摘要
近几年美国和欧洲车用润滑剂趋于发展较低粘度的多级油。在过去的几年中，欧洲汽车制造公司也在油品消耗、轴承保护和剪切安定性方面，对规格认可从严掌握。其结果是，传统的溶剂精制矿油已不能满足这些要求最严的规格。因此，对具有优良挥发性和低温性能的超高粘度指数基础油的需求正在增长。目前能满足这种要求的石蜡基基础油主要有三种，即聚α-烯烃（PAO）、异构化蜡和加氢裂化（HC）油。本文对用催化加氢工艺生产润滑油基础油进展进行综述。
Current trends in automotive lubricants in U. S. and Europe indicate a growing demand for lower viscosity multigrade oil. The demand for very high VI base oils has arisen. There are cur rently three paraffinic base oils which can fulfill this role:po1yalpholefins(PAO),wax isomerised and hydrocracked (HC)oils. In this paper we reviewed the advances in lUbe base oil manufacture by catalytic hydroprocessing
