THE DILUTED STOICHIOMETRIC OXIDATION OF ISO-OCTANE IN THE INTERMEDIATE TEMPERATURE REGIME AT ELEVATED PRESSURES

Abstract

Experimental and modeling results for dilute stoichiometric oxidation of iso-octane in the intermediate temperature regime are presented for pressures of 6 and 9 atmospheres. While the overall comparison between the experiments and modeling is acceptable, important differences exist in the predictions of the mole fractions of acetone and methacrolein, which are products of iso-butene oxidation. The results from this study arc compared to earlier work on the oxidation iso-octane under very lean conditions to illustrate the significance of chemical pathways in which molecular oxygen is a key reaclant.
