摘要
生物柴油是以动植物油脂为原料制备的石油替代燃料,由一系列长链脂肪酸甲酯组成,具有环保、可再生等优点。酯交换法制备生物柴油研究的最多,包括酸碱、固体碱、生物酶、有机碱、离子液体作催化剂的酯交换以及无催化剂的超临界甲醇法酯交换。介绍了各种方法的优缺点,提出了今后的发展方向。
Biodiesel takes vegetable oils and fats as raw material and is a substitution of petroleum. It consists of a series of long chains fatty acid methyl esters and can be regenerated as well as many advantages for environment. There were many transesterification methods,including the catalyzation methods and non-catalyzation method. The catalysts in the former were alkali, solid alkali, biological enzyme, organic alkali, ion liquids, and so on. The latter was supercritical ester exchange. The advantages and disadvantages of each method were analyzed, and the prediction of biodiesel development was proposed.
