能源植物乌桕在生物柴油生产中作用的研究进展

Effect of Sapium sebiferum(L.) Roxb.in the Production of Bio-diesel

能源植物在生物质能源的生产中起着重要作用。生物柴油本质上是长链脂肪酸甲酯,工业上多通过酯交换反应进行生产。乌桕作为在我国广泛分布的油料树种,其种子油脂含量高达40%左右,是生产生物柴油的重要原料。综述了能源植物乌桕与生产生物柴油相关的皮油和梓油的提取工艺、用于催化乌桕油生产生物柴油的催化剂、乌桕油及种子中脂肪酸组成等方面研究的最新进展,并对生物柴油生产的重要方面进行了展望。

Energy plants play an important role in the production of biomass energy.Bio-diesel is long-chain fattyacid methyl ester,which can be produced by transesterification in industry.Sapium sebiferum（L.） Roxb.is a kind of oil tree and distribute widely in China,whose oil content in seed reached about 40%,therefore,it is an important material to produce bio-diesel.The advances of extraction techniques for vegetable tallow and stillingia oil,the catalyst used for the conversion of Sapium sebiferum（L.） Roxb.to bio-diesel and the constitution of fatty acid in Sapium sebiferum（L.） Roxb.and its seed were summarized,and the important aspects of the production of bio-diesel were prospected.
