<p>Disclosed is a method for producing a lubricant base oil, wherein a lubricant base oil is obtained through a first step in which a raw material oil containing a normal paraffin having 20 or more carbon atoms is subjected to an isomerization reaction so that the content of the normal paraffin having 20 or more carbon atoms is 6-20% by mass based on the total mass of hydrocarbons having 20 or more carbon atoms contained in the resultant reaction product, a second step in which a lubricant distillate fraction containing the hydrocarbons having 20 or more carbon atoms is separated from the reaction product of the first step, and a third step in which the lubricant distillate fraction obtained in the second step is separated into dewaxed oil and a wax component by solvent dewaxing.</p> |
