Abstract:
A process for making a lubricating base oil having a viscosity index of at least 110, comprising the steps of: combining a waxy light neutral base oil and a wax derived from pyrolyzing a plastics feed comprising polyethylene to form a blend; hydroisomerization dewaxing the blend; and recovering the lubricating base oil from an effluent from the hydroisomerization dewaxing step.
