Abstract
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.
Claims12
A method of preparing at least two lube base oil products, the method comprising:
- (a) providing a feed stream;
- (b) separating the feed stream into at least two fraction streams, comprising a first fraction stream a second fraction stream, wherein the separating of the feed stream comprises solvent extraction, or adsorption, or both;
- and
- (c) introducing the at least two fraction streams into a first hydro-processing treatment, followed by a second hydro-processing treatment to produce at least two product streams,
- wherein the first product stream has a higher viscosity index (VI) than the second product stream.
A method of preparing at least two lube base oil products, the method comprising:
- (a) providing a feed stream;
- (b) introducing the feed streams into a first hydro-processing treatment to produce a treated stream, wherein the separating of the feed stream comprises solvent extraction, or adsorption, or both,
- (c) separating the treated stream to produce at least two fraction streams;
- and
- (d) introducing the at least two fraction streams into a second hydro-processing treatment to produce at least two product streams,
- wherein the first hydro-processing treatment comprises hydro-treatment (HDT), or hydrocracking (HCK), or both,
- wherein the second hydro-processing treatment comprises hydro-dewaxing (HDW), hydro-finishing (HDF), or both, and
- wherein the first product stream has a higher viscosity index (VI) than the second product stream.
A method of preparing at least two lube base oil products, the method comprising:
- (a) providing a feed stream;
- (b) introducing the feed streams into a first hydro-processing treatment to produce a first treated stream, wherein the separating of the feed stream comprises solvent extraction, or adsorption, or both
- (c) introducing the at first treated streams into a second hydro-processing treatment to produce a second treated stream, and
- (d) separating the second treated stream to produce at least two product streams,
- wherein the first hydro-processing treatment comprises hydro-treatment (HDT), or hydrocracking (HCK), or both,
- wherein the second hydro-processing treatment comprises hydro-dewaxing (HDW), hydro-finishing (HDF), or both, and
- wherein the first product stream has a higher viscosity index (VI) than the second product stream.
