Abstract

A method for producing a hydroisomerization catalyst according to the present invention includes: a first step of preparing a catalyst to be treated, which contains a support having a one-dimensional porous structure including a 10-membered ring and at least one metal selected from the group consisting of: group 8 to 10 metals of the periodic table, Mo, and W supported on the hydroisomerization catalyst; and a second step of producing a hydroisomerization catalyst having a carbon content of 0.4 to 2.5% by mass by subjecting the catalyst to be treated to a coking treatment by means of a carbon-containing compound.

First claim

The invention claimed is:

1. A method for producing lubricant base oil, wherein the method comprises:
subjecting a catalyst to a coking treatment with a carbon containing compound, the coking treatment being at a temperature of 300° C. to 350° C. to obtain a hydroisomerization catalyst having a carbon content of 0.4% to 2.5% by mass, wherein the catalyst comprises a support having a one-dimensional porous structure including a 10-membered ring and at least one metal selected from the group consisting of group 8 to 10 metals of the periodic table, Mo, and W, supported on the catalyst; and
contacting a hydrocarbon feedstock containing normal paraffins having 10 or more carbon atoms with the hydroisomerization catalyst in the presence of hydrogen at a hydroisomerization temperature of 370° C. to 450° C.

2. The method for producing lubricant base oil according to claim 1 , wherein the catalyst is subjected to a coking treatment by using the hydrocarbon feedstock as the carbon-containing compound.

3. The method for producing lubricant base oil according to claim 1 , wherein the hydrocarbon feedstock is further hydrofinished and vacuum-distilled after the hydrocarbon feedstock is contacted with the hydroisomerization catalyst.

4. The method for producing lubricant base oil according to claim 1 , wherein the hydrocarbon feedstock is at least one selected from the group consisting of: atmospheric residues; vacuum residues; a vacuum gas oil; a slack wax; and a Fischer Tropsch synthetic wax.

5. The method for producing lubricant base oil according to claim 1 , wherein the hydrocarbon feedstock includes a fraction with a boiling point at atmospheric pressure of more than 360° C.

6. The method for producing lubricant base oil according to claim 1 , wherein the hydroisomerization catalyst has a volume of micropores per unit mass of the catalyst of 0.02 to 0.11 cc/g and a volume of micropores per unit mass of a zeolite contained in the catalyst of 0.04 to 0.12 cc/g.

7. The method for producing lubricant base oil according to claim 1 , wherein the hydroisomerization catalyst comprises at least one zeolite selected from the group consisting of: a ZSM-22 zeolite; a ZSM-23 zeolite; an SSZ-32 zeolite; and a ZSM-48 zeolite.

8. A method for producing lubricant base oil, wherein the method comprises:
subjecting a catalyst to a coking treatment with a carbon containing compound, the coking treatment being at a temperature of 300° C. to 350° C. to obtain a hydroisomerization catalyst having a carbon content of 0.4% to 2.5% by mass, wherein the catalyst comprises a support having a one-dimensional porous structure including a 10-membered ring and at least one metal selected from the group consisting of group 8 to 10 metals of the periodic table, Mo, and W, supported on the catalyst; and
contacting a hydrocarbon feedstock containing normal paraffins having 10 or more carbon atoms with the hydroisomerization catalyst in the presence of hydrogen at a hydroisomerization temperature of 370° C. to 450° C., wherein the hydrocarbon feedstock includes a fraction with a boiling point at atmospheric pressure of more than 360° C.
