| 摘 要： | 采用固定化假丝酵母99-125脂肪酶,对不同地区废油脂在有机溶剂体系下催化合成生物柴油的方法进行了研究。结果表明,对于不同来源组分各异的3种废油脂,经过工艺优化,酯化率分别为89.7%、91.4%和94.7%;在相同条件下,游离脂肪酸(FFA)含量较多的废油脂酯化率高于三甘酯(TAG)含量较多的废油脂。该法对大规模使用酸化油工业化生产生物柴油奠定了基础。

| Abstract: | Immobilized lipase from Candida sp.99-125 was used for catalyzing the synthesis of biodiesel from waste oil in organic solvent system.The result showed that the esterification rate of three kinds of waste oil from different area with different constitutents was 89.7%,91.4% and 94.7%, respectively. The esterification rate for more FFA in waste oil was higher than that for more glyceride in waste oil. |

| Keywords: | biodiesel waste oil transesterification lipase immobilization |
