“…8. The two saturated methyl esters, methyl stearate and methyl palmitate, show 31 very similar behavior, with a pronounced low temperature reaction zone extending to about 70% fuel consumption. The only small difference between these fuels can be seen at the minimum values for each curve at about 750K, where the methyl palmitate shows slightly less conversion at this point.…”

A detailed chemical kinetic reaction mechanism is developed for the five major components of soy biodiesel and rapeseed biodiesel fuels. These components, methyl stearate, methyl oleate, methyl linoleate, methyl linolenate, and methyl palmitate, are large methyl ester molecules, some with carbon-carbon double bonds, and kinetic mechanisms for them as a family of fuels have not previously been available. Of particular importance in these mechanisms are models for alkylperoxy radical isomerization reactions in which a C=C double bond is embedded in the transition state ring. The resulting kinetic model is validated through comparisons between predicted results and a relatively small experimental literature. The model is also used in simulations of biodiesel oxidation in jet-stirred reactor and intermediate shock tube ignition and oxidation conditions to demonstrate the capabilities and limitations of these mechanisms.Differences in combustion properties between the two biodiesel fuels, derived from soy and rapeseed oils, are traced to the differences in the relative amounts of the same five methyl ester components. † Lawrence

“…These studies have examined ignition and combustion of alkyl esters from methyl and ethyl hexanoate and methyl and ethyl heptanoate to methyl decanoate [24][25][26][27][28][29][30][31][32][33], followed closely by extensions to methyl stearate and rapeseed methyl ester [34][35][36][37].…”

“…Previous research [33][34][35][36][37][38][39][40][41][42][43] in opposed-flow laminar flames indicates that fuel reactivity is more sensitive to diffusivity estimates than to kinetic rate parameters because transport processes are rate controlling in these systems. Therefore, tuning rate and thermochemical constants to fit nonpremixed flame data is not recommended.…”

Fischer-Tropsch (FT) fuels derived from biomass syngas are renewable fuels that can replace conventional petroleum fuels in jet engine and diesel engine applications. FT fuels typically contain a high concentration of lightly methylated iso-alkanes, whereas petroleum derived jet and diesel fuels contain large fractions of n-alkanes, cycloalkanes, and aromatics plus some lightly methylated iso-alkanes. In order to better understand the combustion characteristics of FT and petroleum fuels, this study presents new experimental data for 2-methylheptane and noctane in an opposed-flow diffusion flame. The high temperature oxidation of 2-methylheptane and n-octane has been modeled using an extended transport database and a reaction mechanism consisting of 3081 reactions involving 608 species. The proposed model shows good qualitative and quantitative agreement with the experimental data. The measured and predicted concentrations of 1-alkenes and ethylene are higher in the n-octane flame, while the concentrations of iso-alkenes (especially iso-butene) and propene are higher in the 2-methylheptane flame. The proposed chemical kinetic model is used to delineate the reactions pathways leading to these observed differences in product species concentrations. An uncertainty analysis was conducted to assess experimental and modeling uncertainties. The results indicate that the simulations are sensitive to the transport parameters used to calculate fuel diffusivity.3
