Abstract: Systems and methods are provided for expanding the operating envelope for an FCC reaction system while also reducing or minimizing the net environmental CO2 emissions associated with the FCC reaction system and/or the resulting FCC products. In some aspects, reducing or minimizing net environmental CO2 emissions 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

Abstract: An isomerization catalyst is provided, along with corresponding systems and methods, which provides improved isomerization for bio-derived feeds in reaction environments where by-products from deoxygenation are present. The catalyst provides unexpectedly increased activity and/or selectivity in situations where, for example, a deoxygenation effluent is cascaded to the isomerization catalyst. Additionally, the isomerization catalyst can assist with reducing or minimizing hydrogen consumption during isomerization. The increased activity, stability, and/or reduced hydrogen consumption is achieved in part based on using a dispersion agent when adding base metals to the catalyst. In addition to the base metals, the catalyst includes a zeolitic framework structure suitable for isomerization.

Abstract: Systems and methods are provided for production of renewable jet fuel and/or jet fuel blending component fractions using a single stage reaction system. Although only a single separation stage is used, the systems and methods can reduce or minimize the volume of feedstock that is exposed to hydrocracking conditions while still producing a jet boiling range fraction having beneficial cold flow properties.
