Abstract: Provided herein are catalysts for dewaxing of a feedstock, the catalyst comprising between about 40 wt. % and about 99.9 wt. % zeolite, between about 0 wt. % and about 40 wt. % binder and at least about 0.1 wt. % noble metal, as well as catalyst systems, methods and products produced using the catalysts. The zeolite having a crystal comprising a largest included sphere less than or equal to about 7.5 angstroms, a largest diffusing sphere greater than or equal to about 5.0 angstroms, and a silica to alumina ratio greater than or equal to about 100:1. The catalyst having a temperature-programmed ammonia desorption (“TPAD”) of less than about 0.25 mmol/g.

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.
