To provide a method for producing a lubricant base oil, with which a lubricant base oil having low viscosity, a high viscosity index and low evaporation property is efficiently and inexpensively obtained.
The method for producing a lubricant base oil comprises a process for preparing a hydrocracking catalyst obtained by supporting at least one kind of a metal of the group VIa of the periodic table and at least one kind of a metal of the group VIII on a carrier having ≤80% fraction of desorption amount at 300-800°C based on the total desorption amount of NH3 in NH3 desorption temperature-dependency evaluation, a process for hydrocracking a raw material oil containing ≥50 vol.% of slack-wax in the presence of the hydrocracking catalyst under 0.1-14 MPa hydrogen partial pressure at 230-430°C average reaction temperature at 0.3-3.0hr-1 LHSV at 50-14,000 scf/b ratio of hydrogen to oil, a process for distilling and separating the obtained hydrocracked oil to give a lubricating oil fraction and a process for dewaxing the lubricating oil fraction.
