摘　　要：考察了异养小球藻原料直接制备生物柴油的主要因素,并建立了直接酯交换的最佳工艺条件。通过单因素试验考察了硫酸添加量、含水量、乙醇添加量、反应温度、反应时间对酯化反应过程中粗生物柴油产率的影响,并采用正交试验对反应条件进行优化。得出最佳工艺条件为:硫酸添加量(硫酸与原料质量比)6∶1,含水量10%,乙醇添加量(乙醇与原料质量比)11∶1,反应温度90℃,反应时间3 h。在最佳工艺条件下,粗生物柴油产率可达59.72%,所获得生物柴油品质优良。The main influencing factors of direct preparation of biodiesel using Chlorella as raw materials were studied, and the optimal conditions of direct esterification were established. Through single factor experiment, the effects of dosage of sulfuric acid, water content, dosage of ethanol, reaction temperature and reaction time on the yield of crude biodiesel in the process of esterification were studied, and the reaction conditions were optimized by orthogonal experiment as follows ： dosage of sulfuric acid （ mass ratio of sulfuric acid to raw material） 6： 1, water content 10%, dosage of ethanol （mass ratio of ethanol to raw material ） 11 ： 1, reaction temperature 90 ℃ and reaction time 3 h. Under the optimal conditions, the yield of crude biodiesel reached 59.72%, and the quality of biodiesel was good.
