The present invention relates to a method for distilling pyrolytic fuel oil, in which a mixture, containing a second distillate in which when a volume reduction of 10% occurs on a distillation curve of pyrolytic fuel oil measured by using an ASTM D86 method, distillation temperature is equal to or higher than 250 degrees Celsius and equal to or lower than 400 degrees Celsius, a softening point is equal to or higher than 0 degrees Celsius and equal to or lower than 50 degrees Celsius, and an aromatization level (f_a) value is equal to or higher than 0.60, is used as raw material for distillation. Accordingly, an increase in viscosity of residual oil can be mitigated during high-temperature distillation, and thus a recovery rate of naphthalene can be improved via distillation performed at high temperature. |
