摘要:

以焦化煤油馏分为原料,采用络合萃取法富集原料中的线性α?烯烃,通过齐聚反应合成高黏度聚α?烯烃(PAO)基础油。考察了温度、时间、催化剂质量分数等工艺条件对PAO性质的影响,同时测定了100 ℃运动黏度、黏度指数及PAO收率。在催化剂质量分数为6%、聚合反应温度为25 ℃、聚合反应时间为8.0 h、加聚反应温度为80 ℃、加聚反应时间为2.0 h的工艺条件下,反应效果最佳;PAO在100 ℃时的运动黏度为43.54 mm2/s,黏度指数为163,凝点为-50 ℃,闪点为291 ℃,收率为85.48%。对比PAO40标准,得到的产品为高黏度润滑油基础油。

Abstract:

The coking kerosene fraction was used as the raw material for the experiment. The linear α?olefins in the raw oil were enriched by complex extraction method, and the high viscosity poly α?olefin base oil (PAO) was synthesized by oligomerization. The effects of temperature, time and catalyst dosage on the properties of PAO were investigated. The kinematic viscosity, viscosity index and PAO yield rate at 100 ℃ were determined. Under the optimum process conditions of catalyst mass fraction of 6%, polymerization temperature of 25 °C, polymerization time of 8.0 h, addition polymerization temperature of 80 °C and addition polymerization time of 2.0 h, the reaction effect is the best: The kinematic viscosity of PAO at 100 ℃ is 43.54 mm2/s, the viscosit index is 163, the freezing point is -50 ℃, and the flash point is 291 ℃. The yield is 85.48%. Compared with the PAO40 standard, the obtained product is a high viscosity lube base oil.
