Abstract
In this work, differential scanning calorimetry and X-ray diffraction techniques were employed to evaluate the influence of the winterization process on the low temperature properties of methyl babassu biodiesel. The results have shown that the crystallization onset temperature for the non-winterized biodiesel is around 266.4 K (−6.6 °C) which is reduced to 263.6 K (−9.4 °C) for the liquid fraction of winterized biodiesel. The 14 % reduction in the amount of saturated fatty acid methyl esters is probably responsible for the improvement of low temperature properties of winterized methyl babassu biodiesel.
