Abstract

A method for producing a lubricant base oil that has a predetermined boiling point range, the method including a first step of bringing a feedstock containing a first hydrocarbon oil having a boiling point in the above boiling point range and a second hydrocarbon oil having a lower boiling point than the boiling point range into contact with a hydroisomerization catalyst, wherein the catalyst contains a support that includes a zeolite having a one-dimensional porous structure including a 10-membered ring and a binder, and platinum and/or palladium supported on the support.

First claim

The invention claimed is:

1. A method for producing a lubricant base oil that has a predetermined boiling point range, the method comprising:
a first step of, in the presence of hydrogen, bringing a feedstock containing a first hydrocarbon oil having a boiling point in the predetermined boiling point range and a second hydrocarbon oil having a lower boiling point than the predetermined boiling point range into contact with a hydroisomerization catalyst,
wherein the catalyst contains a support that includes a zeolite having a one-dimensional porous structure including a 10-membered ring and a binder, and platinum and/or palladium supported on the support,
a carbon content of the catalyst is 0.4 to 3.5% by mass,
a micropore volume per unit mass of the catalyst is 0.02 to 0.12 cc/g,
the zeolite is derived from an ion-exchanged zeolite obtained by ion-exchanging an organic template-containing zeolite that contains an organic template and has a one-dimensional porous structure including a 10-membered ring in a solution containing ammonium ions and/or protons, and
a micropore volume per unit mass of the zeolite contained in the catalyst is 0.01 to 0.12 cc/g.

2. The method according to claim 1 , wherein a content of the first hydrocarbon oil in the feedstock is 5 to 60% by volume based on a total amount of feedstock.

3. The method according to claim 1 , wherein the first hydrocarbon oil has a boiling point of at least 520° C. and the second hydrocarbon oil has a boiling point range of 330° C. to less than 520° C.

4. The method according to claim 1 , wherein the first hydrocarbon oil has a boing point range of 470° C. to less than 520° C. and the second hydrocarbon oil has a boiling point range of 330° C. to less than 470° C.

5. The method according to claim 1 , further comprising a second step of obtaining a hydrorefined oil by hydrorefining a dewaxed oil obtained in the first step, and a third step of fractionating a base oil fraction having the boiling point range from the hydrorefined oil.
