Two stage fixed-bed catalytic process for upgrading pyrolysis oil to BTX

A system for upgrading pyrolysis oil, the system comprising:

• a first fixed-bed reactor comprising a first catalyst bed and a second catalyst bed disposed downstream of the first catalyst bed, where:
• the first catalyst bed comprises a treating catalyst comprising:
• a first treating catalyst comprising a plurality of first particles and each of the plurality of first particles comprises alumina, binder, Mo, Ni, and P;
• or a second treating catalyst comprising a plurality of second particles and each of the plurality of second particles comprises Al2O3, SiO2, ZrO2, NiO, and WO3;
• or both;
• the second catalyst bed comprises a mixed metal oxide catalyst;
• the first fixed-bed reactor is operable to contact a pyrolysis oil feed with hydrogen in the presence of the treating catalyst and the mixed metal oxide catalyst to produce an intermediate stream comprising light aromatic compounds that include mono-aromatic compounds, di-aromatic compounds, tri-aromatic compounds, or combinations thereof;
• a second fixed-bed reactor downstream of the first fixed-bed reactor and comprising a mesoporous supported metal catalyst, where:
• the second fixed-bed reactor is operable to contact the intermediate stream with hydrogen in the presence of the mesoporous supported metal catalyst to produce a second reactor effluent comprising aromatic compounds having six to eight carbon atoms;
• and
• the mesoporous supported metal catalyst comprises nickel and tungsten impregnated onto a mesoporous support comprising alumina and at least one zeolite.
