摘要： 很高黏度指数润滑油是调配高级内燃机油的重要基础原料,目前国内生产厂家较少，产量也很低，而超高黏度指数润滑油国内还未生产。以含油蜡膏为原料，采用以异构脱蜡催化剂为核心的全加氢工艺和酮苯脱蜡工艺组合，研制超高黏度指数润滑油基础油。结果表明：采用该组合工艺可以生产出符合UHVI150，UHVIS150，UHVIW150指标的润滑油基础油，产品黏度指数达146以上。
Abstract: Lubricating base oils with high viscosity index are the important basic raw materials for production of high-grade internal combustion engine oil. At present a few domestic manufacturers produce them with low output, and No domestic plant produces the ultra-high viscosity index base oils. The preparation of ultra-high viscosity index lube base oils was studied. The results indicate that when oily wax is used as feed, the lube base oils with viscosity index higher than 146, which meet the requirements of UVHVI150, UHVIS150 and UHVIW150, can be produced by combined technology of iso-hydrodewaxing and ketone-benzol dewaxing process.
