The laminar premixed flames of n-butylbenzene are studied at lean stoichiometric and rich conditions. A kinetic model of n-butylbenzene was developed and used to describe the decomposition of n-butylbenzene in flames as well as the growth of PAH species. In the premixed flames of n-butylbenzene fuel was mainly consumed via the H-atom abstraction reactions. Unsaturated phenylalkenes and phenyldialkenes played key roles in the formation of indene and naphthalene. Vinylphenyl radical and allylbenzene were the main precursors for indene formation while phenylbutenes and phenylbutadiene were the main precursors for naphthalene formation. The model was validated using the literature data of premixed and diffusion flames of n-butylbenzene.
