利用气相色谱-质谱分析废弃油脂生物柴油( WME )的化学组成,利用低温差示扫描量热仪和冷滤点测试仪研究WME的低温流动性能。采用结晶分离、与-10号柴油(-10PD)调合、添加低温流动性改进剂(Flow Fit、Flow Fit K和T818)降低WME的冷滤点(CFPP)。结果表明：WME主要由14~22个偶数碳原子的脂肪酸甲酯组成,其中饱和脂肪酸甲酯和不饱和脂肪酸甲酯的含量分别为31.04%和64.51%。 WME的晶体初析温度和CFPP分别为1.1、3℃；与-10PD调合,B20~B30的CFPP降至-12℃；添加0.1% Flow Fit K,WME、B80、B60、B40、B20、B10和B5的CFPP分别从3、-1、-5、-9、-12、-9℃和-8℃降至-1、-4、-10、-17、-24、-24℃和-26℃。

The chemical composition of waste oil biodiesel ( WME) was analyzed by GC -MS,and the low-temperature fluidity of WME was studied by low temperature differential scanning calorimetry and cold filter plugging point ( CFPP) tester. Three approaches for reducing CFPP of WME were investigated including crystallization fractionation, blending with -10PD and adding cold flow improvers ( Flow Fit, Flow Fit K and T818 ) . The results showed that WME was mainly composed of fatty acid methyl esters with 14-22 of even number carbon atoms, in which the contents of saturated and unsaturated fatty acid methyl esters were 31. 04% and 64. 51%, respectively. The initial crystallization precipitation tempera-ture and CFPP of WME were 1. 1℃ and 3℃, respectively. Blending with-10PD, the CFPP of B20-B30 decreased to -12℃. The CFPPs of WME, B80, B60, B40, B20, B10 and B5 added with 0. 1%of Flow Fit K decreased from 3 , -1 , -5 , -9 , -12 , -9 ,-8℃ to -1 , -4 , -10 , -17 , -24 ,-24,-26℃, respectively.
