| 中文摘要: |
| 通过多塔连续精馏分离工艺，实现了生物柴油（混合脂肪酸甲酯）中单酯之间的分离，获得的C16、C18单酯纯度均为96.5%以上、C20单酯纯度为86.5%以上，C16、C18、C20 3种单酯总收率为92%以上，有效地开发了生物柴油下游高附加值产品，为生物柴油产业的发展提供了有价值的参考数据和技术支撑，有利于提升行业利润。 |
| 英文摘要: |
| The separation of monoester from biodiesel (mixed fatty acid methyl ester) was realized by a process of multi-tower continuous distillation. The purities of C16 and C18 monoesters were above 965%，and the purity of C20 monoester was above 86.5%，besides, the total yield of C16, C18 and C20 monoesters was more than 92%. The downstream products of biodiesel with high additional value were developed effectively. The research provided valuable reference data and technical support for the development of biodiesel industry，and it was beneficial to improve the profit of the industry. |
