Abstract
A method and associated system for producing refined hydrocarbons from waste plastics. The method and system provide for: pretreating waste plastics; producing pyrolysis gas by introducing the waste plastics pretreated in the pretreatment process into a pyrolysis reactor; producing in a lightening process pyrolysis oil by introducing the pyrolysis gas into a hot filter; and subjecting the pyrolysis oil to solvent extraction, wherein a liquid condensed in the hot filter is re-introduced into the pyrolysis reactor. The system produces refined hydrocarbons from the waste plastics.
