| 摘 要： | 用化学法生产生物柴油时常规工艺会产生大量的废水,随着国家对环境保护工作的重视,废水处理量大是制约企业生产与发展的一大技术瓶颈。介绍了干法预处理及分酸二步法生产生物柴油的新工艺,主要为原料油经过干法脱杂、油酸分离、分别进行酯化与酯交换、酸碱平衡等工艺过程生产出合格生物柴油。新工艺节能、环保,大大减少了废水排放量。

| Abstract: | There is a large amount of waste water in the conventional process of production of biodiesel by chemical method. With the attention of the state to environmental protection, large waste water treatment is a major bottleneck restricting the production and development of enterprises. A new production process of biodiesel by dry process pretreatment and acid separation two-step method was introduced. Qualified biodiesel was produced by removing impurities by dry method, separation of oil and acid, esterification and transesterification respectively, acid-base balance, etc. The new process had the advantages of energy saving, environmental protection and great reduction of discharge of waste water. |

| Keywords: | biodiesel dry process pretreatment acid separation two-step method discharge of waste water |
