METHOD FOR HIGH TEMPERATURE COOLANT OIL PRODUCTION Russian patent published in 2017 - IPC C10G21/20 C10G7/06 C10M101/02

Abstract RU 2617121 C1

FIELD: chemistry.

SUBSTANCE: unconverted residue of sulfur and high-sulfur oil fuel hydrocracking is subjected to distillation in order to select fractions 350-400°C with its subsequent extraction with N-methylpyrrolidone and subsequent division to extract and raffinate solutions, N-methylpyrrolidone discharge from the raffinate and extract solutions obtain raffinate and extract - high temperature coolant oil.

EFFECT: method allows to obtain coolant oil without additional post-treatment from the available petroleum feedstock.
