摘要：
A process for preparing high VI lubricating oil basestocks comprising hydrotreating, hydrodewaxing and optionally hydrofinishing. The hydrotreated feedstock is hydrodewaxed using a dewaxing catalyst that has been selectively activated by oxygenate treatment. The hydrodewaxed product may then be hydrofinished.
