摘要/Abstract

摘要： 富含长链正构烷烃的石蜡基减四线VGO是生产重质高品质API III 类润滑油基础油的优质原料。然而过高的蜡含量在提高基础油黏度指数的同时，也造成了基础油产品浊点的升高。针对这一技术问题，中国石油石油化工研究院从分子筛形貌控制、催化剂制备技术入手，开发出了新一代低浊点润滑油加氢异构催化剂PHI-01，解决了重质基础油因黏度指数升高而带来的浊点与收率的平衡问题。该催化剂在中国石油大庆炼化分公司200 kt/a 润滑油加氢异构装置的工业应用结果表明，加工大庆减四线加氢精制油时，液体收率为96%，10 cSt基础油产品收率为68.1%，其浊点为－7 ℃，达到低于－5 ℃的指标要求。

Abstract: VGO, which is rich in long chain n-alkanes, is a high-quality raw material for producing heavy and high-quality API III lubricating base oil. However, the high wax content not only increases the viscosity index of lubricating base oil, but also increases the cloud point of base oil products. In view of this problem, PetroChina Petrochemical Research Institute(PRI) developed a new kind of nano-scale zeolite with short axis morphology and very good performance in n-alkane hydroisomerization process. Base on this zeolite, a new generation of lubricating oil hydroisomerization catalyst PHI-01 was developed, which solves the problem of balance between cloud point and yield caused by the increase of viscosity index of heavy base oil. The commercial application of the catalyst in 200 kt/a lube oil hydroisomerization unit of Daqing Refining and Chemical Company of PetroChina showed that the liquid yield was 96%, the yield of 10 cSt base oil was 68.1%, and the cloud point was －7 ℃, which was lower thanthe requirement of －5 ℃.

Key words: lubricating base oil, cloud point, viscosity index, base oil yield
