| Abstract: | In accordance with the features of intennediate crude oils, the dependency of viscosity index and oxidation stability on the lube oil composition were described based on their structures and constitution. Several measures to improve the qualities of lubricant base oils including blending, denitrogenation, mild hydrotreating etc. were also discussed. Among them, the mild hydrotreating process is capable of both enhancing viscosity index and improving oxidation stability of the oils. |
