METHOD FOR PRODUCING LUBRICANT BASE OIL

A method for producing a lubricant base oil includes a first hydrogenation treatment step of bringing a hydrogenation treatment catalyst and a light wax into contact with each other at temperature T1, and thereby obtaining a first treated oil; a second hydrogenation treatment step of bringing the hy...

Beschreibung
Zusammenfassung:	A method for producing a lubricant base oil includes a first hydrogenation treatment step of bringing a hydrogenation treatment catalyst and a light wax into contact with each other at temperature T1, and thereby obtaining a first treated oil; a second hydrogenation treatment step of bringing the hydrogenation treatment catalyst and a heavy wax into contact with each other at temperature T2, and thereby obtaining a second treated oil; and a base oil production step of obtaining a lubricant base oil from a feedstock oil containing at least one selected from the group consisting of the first treated oil and the second treated oil, in which the hydrogenation treatment catalyst is a catalyst obtained by supporting one or more metals selected from the elements of Group 6, Group 8, Group 9, and Group 10 of the Periodic Table of Elements, on an inorganic oxide support.
