PRODUCTION OF BASE OIL FOR LUBRICANTS Russian patent published in 2014 - IPC C10G67/04 C10G45/58

Abstract RU 2519747 C2

FIELD: process engineering.

SUBSTANCE: invention relates to production of bas oil for lubricants. Base oil for lubricants is produced at first stage whereat stock oil containing normal paraffins C₂₀ or higher is subjected to isomerisation so that content of normal paraffins C₂₀ or higher makes 6-20 wt % of total mass of hydrocarbons C₂₀ or higher in produced reaction product. Lubing oil fraction including hydrocarbons C₂₀ or higher is separated at second stage from first stage reaction products. Lubing oil fraction produced at second stage is separated at third stage to dewaxed oil and paraffin by dewaxing by solvent. Note here that dewaxed oil is used as base oil or subjected to purification by solvent and/or to hydrofining to produce base oil for lubricants.

EFFECT: higher thermal-viscosity properties of base oil.
