Mengen van Fischer-Tropsch-basisolien met een lage viscositeit voor het produceren van basissmeerolien van hoge kwaliteit.

摘要

A process for preparing Fischer-Tropsch derived lubricating base oils by blending a Fischer-Tropsch distillate fraction having a viscosity of 2 or greater but less than 3 cSt at 100 degrees C. with at least one additional Fischer-Tropsch derived distillate fraction having a viscosity of greater than 3.8 cSt at 100 degrees C.; lubricating base oil compositions having a viscosity between about 3 and about 10 cSt at 100 degrees C. and a TGA Noack volatility of less than about 35 weight percent; and finished lubricants using the aforesaid lubricating base oils.
