摘要：
A process to make a light base oil fraction having a wt % Noack volatility between 0 and 100 and additionally less than a Noack Volatility Factor (NVF), wherein the Noack Volatility Factor is defined by the equation: 900×(Kinematic Viscosity at 100° C.)−2.8−15. The process comprises hydroisomerization dewaxing a waxy feed in a series of two or more reactors, and recovering the light base oil fraction having a low wt % Noack volatility.
