Abstract:
The present invention is a process for removing waxy haze from and improving the filterability of base stocks including heavy mineral oil base stocks, gas-to-liquids (GTL) and hydrodewaxed or hydroisomerized waxy feed basestocks by filtering the waxy haze causing particles out of the base stock employing a filter characterized by a high surface area of pores accessible to the haze wax particles which have particles dimensions of no more than about 5 microns.
