Abstract
Pentanoate esters are seen as a promising new type of biofuels, which can be produced from lignocellulosic material. However kinetic mechanisms for the combustion of pentanoate ester are scarce. Therefore a stoichiometric (ϕ=1.15) and rich (ϕ=1.41) laminar flat flame at 55 mbar was investigated to elaborate on a kinetic mechanism for methyl pentanoate and validate the kinetic model at low pressure, by means of the experimental results. A good agreement between the experimental and simulated mole fraction profiles is found for the main species CO, CO2, H2, O2 and mpe. The concurrence for the intermediates is satisfying, with the exception of formaldehyde (CH2O) and formic acid (HOCHO). A sensitivity analysis of the formation and consumption rates of these two species is performed and a first improvement of the kinetic mechanism is conducted, leading to a better agreement of the experimental and simulated mole fraction profiles of CH2O and HOCHO. Further work will focus on adapting the model to low pressure kinetics and validation of laminar flame speed simulations.
