| 摘 要： | 为充分利用高酸值米糠毛油，将其脱酸成生物柴油原料。采用酯化脱酸方法，通过对多种酯化脱酸催化剂的比较，结果表明氧化锌具有较强的催化活性。氧化锌作为米糠油酯化脱酸的催化剂，分别考察了甘油添加量、催化剂添加量、反应温度、反应时间对酯化脱酸的影响。得到了以下较优工艺参数：真空度为0.1 MPa，甘油添加量为理论甘油量1.044 g，催化剂添加量为油质量的0.1%，反应温度200℃，反应时间6 h。在此优化条件下，米糠油的酸值从38.14 mg/g降至5.17 mg/g，满足了作为生物柴油生产原料的要求。

| Abstract: | To take full advantage of the high-acid rice bran crude oil,the authors carried out experiments to deacidify high-acid rice bran crude oil by esterification for the raw material of biodiesel.In this paper,the esterifying catalytic activity of several catalysts and the influence of glycerol dosage,catalyst dosage,reaction temperature and reaction time on deacidification were investigated.The results showed that ZnO had a strong catalytic activity.The optimum conditions of esterification with ZnO were the the... |
