摘要
生物柴油是一种可再生的生物能源,近年来得到广泛关注。固体酸催化剂可同时催化油脂和脂肪酸制备生物柴油,同时还具有环境友好、易于和产物分离等优点。本文综述了沸石分子筛、杂多酸、离子交换树脂、固体超强酸等固体酸在催化合成生物柴油方面的研究进展。
Biodiesel is a kind of renewable bio-energy and has received much attention in recent years.Both triglycerides(TGs) and free fatty acids(FFAs) could be used to produce biodiesel using heterogeneous acids as catalysts,which are environmental friendly and could be easily separated from products.In this paper,the utilization of solid acid,such as zeolite,heteropolyacid,ion-exchange resins,super solid acid and so on is reviewed for biodiesel production.
