Abstract

Abstract: The up to date research progress of the processing technology for lube base oils prepared from Fischer-Tropsch syncrude(mainly for Fischer-Tropsch wax)were reviewed.The review emphasized on the search and application of GTL base oils technologies for Chevron、Shell、ExxonMobil and Petro-China companies.The analysis shows that Fischer-Tropsch syncrude is composed of alkanes, the core of GTL base oil processing technology is the paraffin hydroisomerization technologies, the improved catalyst is used, the properties of GTL base oil have intermediate viscosity grade, high viscosity index, great evaporation loss and the yield reached the industrialization level.But comparing with mineral base oils it still has a lot of deficiencies.The great effort should be do to improve the performance and yield of GTL base oils through developing the new catalyst based on the characteristics of Fischer-Tropsch syncrude, also the optima? oil processing technology route should be selected.so that to realize the optimal efficiency of the Fischer-Tropsch syncrude, and provide the reference for domestic to development Fischer-Tropsch synthesis base oil processing technology.

Key words: Fischer-Tropsch syncrude, hydrogenation, GTL base oils, isomerization, catalyst

摘要： 对近年国内外以费托合成物(主要为费托蜡)为原料制成GTL基础油的加工技术研究进行了综述,着重介绍Chevron、Shell、ExxonMobil和中石油在GTL基础油加工技术的研究工作及应用情况。分析表明:费托合成物烷烃含量高,GTL基础油加工技术的核心是正构烷烃的加氢异构化技术,催化剂主要为改进的异构催化剂,所得GTL基础油黏度主要为中质黏度等级、黏度指数高、蒸发损失好,收率达到工业化水平。但与矿物基础油相比还存在很多不足,需依据费托合成物的特性,开发有针对性的催化剂,选择最佳的油品加工技术工艺路线,以便进一步提高基础油的性能和收率,实现费托合成物的最优经济性。同时为国内发展费托合成基础油加工技术提供参考。
