“…Moreover, biodiesel is an environment-friendly option that can be cheaper than other kind of additives. Biodiesel-diesel blends have been widely studied and it is well known that biodiesel reduces the particulate matter and CO emissions and increases cetane number and flash point of diesel in blends [4][5][6]. In addition, biodiesel may not require engine modifications when used in blends up to 20% (m/m) in diesel, as far as cold-flow properties are the required ones for the climate conditions [7].…”

Lubricity of individual fatty acid methyl or ethyl esters and biodiesel fuels has been measured using a high frequency reciprocating rig (HFRR). Tests have been carried out varying the ambient humidity to assess the effect of this parameter on the lubricity of the fuels. The European standard proposes a single humidity correction factor for al! the fuels, regardless their composition. lt has been proved in this study that this factor is not constant and it depends on the fu el composition. For this reason two different correlations have been proposed for the estimation of the humidity correction factor and normalized wear scar as a function of different fuel compositional characteristics. The infiuence of the water content on the lubricity and the relationship between humidity and water content ofthe fuel has been studied revealing that the effect of the air humidity is an indirect effect of the hygroscopy of the fue!.

“…Biodiesel, referred to as mixtures of fatty acid mono-alkyl esters with relatively high contents of long-chain, monoand poly-unsaturated compounds, is produced from vegetable oils and animal fats by transesterification with alcohols of low molecular weights over catalysts (Candeia et al 2009;Leung et al 2010;Moser and Vaughn 2010). Fatty acid methyl esters (FAME) such as soybean methyl ester (SME) are typically mixtures of esters with 16-18 carbon atoms, where 80 %-85 % (w/w) of the mixture is unsaturated (Knothe et al 2005).…”

Thermal decomposition characteristics and kinetics of methyl linoleate under nitrogen and oxygen atmospheres

The thermal decomposition characteristics of methyl linoleate (ML) under nitrogen and oxygen atmospheres were investigated, using a thermogravimetric analyzer at a heating rate of 10°C/min from room temperature to 600°C. Furthermore, the pyrolytic and kinetic characteristics of ML at different heating rates were studied. The results showed that the thermal decomposition characteristics of ML under nitrogen and oxygen atmospheres were macroscopically similar, although ML exhibited relatively lower thermal stability under an oxygen atmosphere than under a nitrogen atmosphere. The initial decomposition temperature, the maximum weight loss temperature, the peak decomposition temperature, and the rate of maximum weight loss of ML under an oxygen atmosphere were much lower than those under a nitrogen atmosphere and increased with increasing heating rates under either oxygen or nitrogen atmosphere. In addition, the kinetic characteristics of thermal decomposition of ML were elucidated based on the experimental results and by the multiple linear regression method. The activation energy, pre-exponential factor, reaction order, and the kinetic equation for thermal decomposition of ML were obtained. The comparison of experimental and calculated data and the analysis of statistical errors of pyrolysis ratios demonstrated that the kinetic model was reliable for pyrolysis of ML with relative errors of about 1 %. Finally, the kinetic compensation effect between the preexponential factors and the activation energy in the pyrolysis of ML was also confirmed.
