开发木本油料植物作为生物柴油原料的研究

本文根据德国、欧盟和美国制定的生物柴油标准制定了以碘值、十六烷值和脂肪酸组成等参数作为植物油质量的评价体系。通过四条标准，即51<十六烷值<65、碘值<115、亚麻酸<12%和十八碳四烯酸<1%、碳链长度为C12-C22，对国产118种种子含油量超过30%的木本油料植物进行评估，共筛选出53种木本油料植物的种子油可作为发展生物柴油最适合的原料。其中油茶、杏、无患子、臭椿、白檀、海州常山分布广，是值得推广种植的生物柴油植物。富油大科山茶科和无患子科植物的种子油一般都适合发展生物柴油，而富油大科樟科、松科和卫矛科植物的种子油不适合作生物柴油原料。我国各省区可因地制宜选择合适的能源树种，发展生物柴油产业。

Oil-bearing trees as a source for biodiesel

Criteria had been established for the preliminary evaluation of plant species as potential biodiesel raw materials based on the major specifications of biodiesel standards of Germany, European Organization and USA. Fatty acid composition, Iodine Value (IV) and cetane number (CN) were commonly considered to predict the quality of fatty acid methyl esters of seed oils. Four criteria to screen oil-bearing trees in China were established, including: 51
