Abstract
A method for upgrading mixed pyrolysis oil may include contacting the mixed pyrolysis oil with hydrogen in the presence of a mixed metal oxide catalyst at reaction conditions to produce a reaction effluent including light aromatic compounds. The mixed pyrolysis oil includes multi-ring aromatic compounds and is formed from light pyrolysis oil and heavy pyrolysis oil at a ratio of 10:90 to 40:60 with light pyrolysis oil representing a bottom stream of a gas steam cracker and heavy pyrolysis oil representing a bottom stream of a naphtha steam cracker. The mixed metal oxide catalyst includes a plurality of catalyst particles with each catalyst particles including a plurality of metal oxides. An associated system for upgrading mixed pyrolysis oil may include a pyrolysis upgrading unit housing the mixed metal oxide catalyst and a separation unit operable to separate used mixed metal oxide catalyst from the reaction effluent.
