| 摘 要： | 针对新疆地产柴油蜡含量较高的特点,以游离基聚合法合成了富马酸双链混合酯和醋酸乙烯酯共聚物型[P(DBF-VA)]柴油低温流动改进剂,利用正交实验研究了单体配比,引发剂用量,溶剂用量,聚合温度对聚合物降冷滤效果的影响。共聚物用IR进行表征,利用XRD初步探讨了该降凝剂的降凝机理。结果表明:该剂能使吐哈—10~#、0~#柴油冷滤点降低10℃和7℃;使独山子0~#柴油冷滤点下降12℃;使石化0~#柴油冷滤点下降8℃;使克拉玛依0~#柴油的冷滤点下降8℃。

| Abstract: | Dibehenyl fumarate-vinyl acetate copolymer [P(DBF-VA)] was obtained by free radical co- polymerization as low temperature diesel flowing improver for the Xinjiang high wax content diesel. The influencing factors such as monomer ratio,mass fraction of initiator and solvent and reaction tem- perature on cold filter plugging point (CFPP) depressing effects were investigated by orthogonally de- signed experiments.The structure of the copolymer was confirmed by IR.The functions of the syn- thesized low temperature flow improver was explored using XRD.The results showed that DBF-VA lowered the CFPP of the—10~# and 0~# diesel fuel from Tuha by 10℃and 7℃,respectively,lowered the CFPP of the 0~# diesel fuel from Dushazi by 12℃,lowered the CFPP of the 0~# diesel fuel from Wushiha by 8℃,and lowered the CFPP of the 0~# diesel fuel from Kelamay by 8℃. |
