Abstract
Provided are a method of producing a lubricating base oil composition including a) reacting at least a part of waste plastic pyrolysis oil having a boiling point in a range higher than 340° C. to remove impurities and structurally isomerizing the oil; and b) hydroisomerizing at least a part of the product of step a), and a lubricating base oil composition produced therefrom. A lubricating base oil, which has more methyl branches than petroleum-based lubricating base oil, to have improved low-temperature properties may be provided.
