| 中文摘要: |
| 以介孔材料MPS为载体将脂肪酶固定化,以碳酸二甲酯为酰基受体,对固定化酶催化碳酸二甲酯进行了反应路径(原料油)、反应条件(反应温度、碳酸二甲酯的用量、加水量)的优化,在最优的条件下对实验过程中所用的固定化酶进行重复使用性的考察。实验结果表明,不同种油与碳酸二甲酯反应在固定化酶的催化下制备生物柴油的产率,麻疯树油最高；该反应体系的最佳反应条件是：碳酸二甲酯的浓度为16mL/g、不加水、温度为50oC、反应时间24h。该条件下生物柴油得率最高,达81.6%。 |
| 英文摘要: |
| In this study, biodiesel was synthesized by transesterification of oil and dim ethyl carbonate catalyzed by immobilized lipase (CLL@MPS) at various conditions. Experimental investigation of the kind of oil revealed that the conversion of biodiesel was maximized with jatropha oil. For the enzymatic production of biodiesel, the optimum conditions were the amount of dim ethyl carbonate (16mL/g), reaction temperature (50?C), reaction time (24h) and the amount of water added (no water added). The yield of biodiesel finally reached 81.6% under the optimum condition. |
