Advancing sustainable decomposition of biomass tar model compound: Machine learning, kinetic modeling, and experimental investigation in a non-thermal plasma dielectric barrier discharge reactor
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.Web of Science1615art. no. 583
