摘要
当前全球石油需求不断增长与化石能源日渐枯竭的矛盾日益突出,能源供给形势紧张,国际市场原油价格大幅震荡,加之化石能源大规模使用引起的环境问题已成为近年来普遍关注的两大焦点问题（Karmakar et al.,2010;楼狄明等,2011）。因此,能源的多元化、可再生化和清洁化已成为人类社会发展的必然选择,开发生物质能源是解决全球能源危机的方向之一。生物柴油,是指利用各类动植物油脂为原料,与甲醇或乙醇等醇类物质经过酯交换反应,使其最终变成可供内燃机使用的一种燃料,具有优良的环保性、低温起动性、润滑性及可再生性,是理想的石化柴油补充燃料,对缓解当前巨大的能源和环境压力具有很大作用（林水富等,2010）。
In this paper, we studied oil contents of the fruits or seed kernels, fatty acid composition and biodiesel fuel properties of four major potential woody biodiesel plant species （Pistacia chinensis, Xanthoceras sorbifolia, Armeniaca sibirica and Armeniaca mandshurica） in the northern region of China. The evaluated biodiesel fuel properties include the density, kinematic viscosity, cetane number, cold filter plugging point and oxidation stability. The results showed that fruits or seed kernels of the four woody plants had high oil content （35. 0%, 58. 9%, 50. 2% and 47. 2%, respectively）. The Fatty acid composition of their oils accorded with the ideal biodiesel feedstock standard. The four woody plants had good biodiesel fuel properties, especially the cetane number that was conformed to ASTM D6751 standards （P. chinensis met the specification from the EN 14214 biodiesel standard） , and the cold fluidity of A. sibirica and A. mandshurica were excellent （cold filter plugging point of - 14 ℃ ）. In conclusion, the four woody biodiesel plants have been identified as the promising biodiesel feedstock, which result would provide references for the exploitation and utilization of biodiesel plants in the northern region of China.
