Title:

METHOD FOR PRODUCING LUBRICANT OIL BASE-OIL

Document Type and Number:

WIPO Patent Application WO/2017/056550

Kind Code:

A1

Abstract:

Provided is a method for producing a lubricant oil base-oil that extends the life of a hydrocracking catalyst and increases the viscosity index of the lubricant oil base-oil. A method for producing a lubricant oil base-oil comprises: a first step of contacting a feedstock oil (4) containing aromatic hydrocarbons with a first hydrocracking catalyst (1) in the presence of hydrogen gas so as to obtain a first product oil (5A); and a second step of contacting the first product oil (5A) with a second hydrocracking catalyst (2) in the presence of hydrogen gas so as to obtain a second product oil (5B). The first hydrocracking catalyst (1) contains zeolite, and the second hydrocracking catalyst (2) contains an amorphous solid acid.
