Special Issue Information

Dear Colleagues,

The increasing demand for sustainable energy solutions has intensified research on alternative fuels and clean combustion technologies. With the global push to reduce greenhouse gas emissions and dependence on fossil fuels, alternative fuels such as hydrogen, ammonia, biofuels, and synthetic fuels are gaining significant attention. Concurrently, advancements in clean combustion strategies—including low-NOx burners, advanced ignition systems, and novel combustion modes—are critical for enhancing energy efficiency and minimizing environmental impact. These developments are essential not only for power generation and transportation but also for broader applications in industrial systems where carbon neutrality is a growing priority.

The Special Issue aims to provide a comprehensive platform for the latest advances in alternative fuel utilization and clean combustion techniques. It welcomes contributions related to experimental studies, numerical modeling, and theoretical analyses that promote cleaner and more efficient combustion systems.

Topics of interest for publication include, but are not limited to, the following:

  • Alternative fuel combustion (hydrogen, ammonia, biofuels, synthetic fuels, etc.);
  • Low-emission combustion technologies;
  • Combustion modeling and simulation;
  • Chemical kinetics of alternative fuels;
  • Advanced ignition strategies and control methods;
  • Engine and gas turbine applications using clean fuels;
  • Combustion diagnostics and measurement techniques;
  • Emission control and aftertreatment systems;
  • Combustion stability and flame dynamics;
  • Hybrid and co-firing combustion systems;
  • Fuel reforming and pre-treatment technologies;
  • Techno-economic and environmental assessments of clean combustion systems.

Xylenes are important components of gasoline fuels, and their hydrogen abstraction reactions are crucial in the consumption pathways of combustion processes. In existing models, rate constants for these reactions are commonly derived by estimation, which can introduce large uncertainties into models and lead to prediction deviations. In this study, the hydrogen abstraction reactions of three xylene isomers (p-xylene, m-xylene, and o-xylene) with hydrogen and hydroxyl radicals were investigated using quantum chemical methods. The high-precision CBS-QB3 method was used to perform a series of calculations, including structure optimization, frequency analysis, and energy calculations. Rate constants for all reactions were obtained using transition state theory with tunneling corrections and fitted to the three-parameter Arrhenius expression. The kinetic parameters of these reactions were updated in existing models of xylene. The integration of the updated rate constants into combustion models generally improves predictive accuracy, particularly for ignition delay times, CO2 formation, and laminar flame speeds, although discrepancies remain for some species such as CO.
