Abstract:
A process for preparing a base oil from a waxy hydrocarbon feedstock is provided. The process comprises passing the hydrocarbon feedstock to a distillation column prior to dewaxing in order to recover a heavy wax cut. The heavy wax is then hydrocracked to lower boiling compounds which can be better isomerized to a base oil with an acceptable cloud point. The base oil yield is also increased.
