Abstract

Methods are provided for upgrading disadvantaged feeds for use in lubricant base stock production. A disadvantaged feed can be upgraded by hydroprocessing the feed to form a hydroprocessed bottoms fraction. The hydroprocessed bottoms fraction can then be used as a feed for forming Group I and/or Group II lubricant base stocks, optionally in combination with a conventional feed for lubricant production. The remaining portions of the hydroprocessing effluent can optionally be used for FCC processing and/or for other conventional applications of naphtha and distillate fractions.
