Abstract: The present disclosure relates to a method of refining waste plastic pyrolysis oil, the method including the steps of: S1) pyrolyzing waste plastics to produce pyrolysis oil; S2) separating monomers from a depolymerization product recovered by depolymerizing polyethylene terephthalate (PET) with alcohol and adding a remaining depolymerization residue to the pyrolysis oil; S3) mixing the depolymerization residue with the pyrolysis oil to produce refined pyrolysis oil; and S4) separating the refined pyrolysis oil and the depolymerization residue. The refined pyrolysis oil may have a reduced content of impurities, such as nitrogen. Also provided is a method of removing nitrogen in pyrolysis oil by mixing, with pyrolysis oil, a residue generated during a recycling process of polyethylene terephthalate (PET), which should be disposed of as waste, and exhibits an effect of significantly reducing a content of nitrogen in pyrolysis oil.
