Process for hydrodesulfurizing and hydrotreating lubricating oils from sulfur-containing stock

摘要

An improved process for producing lubricating oils from a lubricating oil stock containing at least 2.0 weight percent sulfur by subjecting such stock to hydrodesulfurization so as to obtain a product containing a maximum of 1.0 weight percent sulfur. The desulfurized effluent is then subjected to hydrotreating.
