Abstract

A method for producing aromatic compounds from pyrolysis oil comprises: upgrading the pyrolysis oil to pyrolysis gasoline in a multi-stage reactor comprising a slurry-phase reactor and a fixed-bed reactor, wherein the slurry-phase reactor comprises a mixed metal oxide catalyst, and the fixed-bed reactor comprises a mesoporous zeolite-supported metal catalyst; aromatizing the pyrolysis gasoline in an aromatization unit; hydrodealkylating and transalkylating a product from the aromatization unit in a hydrodealkylation-transalkylation unit, thereby producing an aromatic stream; and processing the aromatic stream in an aromatics recovery complex to produce the aromatic compounds comprising benzene, toluene, and xylenes (BTX).
