogen, carbon monoxide, methane and acetylene. It is shown that the plasmachemical reactor enables efficient (over 90%) ethanol into syngas conversion with an output of 2 L min -1 and at energy costs of about 3 electron-volts per one hydrogen molecule. Numerical modeling of conversion kinetics at discharge conditions was performed assuming thermal nature of the process. Experimental and calculated data are in good agreement.

“…In these experiments, different electrode-polarity combinations were examined to exclude, in turn, the anode and cathode falls. As it was pointed but not demonstrated in [17], the three-electrode system can be used to produce a large-volume discharge in different gas mixtures. We confirm this conclusion by the results presented as follows.…”

“…The possibility of obtaining a large-volume non-selfsustained atmospheric-pressure glow discharge (APGD) with help of the self-sustained normal dc APGD in helium [16] is demonstrated in [17]. A self-sustained normal dc APGD in helium is created in the hermetic section of a discharge chamber separated from the main section by a copper plate with a hole.…”

Nonthermal non-self-sustained dc glow discharge in atmospheric-pressure air was developed in a three-electrode configuration. A self-sustained normal dc atmospheric-pressure glow discharge in helium served as a "plasma cathode" for the main discharge in ambient air. Conditions of discharge transfer from helium volume to atmospheric air are under investigation. It is shown that a smooth transfer between the discharges in both volumes takes place only at small gaps between the "plasma cathode" and the third electrode (less than 5 mm) as the voltage applied to the air gap is increased. For larger gaps, this transfer is accompanied by discontinuous changes in both the voltage and current. After the jump, the discharge is contracted. But if the interelectrode gap is increased (more than 10 mm), then two forms of the discharge exist in one discharge space: diffuse and contracted.Index Terms-Atmospheric-pressure air plasma, atmosphericpressure glow discharge (APGD), glow discharges, plasma generation, plasma measurements.
