1. A method of converting a mixture of oxygenates to aromatic hydrocarbons, the method comprising:
providing a first oxygenate, the first oxygenate comprising a C1-C6 alkanol; providing a second oxygenate, the second oxygenate comprising a carboxylic acid, an aldehyde, an ester, or any combination thereof, wherein the second oxygenate has a hydrogen to carbon effective ratio of less than 1.6; producing a mixture of oxygenates, the mixture of oxygenates comprising at the first oxygenate and the second oxygenate, wherein the mixture of oxygenates has a total hydrogen to carbon effective ration of between 1.0 and 1.8; and exposing the mixture of oxygenates to an oxygenate conversion catalyst at an oxygenate conversion temperature and an oxygenate conversion pressure to produce aromatic hydrocarbons.
