Abstract

[...]depending on the molecular structure of these FAMEs (molecular branching or unsaturations, mainly), their degradation will be longer or shorter, implying a quality loss of biodiesel (FAME loss and increase in viscosity, mainly) [37,38] and not complying with the standards for its marketability, at least, as a pure biofuel [39]. [...]the mixture with other more stable biodiesel [40], the use of antioxidants (both natural and artificial) [41,42,43,44,45], and other chemical reactions [34] have been attempted in order to increase the oxidative stability of biodiesel samples, to revalue this product. Biodiesel Characterization As it can be seen in Table 4, most characteristics of Safflower biodiesel complied with the EN-14214 [39]. [...]it was a biofuel with a high yield in FAMEs and suitable characteristics for warm climates (acidity number, viscosity, and density showed intermediate values and cold filter plugging point was within the limits for warm climates, not for cold ones). [...]the effect of the addition of antioxidants on some biodiesel characteristics, especially viscosity, should be taken into account, especially when the concentration of antioxidant required is high (because of the extreme low oxidative stability of biodiesel in certain cases) or the viscosity of biodiesel is close to the upper limit of the standard.
