摘要： The present disclosure provides a method of producing dechlorinated waste plastic pyrolysis oil, the method including: (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 T f at a heating rate R 1 of 2 °C/min or less; and (S3) recovering pyrolysis oil pyrolyzed in the reactor, wherein the step (S2) includes one or more temperature plateaus in which a predetermined temperature T 1 is maintained at a temperature of 100°C or higher for a predetermined time.

摘要： The present invention provides a method and device for refining waste plastic pyrolysis oil, the method including: (S1) subjecting a waste plastic pyrolysis oil feedstock to a heat treatment by charging the waste plastic pyrolysis oil feedstock into a rotary kiln reactor and increasing a temperature of the rotary kiln reactor; (S2) recovering a gas component from a product in the step (S1); (S3) separating a high boiling point wax component from the recovered gas component and re-supplying the separated high boiling point wax component to the rotary kiln reactor in the step (S1); and (S4) recovering refined oil from the gas component from which the high boiling point wax component is removed.
