Abstract
Embodiments of the present disclosure relate to a method for producing refined hydrocarbons from waste plastics, the method including: a pretreatment process of pretreating waste plastics; a pyrolysis process of producing pyrolysis gas by introducing the waste plastics pretreated in the pretreatment process into a pyrolysis reactor; a lightening process of producing pyrolysis oil by introducing the pyrolysis gas into a hot filter; and a distillation process of distilling the pyrolysis oil to obtain refined hydrocarbons, wherein a liquid condensed in the hot filter is re-introduced into the pyrolysis reactor, and a system for producing refined hydrocarbons from waste plastics.
