摘要: 采用中国石油石油化工研究院开发的PIC-812异构脱蜡催化剂对中间基减四线馏分油进行加氢精制-异构脱蜡-补充精制三段加氢工艺试验。结果表明,在异构脱蜡段氢分压15.1 MPa、反应温度330 ℃、体积空速1.4 h-1、氢油体积比500:1的条件下,经过加氢精制-异构脱蜡-补充精制评价后获得HVIH 6基础油的倾点—15 ℃、黏度指数101、收率52.58%,验证了采用中间基原料生产高档润滑油的可行性。

Abstract: Using hydroisomerization catalyst PIC-812 developed by the Petrochemical Research Institute of CNPC, high grade API Ⅱ base oils were prepared by hydrofining-hydroisomerization-hydrofinishing technology from vacuum gas oil of intermediate base crude oil. The results show that the optimized operating conditions for isodewaxing are: hydrogen partial pressure of 15.1 MPa, reaction temperature of 330 ℃, LHSV of 1.4 h-1 and hydrogen to oil volume ratio of 500. The produced HVIH 6 base oil has a pour point of -15 ℃ with a viscosity index of 101 and the yield is 52.58%. It is concluded that high-grade lube base oils can be produced from intermediate VGOs.

Key words: intermediate base crude, hydroisodewaxing, catalyst, lube base oil
