Kinetic modeling of the low temperature reactivity of n-butanol

The aim of this paper is to analyze and discuss a kinetic mechanism able to describe the low temperature reactivity of n-butanol. Using a lumped approach, already successfully adopted for the low temperature mechanism of n-alkanes, an existing mechanism of n-butanol pyrolysis and combustion is extended to include the low temperature reactivity. The model is validated in a wide range of conditions (P=1÷80 atm, T=500÷1500 K), using recent autoignition data measured in shock tubes and detailed species profiles measured in Jet Stirred Reactors (JSR). The comparisons between the experimental data and model predictions further confirm the validity and the broad applicability of the kinetic model.
