In recent years biodiesel has drawn considerable amount of attention as a clean and renewable fuel. Biodiesel is produced from renewable sources such as vegetable oils and animal fat mainly through catalytic or non-catalytic transesterification method as well as supercritical method. However, as a consequence of disadvantages of these methods, the production cost increases dramatically. This article summarizes different biodiesel production methods with a focus on their advantages and disadvantages. The downstream and upstream strategies such as using waste cooking oils, application of non-edible plant oils, plant genetic engineering, using membrane separation technology for biodiesel production, separation and purification, application of crude glycerin as an energy supplement for ruminants, glycerin ultra-purification and their consequent roles in economizing the production process are fully discussed in this article.
近年来，生物柴油作为一种清洁可再生燃料引起了相当大的关注。生物柴油主要通过催化或非催化酯交换法以及超临界法，由可再生资源如植物油和动物脂肪生产而来。然而，由于这些方法的缺点，生产成本大幅增加。本文总结了不同的生物柴油生产方法，重点介绍了它们的优缺点。还充分讨论了下游和上游策略，如使用废弃食用油、应用非食用植物油、植物基因工程、使用膜分离技术进行生物柴油生产、分离和纯化、将粗甘油用作反刍动物的能量补充、甘油超纯化及其在节约生产过程中的作用。
