摘　　要：生物柴油是典型的“绿色可再生能源”。然而生物柴油的凝点一般在0℃时,其低温结晶和凝胶化限制了生物柴油在低温时的应用。生物柴油低温流动性能主要与生物柴油中的饱和脂肪酸甲酯的含量和分布有关,还与脂肪酸酯的支链程度有关。综述了改善生物柴油低温流动性的方法,降凝剂的作用机理及生物柴油降凝剂的研究、应用及发展前景。Bio-diesel is an alternative biodegradable diesel fuel. However, the pour point of the Bio-diesel is about 0℃, as a result that the freezing and gelling of many bio-diesel formulations are limiting their applications. The low-temperature fluidity of the bio-diesel fuel depended on the content and distribution of the Saturated fatty acid methyl esters in the fuel. It also depends on the degree of the branched-chain esters. In this paper, the methods to improve the low-temperature fluidity, the mechanisms of the pour point depressant and the research, application , development of pour point depressant were reviewed.
