超临界流体制备生物柴油的研究进展

Research progress of biodiesel preparation by supercritical fluid techniques

着重论述了国内外超临界流体在制备生物柴油方面的研究进展。制备生物柴油的超临界流体技术是利用动植物油脂与超临界流体反应生产脂肪酸甲酯的新工艺。与传统的催化反应技术相比,超临界流体生产技术具有时间短,提纯过程简单,脂肪酸甲酯产率高,对环境友好无污染等特点。

The advances in biodiesel preparation by supercrittcal fluid techniques are reviewed at home and abroad in detail.New methods are explored for producing fatty acid methyl ester via the reaction of vegetable oils or fats with supercritical fluid.The supercritical reaction techniques are summarized and compared with the traditional chemical methods.The supercritical method requires shorter reaction time,simpler purification procedure and high recovery of fatty acid methyl ester.
