Embodiment 1
[0034] A biodiesel with low-temperature fluidity, calculated by volume percentage, that is, the composition and content are as follows:
[0035] Coal direct liquefaction hydro-upgrading full distillate oil 2.5%
[0036] Waste oil biodiesel 97.5%.
[0037] A kind of above-mentioned preparation method of biodiesel with low temperature fluidity, the steps are as follows:
[0038] After mixing 97.5ml of gutter oil biodiesel with 2.5ml of coal direct liquefaction hydrogenation and upgrading whole distillate oil, the biodiesel with low temperature fluidity is obtained after standing still for 8-12 hours.
[0039] The biodiesel with low temperature fluidity obtained above has been tested, its cloud point is 1°C lower than that of the sewage biodiesel, and its pour point is 2°C lower than that of the sewage biodiesel. And its pour point, cloud point, flash point, kinematic viscosity, oxidation stability, calorific value, density and acid value all meet the relevant requirements of t...
