Abstract
The energy efficiency of electric pulse installation based on a high-current plasma accelerator was investigated. A series of experiments with different central electrodes was carried out. The system based on carbon electrodes has a greater value of the charge energy conversion into the energy of arc discharge and the less discharge current level in comparison with other electrode systems. The power consumption value for producing 1 gram of powdered product was estimated and it was found this value is comparable to the work of the LED light bulb for 1 hour.
Highlights
A number of materials with unique properties, that make them suitable for renewable energy in order to produce hydrogen from water, are well-known
Considering the first group of experiments (Table 1, items 1 and 2), connected with the generation of tungsten-carbon electrical discharge plasma flow, it is seen that the power amplitude and the amount of released energy is more when the graphite central electrode is used for
The ratio of the energy of the arc discharge in the accelerator, referred to the energy of the supply source, is significantly higher when using the graphite tip of the central electrode
Summary
A number of materials with unique properties, that make them suitable for renewable energy in order to produce hydrogen from water, are well-known. There are reports about the high photocatalytic activity of ultrafine tungsten carbides and carbon nitrides [1,2,3,4] These materials can conceivably replace the precious and rare metals of "platinum group" in the catalyst systems. The electro discharge technology based on plasma acceleration processes can be used to obtain tungsten carbides and carbon nitrides in the ultrafine form [5,6]. This technology is in the stage of research work, this is why the difficult task is the assessment of its cost-effectiveness. To investigate the ways of the possible improvement of the energy efficiency of the installation based on pulse coaxial plasma accelerator, the series of experiments with constant parameters of the pulsed power supply and different materials of the electrode system has been carried out
