Special Issue Information

Dear Colleagues,

With fast-paced changes in global energy, the fuel market, and related policies, plasma may become an important element. The constant increase in the share of renewable electricity sources along with depleting resources of fossil fuels creates a strong foundation for plasma application. Processes such as biomass and waste gasification/pyrolysis, coal combustion, steam reforming of methane and other organic compounds, methane coupling, dry reforming, syngas cleaning, and many others that involve plasma sources, whether thermal or nonthermal, have been recently undergone intensive investigation.

This Special Issue aims to present the most recent advances in these areas, as well as new applications and concepts of plasma use in fuel conversion, and gather and compare achieved results.

Topics of interest for publication include, but are not limited to, the following plasma applications (both thermal and nonthermal):

  • Solid fuel conversion (combustion, gasification, pyrolysis, steam reforming);
  • Hydrogen production;
  • Methane activation and coupling;
  • Dry reforming;
  • CO2 conversion into fuels;
  • Carbon material production;
  • Cleaning of fuel conversion products (e.g., syngas or fumes);
  • Plasma/catalytic systems for fuel conversion;
  • Modelling of plasma fuel conversion processes;
  • Design and measurement of plasma torches and reactors in the context of fuel conversion.

This study examines the sustainable decomposition reactions of benzene using non-thermal plasma (NTP) in a dielectric barrier discharge (DBD) reactor. The aim is to investigate the factors influencing benzene decomposition process, including input power, concentration, and residence time, through kinetic modeling, reactor performance assessment, and machine learning techniques. To further enhance the understanding and modeling of the decomposition process, the researchers determine the apparent decomposition rate constant, which is incorporated into a kinetic model using a novel theoretical plug flow reactor analogy model. The resulting reactor model is simulated using the ODE45 solver in MATLAB, with advanced machine learning algorithms and performance metrics such as RMSE, MSE, and MAE employed to improve accuracy. The analysis reveals that higher input discharge power and longer residence time result in increased tar analogue compound (TAC) decomposition. The results indicate that higher input discharge power leads to a significant improvement in the TAC decomposition rate, reaching 82.9%. The machine learning model achieved very good agreement with the experiments, showing a decomposition rate of 83.01%. The model flagged potential hotspots at 15% and 25% of the reactor’s length, which is important in terms of engineering design of scaled-up reactors. Full article

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. Full article

With the increasing role of hydrogen in the global market, new ways of hydrogen production are being sought and investigated. One of the possible solutions might be the plasma pyrolysis of methane. This approach provides not only the desired hydrogen, but also valuable carbon-containing products, e.g., carbon black of C2 compounds. This review gathers information from the last 20 years on different reactors that were investigated in the context of methane pyrolysis, emphasizing the different products that can be obtained through this process.
