Abstract

The cold flow properties of waste oil biodiesel (WME) were studied by gas chromatography-mass spectrometry (GC-MS), multifunctional low temperature tester, differential scanning calorimetry (DSC) and solution crystallization theory. Three approaches for reducing cold filter plugging point (CFPP) of WME were investigated: crystallization fractionation, blending with winter petrodiesel and treating with cold flow improver (CFI) additives. A good correlation model was proposed for prediction CFPP by WME blending ratio. The study shows that the WME was mainly composed of fatty acid methyl esters (FAME): C14∶0–C22∶0, C16∶1–C22∶1, C18∶2 and C18∶3. The mass fraction of saturated fatty acid methyl esters (SFAME) and unsaturated fatty acid methyl esters (UFAME) was 31.04% and 64.51%, respectively. The CFPP of WME was 3 °C. Crystallization fractionation and blending with −10 petrodiesel (−10PD) decreased the CFPP to −2 and −12 °C respectively. Treating with CFI additives (volume fraction ≤ 0.5%) decreased the CFPP of WME and WME/−10PD to −1 and −26 °C, respectively. This study has effectively improved cold flow properties of WME and provided guide for using WME during cold weather.

废油生物柴油冷流特性研究及改进

采用气相色谱-质谱(GC-MS)、多功能低温测试仪、差示扫描量热法(DSC)和溶液结晶理论对废油生物柴油(WME)的冷流动特性进行了研究。采用结晶分馏、与冬季石油柴油共混、添加冷流改进剂等3种方法降低冷滤芯堵塞点。提出了一种较好的WME混合比预测CFPP的相关模型。研究表明，WME主要由脂肪酸甲酯(FAME)组成:C14∶0 ~ c22∶0、C16∶1 ~ c22∶1、C18∶2和C18∶3。饱和脂肪酸甲酯(SFAME)和不饱和脂肪酸甲酯(UFAME)的质量分数分别为31.04%和64.51%。WME的CFPP为3°C。结晶分馏和与- 10石油柴油(- 10PD)共混使CFPP分别降至- 2℃和- 12℃。CFI添加剂(体积分数≤0.5%)使WME和WME/ - 10PD的CFPP分别降至- 1和- 26°C。该研究有效地改善了WME的冷流性能，为在寒冷天气下使用WME提供了指导。
