Energetic ionic liquids have a high potential to replace the traditional monopropellant hydrazine as a high-energy green propellant and can be widely used in aerospace technology. A high-energy ionic liquid─HEHN has also gained extensive attention from researchers. To explore the reaction mechanism of HEHN and establish a chemical kinetic model for high-energy ionic liquid propellants, 28 hydrogen abstraction reactions of HEH, which is the main decomposition product of HEHN, were investigated in this study.

Cyclohexene is an important intermediate during the oxidation of cycloalkanes, which comprise a significant portion of real fuels. Thus, experimental data sets and kinetic models of cyclohexene play an important role in the understanding of the combustion of cycloalkanes and real fuels. In this work, an experimental and kinetic modeling study of the high-temperature ignition of cyclohexene is performed.

Short-chain fatty acids (SCFAs) generation through anaerobic fermentation has been regarded as a promising pathway to achieve carbon recovery and economic benefits in waste activated sludge management. Despite the cation exchange resin (CER) assistant anaerobic fermentation strategy has been previously reported for enhancing anaerobic fermentation, the overlarge CER usage and serious CER pollution have limited its engineering application. This study provided a reconsideration for the operation pattern modification.

The hydrogen atom abstraction by the methyl peroxy radical (CHO) is an important reaction class in detailed chemical kinetic modeling of the autoignition properties of hydrocarbon fuels. Systematic theoretical studies are performed on this reaction class for H/C-C fuels, which is critical in the development of a base model for large fuels. The molecules include hydrogen, alkanes, alkenes, and alkynes with a carbon number from 1 to 4.

A basic understanding of the high-temperature pyrolysis process of jet fuels is not only valuable for the development of combustion kinetic models but also critical to the design of advanced aeroengines. The development and utilization of alternative jet fuels are of crucial importance in both military and civil aviation. A direct coal liquefaction (DCL) derived liquid fuel is an important alternative jet fuel, yet fundamental pyrolysis studies on this category of jet fuels are lacking.

Article Synopsis
  • A study was conducted using a single-pulse shock tube to analyze the pyrolysis of two concentrations of Chinese RP-3 jet fuel at high pressures and temperatures, identifying major intermediates through gas chromatography.
  • The results showed that ethylene was the most abundant product, along with other significant intermediates like methane, ethane, and benzene, which were quantified using specialized detectors.
  • Kinetic modeling revealed that while some major species predictions were accurate, there is a need to refine current mechanisms for some species, indicating that further research on thermal decomposition is necessary to improve understanding of RP-3 jet fuel combustion.
