Abstract
A method for producing a lubricant base oil, the method comprising a first step of fractionating, from a hydrocarbon oil containing a base oil fraction and a heavy fraction that is heavier than the base oil fraction, the base oil fraction and the heavy fraction, and a second step of obtaining a dewaxed oil by isomerization and dewaxing of the base oil fraction fractionated in the first step, wherein a hydrocracked oil obtained by hydrocracking the heavy fraction fractionated in the first step is returned to the first step.
