Lubricant base oil blend having low wt% Noack volatility

Lubricant base oil blend having low wt% Noack volatility

A lubricant base oil blend having a wt% Noack volatility less than 29, comprising a) a light base oil fraction having a kinematic viscosity at 100°C between 1.5 and 3.6, and a wt% Noack volatility both between 0 and 100 and less than a Noack Volatility Factor, and b) a petroleum-derived base oil fra...

Zusammenfassung:A lubricant base oil blend having a wt% Noack volatility less than 29, comprising a) a light base oil fraction having a kinematic viscosity at 100°C between 1.5 and 3.6, and a wt% Noack volatility both between 0 and 100 and less than a Noack Volatility Factor, and b) a petroleum-derived base oil fraction. A process to make the lubricant base oil blend having a wt% Noack volatility less than 29. Also, a pour point depressed lubricant base oil blend having a Brookfield viscosity at -40°C of less than 18,000 cP, comprising the light base oil fraction, a petroleum- derived base oil fraction, and a pour point depressant.
