Abstract
Concentration profiles of stable hydrocarbons were measured along the centerline of several antisymmetric co-flowing methane/air non-prcmixed flames whose fuels were doped with 2500 to 1900 ppm of benzene, toluene, elhylbenzene. styrene. and phenylacctylene. The results indicate that the H-abstraction/C2H2,-addition mechanism proposed by Frenklach and co-workers was responsible for the naphthalene formed in the undoped, benzene-, styrene-, and phenylacetylene-doped flames. However, a second source of naphthalene, possibly a reaction between benzyl and propargyl radicals, was important in the toluene- and ethylbenzene-doped flames. Soot volume fractions were also measured in each flame; the maximum values correlated well with the maximum naphthalene concentrations, indicating that naphthalene formation is the critical soot formation step for these fuel mixtures containing one-ring compounds.Keywords
