Abstract: The present invention relates to a method for improving the low-temperature fluidity of biodiesel from animal and vegetable oils and fats with a high content of saturated fatty acid and, more particularly, to a method for improving the low-temperature fluidity of the biodiesel by combining a method for improving low-temperature fluidity of biodiesel by adding urea and methanol to biodiesel with a high content of saturated fatty acid methyl ester to reduce the content of the saturated fatty acid methyl ester and a method for improving a cold filter plugging point (CFPP) by secondarily mixing additives (CFPP-depressant additives) with the biodiesel with a reduced content of saturated fatty acid methyl ester to maximize the efficiency. According to the present invention, the cold filter plugging point of the biodiesel with a high content of saturated fatty acid methyl ester is improved, and thus the biodiesel that is applicable as a fuel oil which is more advantageous can be obtained in domestic environmental conditions.

Abstract: PURPOSE: A low temperature fluidity improvement method is provided to improve physical property of animal and vegetable oil capable of being applied to a fuel by adding vegetable oil after reacting animal biodiesel by adding urea. CONSTITUTION: A low temperature fluidity improvement method of animal oil originated biodiesel includes a stage of adding urea to animal oil originated biodiesel; a state of forming an incision compound by condensing saturated fat acid methylester included in the animal oil originated biodiesel and urea; and a stage of removing the incision compound. The weight ratio of the animal oil originated biodiesel and urea is to be 1:0.5-3. The animal oil originated biodiesel is made of tallow, lard or a mixture of tallow and lard. A low temperature fluidity improvement method of vegetable oil originated biodiesel includes a stage of reducing the amount of saturated fat acid methylester; and a stage of mixing vegetable oil originated biodiesel with the animal oil originated biodiesel having the amount of saturated methylester reduced. The vegetable oil is made of more than one between rape seed oil, camellia oil, soybean oil and waste edible oil. The volume ratio between the animal oil originated biodiesel having the amount of saturated methylester reduced and the vegetable oil originated biodiesel is to be 1:0.25-4. [Reference numerals] (AA) C14:0 - myristic acid; (BB) C16:0 - palmitic acid; (CC) C18:0 - stearic acid; (DD) Saturated fatty acid : 3.38%; (EE) Cold flow plug point = -15°C
