| 摘 要： | 探讨了叔丁醇体系中脂肪酶Novozyme 435催化动物油脂制备生物柴油的新工艺。用猪油做原料，醇油摩尔比为5∶1， Novozyme 435用量3％（质量分数），叔丁醇用量40％（体积分数），50℃下240r/min反应24 h，生物柴油得率为95.2%。酶重复使用10批次后生物柴油得率仍保持在90%以上，结果表明新工艺条件下猪油可以有效转化为生物柴油，且脂肪酶能保持良好的稳定性。

| Abstract: | A new method for biodiesel production from lard involving catalysis by immobilized lipase Novozyme 435 has been developed. The optimal parameters were found to be 5∶1 molar ratio of methanol/oil, 3% (mass fraction) Novozyme 435, 40% (volume fraction) tert-butanol, and a reaction temperature of 50℃. The results showed that after 24 hours, the highest yield of methyl ester obtained was 95.2% . When the lipase was repeatedly used for 10 cycles under the optimal conditions,yields of methyl esters of over 90% were obtained. This indicates that lard canbe effectively converted into biodiesel and that lipase exhibits good stabilityunder the conditions employed. |
