Abstract
The PREMIX code in conjunction with Chemkin II and models resulting from the merging of
validated kinetic schemes describing the oxidation of the components of the n butanol–benzene mixtures
were used to investigate the effect of n butanol addition on the formation–depletion of cyclopehtadienyl rad
ical (C5H5), a soot precursor in the flames of mixtures of n butanol–benzene formed under fuel rich condi
tions. The first part of this study deals with the validation of the proposed combined model on benzene and
n butanol flames. The second part describes the dependence of the amount of cyclopentadienyl radical on
the percentage of benzene replacement by oxygenate additive. The third part deals with the causes of the vari
ation of mole fractions of this species with n butanol. The principal objective of this work was to obtain fun
damental understanding of the mechanisms through which an oxygenate affects amounts of C5H5. It was
found that the cyclopentadienyl radical concentration was lower in the flame of the n butanol–benzene fuel
mixture than in the pure benzene flame.
