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.

Abstract: In accordance with one or more embodiments of the present disclosure, a multi-stage process for upgrading a mixed pyrolysis oil comprising polyaromatic compounds to benzene, toluene, ethylbenzene, and xylenes (BTEX) includes combining light pyrolysis oil 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.

Abstract: A process for producing isopentane and isoamylene can comprise passing a feed stream comprising C5 hydrocarbons through a hydrodesulfurization assembly to produce a first stream: passing the first stream to a first separation assembly to produce a second stream and a first separated stream: passing the second stream to a deisopentanizer assembly to produce a second separated stream comprising isopentane, a third separated stream comprising C6+ hydrocarbons, and a raffinate stream comprising C5 hydrocarbons; and passing the raffinate stream to a reactor assembly to produce a reaction product stream comprising isoamylene. The present disclosure also provides for a system for producing isopentane and isoamylene.
