1. A method for converting oxygenates to aromatics, comprising:
exposing a first feed comprising a first oxygenate feed comprising methanol and having an effective hydrogen index of at least about 1 and a first portion of a pyrolysis oil feed to an aromatization catalyst at a first location under effective conversion conditions to react methanol in the first oxygenate feed with pyrolysis oil in the first portion of the pyrolysis oil feed to form a first conversion effluent comprising one or more aromatic compounds, the volume percentage of the first portion of the pyrolysis oil feed being about 5 vol % to about 25 vol % of the volume of the first feed;
exposing at least a portion of the first conversion effluent and a second feed comprising a second oxygenate feed comprising methanol and having an effective hydrogen index of at least about 1 and a second portion of the pyrolysis oil feed to the aromatization catalyst under effective conversion conditions to react methanol in the second oxygenate feed with pyrolysis oil in the second portion of the pyrolysis oil feed to form a second conversion effluent comprising one or more aromatic compounds, the volume of the second feed being less than the volume of the first feed;
wherein the volume percentage of the first and second portions of the pyrolysis oil feed based on the total volume of the first and second feeds is greater than the volume percentage of the first portion of the pyrolysis oil feed in the first feed, and
wherein said aromatization catalyst comprises ZSM-5 and at least one metal from Groups 8-14 of the Periodic Table.
