【摘要】 在反应蒸馏装置中对植物油与甲醇的酯交换反应合成生物柴油进行了研究。结果表明,此工艺具有反应速度快、平衡转化率和选择性高、甘油沉降速度快等特点。与流行的两级甚至三级酯交换反应技术相比,仅通过一段酯交换反应就能达到相同的反应效果。更多还原

【Abstract】 Continuous-flow reactive distillation technique was used to prepare biodiesel fuel from vegetable oil.The results showed that said technique exhibited faster reaction rate,higher conversion,better selectivity and easier separation of glycerol as compared with the conventional CSTR technique.As a result,to reach the same conversion a single stage transesterification was needed instead of two or three reaction stages.更多还原
