Abstract: Homogeneouse and heterogeneous catalysts for the catalytic transesterification of biodiesel were summarized in the paper，including the comparison of different kinds of catalysts and their applications. It was found that solid catalysts would meet the requirement of green production of biodiesel，with the advantages of solid acid catalyst catalyzing transesterification of oils containing water and free fatty acid.

摘要： 催化酯交换是制备生物柴油的一个重要方法。本文综述了均相催化和非均相催化、酸性催化和碱性催化、固体酸和固体碱催化的研究进展，并针对每类催化剂的特性和应用范围进行比较，得出固体酸和固体碱催化符合绿色生产生物柴油的要求，是未来发展的方向。特别是固体酸在催化含有水分和游离酸的油脂酯交换方面具有独特的优势，需要进一步研究和开发。
