“…These species can selectively activate specific chemical bonds or functional groups in a molecule, leading to specific reaction pathways that may not be accessible through conventional chemical methods [27,28]. The utilization of NTP for chemical processes enables strongly endothermic reactions at moderate temperatures, limiting joule heating effects and thereby minimizing energy loss through heating the reactant mass [29][30][31]. This attribute renders plasma processes energetically efficient and promising for thermocatalytic reactions, which are customarily executed at elevated temperatures and pressures.…”

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.

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.

The non-thermal plasma pyrolysis of fuel oil, under the action of low-voltage electric discharges in the liquid phase, has made it possible to develop a new process to obtain valuable petrochemical products. In this study, the main parameters, including pulse energy and the time of impact on the non-thermal plasma pyrolysis process, are studied. The main components of the obtained gaseous products are hydrogen (27.6–49.6 mol%), acetylene (33.6–49.1 mol%), ethylene (6.9–12.1 mol%), methane (3.9–9.1 mol%), and hydrocarbons C3-C5 (3.8–9.3 mol%). Increasing the capacity of electric discharges leads to an increase in the content of acetylene in the gas phase to 49.1 mol% and a decrease in energy costs for the production of gaseous products.
