Abstract The synergetic interplay between the removal of saturated methyl esters and the addition of deoxygenated fatty acids on depressing the cloud point temperature of biodiesel was investigated in this study. Canola biodiesel was produced in batch as a standard with a cloud point of 1.37 +/- 6.3°C. Saturated methyl esters were removed from the standard via urea fractionation resulting in a low saturate biodiesel with a cloud point of -21.06 +/- 0.5°C. Heptadecene was used as a standard for the major products produced from the deoxygenation of saturated fatty acids. Heptadecene was blended in ratios of 1 to 5 wt% in both the standard and low saturate biodiesel. The standard biodiesel blended with heptadecene did not show any statistically significant shift in the mean cloud point over the range. The low saturate biodiesel blended with heptadecene showed statistically significant deviations from the mean at 2, 4, and 5 wt%. A pseudo-eutectic system was observed between heptadecene and low saturate biodiesel with a minimum cloud point of -25.16 +/- 2.5°C at 2 wt% Heptadecene.
