摘要
作为石化柴油的替代燃料,生物柴油在世界范围内得到广泛应用。生物柴油的不饱和结构决定了生物柴油在存贮过程中的氧化安定性比石化柴油要差。在氧化降解过程中生成氢过氧化物,以及可溶性聚合物等二级氧化产物,并对发动机造成不同程度的损害。添加抗氧剂是一种提高生物柴油的氧化安定性的有效方法。本文对生物柴油抗氧剂的研究现状进行了综述,并对生物柴油抗氧剂的发展趋势作了展望。
Biodiesel is widely used as an alternative fuel to petrodiesel.The unsaturated composition of biodiesel makes it more susceptible to oxidation during long-term storage than conventional petroleum-based diesel.Oxidative degradation during storage can form hydroperoxides,soluble polymers,and other secondary prod- ucts,which bring lots of damages to the engine.One promising method of increasing the resistance to oxidation of biodiesel is to add antioxidants. This review summarizes current research status and the development of effective antioxidants for treating biodiesel.Finally,the research trends of biodiesel antioxidant are also provided.
