Abstract
The present invention provides a method for producing waste plastic pyrolysis oil, the method comprising: a pyrolysis process of producing pyrolysis gas by introducing waste plastic into a pyrolysis reactor; and a hardening process of producing pyrolysis oil by injecting the pyrolysis gas into a hot filter filled with a neutralizer, wherein the pyrolysis oil contains, on the basis of the total weight, 50% by weight or more of naphtha having a boiling point of 150° C. or less and kero having a boiling point of 150° C. to 265° C. and less than 100 ppm of chlorine.
Claims18
A method for producing waste plastic pyrolysis oil, the method comprising:
- a pyrolysis process of producing pyrolysis gas by introducing waste plastics into a pyrolysis reactor at a temperature of 400 to 550° C.;
- and
- a lightening process of producing pyrolysis oil by directly introducing the pyrolysis gas into a hot filter filled with a neutralizing agent,
- wherein the pyrolysis oil contains 50 wt % or more of naphtha having a boiling point of 150° C. or lower and kero having a boiling point of 150 to 265° C., and less than 100 ppm of chlorine, with respect to the total weight of the pyrolysis oil.
