EXPERIMENTAL AND KINETIC MODELLING STUDY OF THE OXIDATION OF CYCLOPENTANE AND METHYLCYCLOPENTANE AT ATMOSPHERIC PRESSURE

Abstract : Cyclopentane and methylcyclopentane oxidation was investigated in a jet-stirred reactor at 1 atm, over temperatures ranging from 900 K to 1250 K, for fuel-lean, stoichiometric, and fuel-rich mixtures at a constant residence time of 70 ms. The initial mole fraction of both fuels was kept constant at 1000 ppm. The reactants were highly diluted by a flow of nitrogen to ensure thermal homogeneity. Samples of the reacting mixture were analyzed on-line or off-line by Fourier transform infrared spectroscopy and gas chromatography. A detailed kinetic mechanism consisting of 590 species involved in 3469 reversible reactions was developed and validated against these new experimental results and previously reported ignition delays. Reaction pathways analysis as well as sensitivity analyses were performed to get insights into the differences observed during the oxidation process of cyclopentane and methylcyclopentane.
