There is provided a method for dewaxing a hydrocarbon oil for improving the life of a hydroisomerization catalyst. An aspect of a method for dewaxing a hydrocarbon oil according to the present invention comprises: a first step of subjecting a hydrocarbon oil in which a peroxide value is 100 ppm by mass or more to hydrotreating to obtain a material to be treated in which a peroxide value is 30 ppm by mass or less; and a second step of subjecting the material to be treated in which a peroxide value is 30 ppm by mass or less to hydroisomerization treatment using a hydroisomerization catalyst. |
