In this study, Xanthium sibiricum Patr oil, a non-edible oil, was investigated for the first time to produce biodiesel. X. sibiricum Patr has very good environmental adaptability and thus has plenty of wild resources. Its seed has a high oil content (42.34%) which gives potential annual output of 100,000 tons just in China. And the oil acid value is pretty low (1.38 mg KOH/g). Under the optimal conditions, the FAME content and yield of X. sibiricum biodiesel were 98.7 wt.% and 92.0%, respectively. The properties of the biodiesel product were tested and most properties were in accordance with EN 14214-08, ASTM D6751-10 and GB/T 20828-07 standards, except cetane number and oxidative stability. The results indicated that X. sibiricum Patr is a promising species as a biodiesel feedstock in China.
本研究首次探索利用苍耳籽油生产生物柴油。苍耳子具有极好的环境适应性，因此拥有丰富的野生资源。其种子含油率高（42.34%），仅在中国就有潜在的年产 10 万吨的产量。且其酸值较低（1.38mgKOH/g）。在最佳条件下，苍耳子生物柴油的甲酯含量和得率分别为 98.7wt.%和 92.0%。对生物柴油产品的性能进行了测试，除十六烷值和氧化稳定性外，大多数性能均符合 EN 14214-08、ASTM D6751-10 和 GB/T 20828-07 标准。结果表明，苍耳子是中国有前途的生物柴油原料。
