Abstract
Systems and methods are provided for modifying the composition of the conversion catalyst in a reactor for oxygenate conversion during conversion of an oxygenate feed to allow for adjustment of the slate of conversion products. The modification of the conversion catalyst can be performed by introducing a substantial portion (relative to the amount of catalyst inventory in the reaction system) of make-up catalyst having a distinct composition relative to the conversion catalyst in the reaction system. Introducing the distinct composition of make-up catalyst can modify the composition of the conversion catalyst in the reactor to allow for changes in the resulting product slate. By introducing the distinct catalyst composition, the conversion catalyst in the reactor can correspond to a different composition of catalyst than the overall average catalyst composition within the catalyst inventory in the reaction system.
