Abstract (en)
Process to prepare two types of lubricating base oils, namely a base oil having a viscosity index of between 80-120 and a base oil having a viscosity index of greater than 120, wherein the base oils further have a saturates content of above 90 wt% and a sulphur content of below 0.03 wt% by performing a solvent extraction, a solvent dewaxing, a wax isomerisation and an oil hydrotreatment.
