| 摘 要： | 以高游离脂肪酸含量的大豆酸化油为原料,在较高的压力和温度条件下,经催化甲酯化制备生物柴油,研究了甲酯化的优化反应条件并在此条件下对大豆酸化油、菜籽酸化油、地沟油的甲酯化效率进行了验证试验。结果表明在醇油质量比1:1.25,催化剂NaA/MgR用量为油质量的 1%,压力 3.0 MPa,温度 188℃,反应时间 120 min,3种原料油脂总脂肪酸甲酯含量达到 95%,生物柴油得率在 94% 左右。所得生物柴油产品质量指标符合ASTM 6751-03a的质量指标,且本工艺可以实现工业化。

| Abstract: | Biodiesel was prepared by catalytic methyl esterification under higher pressure and higher temperature from acidic soybean oil with high content of free fatty acids. Optimal conditions for methyl esterification were studied and verified by methyl esterification of acidic soybean oil, acidic rapeseed oil, and waste oil. The content of total fatty acid methyl esters and yield of biodiesel was 95% and 94%, respectively, under the conditions of mass ratio of methanol to oil 1:1.25, catalyst NaA/MgR 1% by weight to oil, pressure 3.0MPa, reaction temperature 188℃, reaction time 120 min. After refination the biodiesel products quality can meet ASTM 6751-03a specification. This technology can be used for industrialization. |
