EXPERIMENTAL AND MODELING STUDY OF THE OXIDATION OF FENCHONE, A HIGH-ENERGY DENSITY FUEL-ADDITIVE

Résumé

Increasing fuel energy density constitutes a potential way to reduce engine exhaust carbon emission. Fenchone, a strained ring molecule, is an interesting candidate. The present study investigates the oxidation of fenchone in a jet-stirred reactor at high pressure (10 atm) between 700 and 1180 K at constant fuel mole fraction and constant residence time of 0.1% and 0.7s, respectively. Mole fraction profiles were obtained through sonic probe sampling, and analyzed by gas chromatography and Fourier transform infrared spectrometry. More than 30 species were identified and most of them were quantified. Also, a kinetic mechanism was developed in this study and tested against the present experimental conditions showing good agreement. The present mechanism allows illuminating the major reaction pathways involved in the decomposition routes of the fuel and its primary radicals as well as the formation pathways of the quantified intermediate species. During fenchone oxidation, the carbonyl group is mostly concerted into CO, CO2 and formaldehyde while higher carbonyl species were identified at much lower levels of concentration, indicating that decarbonylation occurs early during the oxidation process. Aromatic compounds such as benzene and toluene are formed especially in fuel-rich conditions and potential oxygenated pollutants such as methacrolein and acetaldehyde were also quantified.
