Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for forming a lubricant product, comprising: providing a feedstock having a T5 boiling point of at least 600° F. (343° C.) and a T95 boiling point of 1150° F. (621° C.) or less; combining the feedstock with an extract fraction from a solvent extraction process used to produce a Group I base stock to form a combined feed wherein from 5 vol % to 40 vol % of the combined feed is the extract fraction, the extract fraction having a total aromatics cont…
