Systems and methods are provided for expanding the operating envelope for an FCC reaction system while also reducing or minimizing the net environmental COemissions associated with the FCC reaction system and/or the resulting FCC products. In some aspects, reducing or minimizing net environmental COemissions can be achieved during processing of unconventional feeds, such as feeds that are traditionally viewed as having insufficient tendency to coke in order to maintain heat balance within an FCC reaction system. In other aspects, this can correspond to expanding the production of diesel within an FCC reaction system by modifying the reaction conditions in a manner that can cause a reaction system to fall out of heat balance (relative to the heat needed to maintain a target operating temperature) even when using conventional feeds.
