Research Progress of Rare Earth Doped SO_(4)^(2-)/M_(x)O_(y) Solid Acid Catalysts for Biodiesel Production

生物柴油是一种生物可降解、可再生、无毒优质的清洁燃料。目前,采用掺杂稀土改性多相SO_(4)^(2-)/M_(x)O_(y)型固体酸催化剂制备生物柴油的方法引起学者广泛关注。本文综述了该类催化剂的几种常用制备方法及在生物柴油制备中的研究进展。最后预测了该类催化剂在生物柴油工艺中的发展前景。

Biodiesel is a kind of biodegradable, renewable, non-toxic and high quality clean fuel. At present, the preparation method of biodiesel using the doped rare earth modified polyphase SO_(4)^(2-)/M_(x)O_(y) solid acid catalyst has attracted wide attention of scholars. In this paper, several common preparation methods of this kind of catalyst and the research progress in biodiesel preparation are reviewed. At last, the development prospect of this kind of catalyst in biodiesel process is predicted.
