不饱和油脂交叉易位合成生物煤油的研究

Study on Preparation Process of Bio-kerosene from Unsaturated Fat through Olefin Metathesis Reaction

研究了一种将油脂转化为一种碳数类似煤油的轻质燃油的全新方法,其合成步骤主要是:首先将富含双键的油脂与甲醇酯交换得到脂肪酸甲酯;再将甲酯与3-己烯通过交叉易位合成一些列碳数在9到16的烯烃燃料油;最后通过精馏将烯烃燃料油与饱和脂肪酸甲酯分离即得所需轻质燃油(生物煤油)。

Discuss a new way on preparation process of light fuel from unsaturated fat, the synthetic method mainly include two steps： first, Synthetize fatty acid methyl esters with grease which rich in double bond; Then, mixed the fatty acid methyl esters with 3-hexylene synthetize light fuel through olefin metathesis re- action, this light fuel carbon number from 9 to 16, similar kerosene; Last, by distillation, distill off light fuel from the mixedoil.
