摘要： A method and associated system for producing refined hydrocarbons from waste plastics. The method and associated system provide for pretreating waste plastics; a producing a pyrolysis gas by introducing the waste plastics pretreated in the pretreatment process into a pyrolysis reactor; producing in a lightening process a pyrolysis oil by introducing the pyrolysis gas into a hot filter; dehydrating a first mixed solution, obtained by mixing the produced pyrolysis oil with washing water and a demulsifier, by applying a voltage to the first mixed solution; hydrotreating a second mixed solution obtained by mixing the dehydrated first mixed solution with a sulfur source to produce a refined pyrolysis oil from which impurities are removed; and coking the refined pyrolysis oil, wherein a liquid condensed in the hot filter is re-introduced into the pyrolysis reactor.

摘要： 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.

摘要： The present disclosure relates to a method and system for producing refined hydrocarbons from waste plastic pyrolysis oil. The method and system for producing refined hydrocarbons from waste plastic pyrolysis oil according to the present disclosure may minimize formation of an ammonium chloride salt (NH4Cl) and may prevent an adhesion phenomenon of impurity particles in a reactor in a refining process of waste plastic pyrolysis oil containing impurities including chlorine and nitrogen. In addition, the method and system for producing refined hydrocarbons according to the present disclosure may have excellent refining efficiency and may implement a long-term operation of a process because deactivation of a catalyst used in the process is reduced or prevented, and may produce refined hydrocarbons having a low content of impurities and a low content of olefins from waste plastic pyrolysis oil.
