【摘要】 利用低温显微技术对添加降凝剂EVAP前后柴油中蜡的生长形态变化进行了实时观测研究,同时利用x射线衍射技术研究了加剂前后蜡晶微观结构的变化。研究表明,在柴油中添加降凝剂后,蜡的分散度、完整度、结晶度都得到了明显的提高,从而改善了柴油的低温流动性能。更多还原

【Abstract】 Low-temperature micrography technology was applied to the real-time observation of the growth conformation differences of wax crystals in diesel fuel with/without EVAP,and XRD was also performed.The results showed that with the addition of EVAP,the dispersity,integrity and crystallinity of the wax crystals in the diesel fuel were all enhanced greatly the cold flow properties of the diesel fuel were improved.更多还原
