Abstract:
Method of producing pyrolysis products from a mixed plastics stream along with an associated system for processing mixed plastics. The method includes conducting pyrolysis of a plastic feedstock to produce a stream of plastic pyrolysis oil; feeding the plastic pyrolysis oil to an aromatization unit having an aromatization reactor with an aromatization catalyst disposed therein to generate an aromatics rich stream; and passing the aromatics rich stream to an aromatic recovery complex to separate the aromatics rich stream into a BTX fraction, a gasoline blending fraction, a gas fraction comprising hydrogen and C1-C4 hydrocarbons, and an aromatic bottoms fraction comprising hydrocarbons boiling above 180° C., where the BTX fraction consists of benzene, toluene and mixed xylenes and the gasoline blending fraction comprises aliphatic hydrocarbons with a boiling range from C5 hydrocarbon up to the aromatic bottoms fraction.
