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 translation: 本发明涉及一种用于改善具有高饱和脂肪酸含量的动植物油和脂肪的生物柴油的低温流动性的方法，更具体地说，涉及通过以下方法提高生物柴油的低温流动性的方法： 结合生物柴油的低温流动性的方法，通过向具有高含量的饱和脂肪酸甲酯的生物柴油中加入尿素和甲醇以降低饱和脂肪酸甲酯的含量和改善冷滤器堵塞点的方法（ CFPP）通过将添加剂（CFPP-抑制剂添加剂）与生物柴油二次混合，使饱和脂肪酸甲酯的含量降低，以使效率最大化。 根据本发明，具有高饱和脂肪酸甲酯含量的生物柴油的冷滤器堵塞点得到改善，因此可以在家庭环境条件下获得更有利的作为燃料油的生物柴油。

Abstract: 본발명은포화지방산함량이높은동물성및 식물성유지바이오디젤의저온유동성개선방법에관한것으로서, 더욱상세하게는포화지방산메틸에스테르함량이높은바이오디젤에요소와메탄올을첨가하여포화지방산메틸에스테르함량을저감시켜바이오디젤의저온유동성을개선하는방법, 그리고포화지방산메틸에스테르함량이저감된바이오디젤에이차적으로첨가제(CFPP-depressant additives)를혼합하여저온필터막힘점(CFPP)을개선하는방법을복합적으로적용하여그 효율성을극대화함으로써바이오디젤의저온유동성을크게개선하는방법에관한것이다. 본발명에의하면포화지방산메틸에스테르함량이높은바이오디젤의저온필터막힘점을개선함으로써국내환경조건에서보다유리한연료유로적용가능한바이오디젤을얻을수 있다.
