Abstract:

Although bio-diesel shows great promise as a renewable，alternate fuel，it is important to note that there are still disadvantages associated with its production and use. In this paper，the research advances by thermal chemical conversion，including thermal cracking and catalytic cracking processes for biofuel production are presented. The main problems are mentioned and the prospect of this research field is presented. Different catalysts used in catalytic cracking are compared and discussed. The catalyst with good selectivity for hydrocarbon products is a research priority.

摘要：

生物柴油是重要的可再生液体燃料，但其在制备方法及自身燃料性质上仍存在一定的缺陷。近年来出现的热化学方法提供了较有前景的解决方案。本文综述了油脂热化学转化制备生物质柴油新方法。重点介绍了直接热解、催化热裂解两种转化方式的现状及特点，并探讨了热化学转化方法还存在的问题。对催化裂解过程所用不同功能催化剂的性能及特点作了详细的介绍，指出了目前油脂裂解过程催化剂的研究方向。
