摘要
研究了在高压釜中碱催化作用下制备生物柴油的最优工艺条件,考察了条件因素对反应的影响,讨论了在最佳条件下甲醇中的含水量对酯交换转化率的影响。实验结果表明,催化剂用量为菜籽油质量的1.0%,醇油摩尔比为7∶1,反应温度为50℃,反应时间为100 min为优化反应条件,甲醇的含水量与转化率呈线性关系,含水量越高,酯转化率越低。
Bio-diesel has been synthesized from vegetable seeds oil by transesterification with methanol under the catalyzer of KOH in the pressure kettle.The effects of reaction conditions has been studied.The suitable reaction conditions have been studied:the catalyst quantity is 1.0% of the vegetable seeds oil with 7∶1 of the molar ratio of methanol to oil,at 50℃ for 100 min.It has been proved that the water content in the system has the linear relationship with the transesterification rate,the less water content is,the higher conversion rate of transesterification is.
