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15.1MPa、反应温度330℃、体积空速1.4h-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。
Using hydroisomerization catalyst PIC-812 developed by the Petrochemical Research In- stitute 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.
