Abstract
Provided is a pyrolysis method of waste plastics including the steps of inputting waste plastics to a batch reactor and performing heating to produce a waste plastic melt at a first temperature; heating the waste plastic melt to remove chlorine from the melt at a second temperature; and heating the waste plastic melt from which chlorine has been removed to produce a pyrolysate at a third temperature. The batch reactor is sequentially heated in a direction from a raw material inlet to a reaction product outlet so that the temperature is raised from the first temperature to the third temperature.
