Biodiesel made from renewable feedstock can be considered as a renewable and sustainable alternative to fossil fuels. This review briefly covers the historical background on biodiesel and discusses the various renewable feedstock sources for biodiesel production. It also emphasizes the importance of not only the feedstock quality but also on biodiesel quality that satisfies the ASTM D6751 and EN 1421 standards. In addition, the review describes various methods for biodiesel production with major thrust on transesterification, which is the key process. It also highlights the use of different types of catalysts including acidic, basic, bi-functional, and enzymes in the transesterification reaction. The review concludes by emphasizing the importance of pursuing further research and development to address the challenges in developing low cost and eco-friendly processes for biodiesel production.
由可再生原料制成的生物柴油可被视为化石燃料的一种可再生且可持续的替代品。本综述简要介绍了生物柴油的历史背景，并讨论了用于生物柴油生产的各种可再生原料来源。它还强调了不仅原料质量的重要性，而且满足美国材料与试验协会D6751和欧洲标准EN 1421的生物柴油质量的重要性。此外，该综述描述了生物柴油生产的各种方法，重点是酯交换反应，这是关键过程。它还突出了在酯交换反应中使用不同类型的催化剂，包括酸性、碱性、双功能和酶催化剂。综述最后强调了开展进一步研发以应对生物柴油低成本和环保生产工艺开发中挑战的重要性。
