Abstract: Systems and method for upgrading pyrolysis oil to produce greater value aromatic compounds includes combining heavy pyrolysis oil and a diluent to produce the pyrolysis oil feed withleast 30 wt. % multi-ring aromatic compounds boiling at greater than 360° C. The systems and methods include passing the pyrolysis oil feed to a fixed bed reactor having a hydrocracking catalyst that includes pellets having a particle size greater than or equal to 0.1 millimeter. The hydrocracking catalyst is a mixed metal oxide catalyst that includes a binder and mixed metal oxide particles or a supported metal oxide catalyst that includes molybdenum oxide and nickel oxide supported on a catalyst support material comprising a large-pore alumina. The methods may further include contacting the pyrolysis oil feed with the hydrogen in the presence of the hydrocracking catalyst at reaction conditions in the fixed bed reactor to produce a reaction effluent.
