“…This analysis enabled the determination of current pulse parameters, including the number of pulses within each 2 min interval, the duration of each pulse, the total discharge exposure time, and the amplitude (maximum current) of each pulse. The average values (Table 1) were then calculated using the method described in [47]. Typical oscillograms of current and voltage pulses of plasma-chemical pyrolysis of fuel oil at 300-700 V are shown in Figure 2.…”

“…A 40 cm 3 reactor with pulsed discharges in the liquid phase generated by one automatically moving electrode was used. Pulsed discharges in the liquid phase were generated by the automatic movement of an electrode according to a predetermined algorithm using the control system [46,47]. The developed principle for generating electric discharges, control system, and plasma reactor are effective for inducing chemical processes.…”

A pulsed plasma pyrolysis reactor with an efficient control system was designed for fuel oil processing. Non-thermal plasma pyrolysis was carried out in the liquid phase at low temperatures (not higher than 100 °C) in a 300 cm3 reactor without additional reagents or catalysts. The main process parameters and characteristics of non-thermal plasma fuel oil products were investigated within the DC source voltage range of 300–700 V. An increase in the energy of pulsed discharges led to an increase in the productivity of the plasma pyrolysis process and the yield of hydrogen but reduced the yield of acetylene and ethylene. The resulting gas consisted predominantly of hydrogen (46.5–50.0 mol%), acetylene (28.8–34.3 mol%), ethylene (7.6–8.6 mol%), methane (4.2–6.2 mol%), and C3–C5 hydrocarbons. The solid-phase products were in the form of disordered graphite and multilayer nanotubes.

“…When conducting any process using plasma, knowledge of its properties and mastery of the methods for obtaining it should be ensured. Plasma research focuses on obtaining controlled plasmochemical reactions [1][2][3][4][5]. The constancy of the parameters of the generated plasma largely determines the reproducibility of the processes carried out with its participation [6].…”

Three-phase gliding arc discharge reactors are devices in which it is difficult to maintain stable plasma parameters, be it electrically, physically, or chemically. The main cause of plasma instability is the source, which is freely burning arcs in a three-phase system. In addition, these arcs burn at low currents and are intensively cooled, further increasing their instability. These instabilities translate into the electrical characteristics of the plasma reactor. The analysis for the four gases nitrogen, argon, helium, and air shows that the type of plasma-generating gas and its physical parameters have a strong influence on the operational characteristics of the plasma reactor. Current–voltage, power and frequency characteristics of the plasma reactor were plotted experimentally. Characteristics obtained in this way make it possible to determine the areas of effective operation of the plasma reactor, and to estimate the quality of the generated plasma. Based on the characteristics obtained, a method of controlling the plasma parameters can be developed.

The constant growth in the share of renewable electricity and the need to reduce CO2 emissions create prospects for the development of non‐thermal plasma (NTP) pyrolysis of heavy oil. NTP pyrolysis requires only electricity and does not require heating of raw materials to high temperatures, which significantly reduces the carbon footprint during processing. This paper investigates the characteristics of NTP pyrolysis of vacuum gas oil under the action of electric microsecond discharges in the liquid phase, depending on the voltage of the current source 300–700 V to optimize energy consumption, conversion of raw materials, and increase the yield of commercial demand products.
