More Information
Summary:The present disclosure provides a method of preparing a lube base oil. The method comprises (a) providing a feed stream, (b) separating the feed stream into at least two fraction streams comprising a first fraction stream and a second fraction stream, and (c) before or after the separating of the feed stream, introducing the feed stream or at least two fraction streams into a first and second hydro-processing treatments to produce at least two product streams, and the first product stream has a higher viscosity index (VI) than the second product stream. The present disclosure also provides a lube base oil and a lubricant composition comprising the lube base oil.
