1. A multi-stage process for upgrading a mixed pyrolysis oil comprising polyaromatic compounds to benzene, toluene, ethylbenzene, and xylenes (BTEX), the method comprising:
combining light pyrolysis oil, wherein the light pyrolysis oil comprises paraffins, BTEX, mono-aromatics, naphthalenes, indenes, mono-naphthenes, and dicyclopentadiene, with heavy pyrolysis oil to form the mixed pyrolysis oil;
upgrading the mixed pyrolysis oil in a slurry-phase reactor zone to produce intermediate products, wherein the slurry-phase reactor zone comprises a mixed metal oxide catalyst; and
hydrocracking the intermediate products in a fixed-bed reactor zone to produce the BTEX, wherein the fixed-bed reactor zone comprises a mesoporous zeolite-supported metal catalyst.
