摘　　要：以废油脂为原料通过酯交换法制备了生物柴油,测定其凝点为-2℃,闪点为114.5℃,说明生物柴油比-10号柴油具有更高的安全性,但其凝点限制了它的使用范围。采用不同的方法改善生物柴油的低温流动性能,结果表明以生物柴油降凝剂及-10号柴油对生物柴油进行混合降凝的方法,能有效降低生物柴油的凝点,并使其低温流动性能得到改善。Biodiesel was prepared from waste oil by transesterification reaction.Its condensation point and flash point were-2 ℃ and 114.5 ℃,respectivily,Which shows that the biodiesel has more security than-10# diesel,but the higher condensation will limit its use scope.Low-temperature flow performance of the biodiesel was improved by different means.The result shows that mixture condensation means with biodiesel condensation depressant and-10# diesel can reduce condensation effectively and improve low-temperature flow properties.
