EVA类降凝剂对生物柴油低温流动性的作用机理
Mechanism of EVA pour point depressant in biodiesel
摘要
Abstract
The effect of ethylene-vinyl acetate (EVA) pour point depressant was determined on biodiesel by pre-screening. DSC, low temperature XRD and polarizing optical microscope were used to study the mechanism of ethylene-vinyl acetate pour point depressant (PPD) on soybean biodiesel. The results show that: PPD does not reduce the amount of wax crystals in biodiesel. Eutectic effect occurs between PPD and fatty acid methyl ester. PPD changes the growth habits and gathering way of the wax crystals. The wax crystals appear almost spherical, disperse better, not easy to crosslink between wax crystals and reduce the cold filter plugging point (CFPP) and solidification point (SP) of biodiesel.关键词
