Abstract
Various embodiments of the present disclosure relate to methods and system for producing refined hydrocarbons from waste plastic pyrolysis oil. The methods and system for producing refined hydrocarbons from waste plastic pyrolysis oil according to the embodiments of the present disclosure may minimize formation of an ammonium 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 methods and system for producing refined hydrocarbons according to embodiments of 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 prevented, and may produce refined hydrocarbons having a low content of impurities and a low content of olefins, and solid coke, from waste plastic pyrolysis oil.
