| 基于酯交换法研制一种多功能一体化的制备装置，用以小地域范围内地沟油的再生利用得到纯净高质量的地沟油生物柴油。结果表明：该装置区域化制备地沟油生物柴油最佳反应条件为反应温度65?℃、反应时间120 min、醇油摩尔比8∶?1、催化剂用量0.75%、搅拌速率250 r/min，此时地沟油生物柴油产率达到最大值97.3%；地沟油生物柴油的浊点、冷滤点、倾点分别为6、5?℃和 4?℃，氧化安定性、闪点、酸值（KOH）、十六烷值、密度、运动黏度分别为4.8 h、153?℃、0.37 mg/g、59、888.9 g/cm3和4.06 mm2/s，除氧化安定性外，其余各项指标均符合EN14112和ASTM D6751标准。该实验装置的各个反应装置依次通过管道和动力输送装置一体化连接，多道工序顺序结合得到生物柴油，具有高效便捷、易操作、占地小等优势。 |
| 英文摘要: |
| A multifunctional integrated biodiesel reactor was developed for the regional production of high-quality biodiesel from swill-cooked dirty oil using the transesterification reaction. The results showed that the optimal reaction conditions of the multifunctional integrated biodiesel reactor were obtained as follows: reaction temperature 65?℃, reaction time 120 min, catalyst dosage 0.75%, molar ratio of methanol to oil 8∶?1 and stirring speed 250 r/min. Under these conditions, the yield of biodiesel was the highest, achieving 97.3%. The cloud point, cold filter plugging point and pour point of the prepared swill-cooked dirty oil biodiesel were 6, 5?℃ and 4?℃, respectively. The oxidation stability, flash point, acid value, cetane number, density and kinematic viscosity were 4.8 h, 153?℃, 0.37 mgKOH/g, 59, 888.9 g/cm3 and 4.06 mm2/s, respectively. Except for the oxidation stability, other indexes of the prepared biodiesel satisfied the standards EN14112 and ASTM D6751. The various reaction devices of the experimental reactor were connected in turn via pipelines and power transmission devices, which had the advantages of high efficiency, simplicity, convenient operation and less occupied area. |
