Biofuels are expected to play a significant role in the quest
for greener energy generation. In this perspective, esters
produced from biomass are promising candidates. This work
presents the first computational kinetic study on n-butyl
formate (BF) oxidation under combustion conditions coupled to
an experimental study in a jet-stirred reactor. Absolute rate
constants for hydrogen abstraction reactions by the OH
radical were calculated using the G3//MP2/aug-cc-pVDZ model
chemistry, in conjunction with statistical rate theory (TST).
Subsequently, the fate of the butyl formate radicals was also
investigated by calculating absolute rate constants for
combustion relevant decomposition channels such as β-scission
and hydrogen transfer reactions. The derived rate expressions
were used in the presently developed detailed kinetic
mechanism, which was validated over experimental data
obtained in a jet-stirred reactor at 10 atm and for three
different mixtures (φ = 0.45, 0.9, and 1.8). Rate of
production analyses were finally used to understand the
oxidation kinetics of butyl formate over the temperature
range of 500–1300 K and highlighted the importance of the
unimolecular decomposition reactions of the fuel, producing
formic acid and 1-butene.
