Abstract: A study of extraction technology and equipment for the mass production of bio-diesel from cottonseed oil via transesterification was made. Under the optimal condition after reacting with methanol for 50 min, the maximum methyl ester yield was 99%. The bio-diesel fuel obtained from this technology had a similar specification with diesel fuel. The burning index of this bio-diesel fuel was similar with or even better than diesel fuel and the emission met Europe II standard.

摘要： 采用棉籽油为原料连续化生产生物柴油，研究了工艺及设备的设计。由棉籽油与甲醇在催化剂NaOH存在下由酯交换反应制得生物柴油。在优化条件下反应50 min，转化率达到99%。生产的生物柴油，各项指标与天然柴油相似。其各项燃烧指标优于或与普通柴油相仿，满足欧洲Ⅱ排放标准。
