摘要
考察了十八仲胺衍生物改善高含蜡柴油低温流动性的作用规律。结果表明 ,仲胺衍生物主要是通过增溶柴油中的长链正构烷烃 ,使浊点、冷滤点降低 ,从而改善柴油低温性能。仲胺衍生物与T180 4流动改进剂 (乙烯 醋酸乙烯酯聚合物 )复合可以改善蜡晶的分散性能 。
Octadecyl secondary amine derivatives can influence the cold flow ability of waxy diesel. The secondary amine derivatives can improve the low temperature properties of diesel, lowering its cloud point and cold filter plugging point, mainly through increasing the solution of long chain normal paraffin in diesel. The combination of very low amount of secondary amine with flow improver T1804 can enhance the dispersion of wax crystals, and help reducing the cold filter points.
