A study of the preignition oxidation of methane and its sensitization by propane measured ignition delay times behind reflected shock waves at two different locations along the shock tube in 9.5% CH/sub 4/-19% O/sub 2/-Ar mixtures with 0.19, 0.475, 0.95, and 1.9% C/sub 3/H/sub 8/ added. A computer model, comprised of 140 reactions and 34 species, predicted the experimental results obtained in this and earlier studies. The oxidation of methane during the induction period proceeds through three distinct phases: initiation, oxidation of CH/sub 3/ by O/sub 2/, and oxidation of CH/sub 3/ by HO/sub 2/. Sensitization by propane is determined primarily by the decomposition of the propane molecule.
