生物柴油降凝机理的研究进展

生物柴油是可再生清洁燃料,能够减缓人类对石化柴油的依赖,然而生物柴油凝固点和粘度相对较高,低温流动性较差,冬季低温环境下结晶体易堵塞发动机管道和过滤器,使发动机无法正常工作。主要综述了生物柴油的性质、特点、降凝剂的作用机理及其研究方法。并对生物柴油的前景做了展望。

Research Progress on Pour Point Depressant Mechanism of Biodiesel at Low Temperatures

Biodiesel is a renewable clean fuel and can reduce dependence on petrochemical diesel,however biodiesel has relatively high freezing point and viscosity and poor low temperature fluidity.In winter,under the low temperature environment the biodiesel crystal is easy to jam engine pipe and filter,making the engine can't work normally.This paper summarizes the nature and characteristics of biodiesel,pour point depressant action mechanism and its research methods.And it also describes prospects of biodiesel.
