摘要
介绍了分别以H2SO4和KOH作催化剂，米糠毛油与甲醇两步反应生产生物柴油的工艺。结果表明，酯化的最优条件为：醇油摩尔比13．5：1，硫酸5．52％（油重），温度65℃，反应时间2h；酯交换的最优条件为：醇油摩尔比6：1，KOH1％（油重），温度55—65℃，反应时间90min，生物柴油转化率达99．3％。
Using H2SO4 and KOH as catalyst, crude rice bran oil and methanol were used to produce biodiesel. The results showed that the optimum reaction conditions of esterification were： molar ratio of methanol to oil 13.5：1 ,H2SO4 dosage 5.52% （ based on oil weight） ,reaction temperature 65 ℃ ,reaction time 2 h;the optimum reaction conditions of transesterification were： molar ratio of methanol to oil 6：1, KOH dosage 1% （based on oil weight）, reaction temperature 55 - 65 ℃, reaction time 90 min. The conversion rate of biodiesel was over 99.3 % under the best conditions.
