Abstract

See full text

Methods are provided for producing Group II/III lubricant base oil products where at least a portion of the feedstock for forming the lubricant base oil product is a solvent extract fraction from a Group I lubricant production facility. This can increase the overall volume of feedstock available for production of Group II/III lubricant base oils by using a lower value stream (Group I solvent extract) as a portion of the feedstock. The solvent extract fraction can be added to a full range lubricant feedstock or to a portion of a lubricant feedstock, such as adding an extract fraction to a higher viscosity portion (such as a heavy neutral portion) of a feedstock for lubricant production, while a lower viscosity portion (such as a light neutral portion) is processed without addition of an extract fraction.
