Abstract
Provided is a method of producing dechlorinated waste plastic pyrolysis oil. The method includes (S1) putting a waste plastic feedstock containing moisture into a reactor; (S2) pyrolyzing the waste plastic feedstock by heating the reactor to a target temperature Tf at a heating rate R1 of 2° C./min or less; and (S3) recovering pyrolysis oil pyrolyzed in the reactor. Step (S2) includes one or more temperature plateaus in which a predetermined temperature T1 is maintained at a temperature of 100° C. or higher for a predetermined time.
