Abstract: A reactor system and method for catalytic dehydrogenation of saturated C3-C6 hydrocarbons within a reactor placed within a reactor disengager, where the reactor is open at the bottom thereof and open to the disengager, and the exit riser from the reactor is not hard coupled to at least one downstream cyclone. This configuration permits controlling the amount of catalyst within the reactor by varying the level of catalyst in the reactor disengager outside the reactor and permits controlling total catalyst hold-up and/or weight hourly space velocity (WHSV) independently from catalyst flow from the catalyst regenerator.

Abstract: A method and system for increasing olefin production and quality from a hydrocarbon feed comprising a fully integrated multi-stage catalyst regeneration zones with multi-stage reaction zones in series and/or parallel. The multi-stage regeneration with at least one partial and one full burn zone provides an independent control to achieve the lowest possible regenerated catalyst temperature, resulting in highest possible catalyst to oil ratio required to maximize olefins yields through increased catalytic cracking in a multi stage FCC riser/risers.

Abstract: The present disclosure includes a system for producing low carbon olefins and/or aromatics from raw material comprising naphtha. The system can include a reaction unit that includes a fast fluidized bed reactor, a stripping unit that includes a stripper, and a regeneration unit. The reactor unit is adapted to allow the catalytic cracking of naphtha and to output reaction unit effluent material (spent catalyst and product gas) into the stripping unit, which is adapted to output product gas. The stripping unit is connected to and in fluid communication with the regeneration unit such that the stripping unit supplies the spent catalyst from the reaction unit to regeneration unit. The regeneration unit is adapted to regenerate the spent catalyst to form regenerated catalyst. The regeneration unit is connected to and in fluid communication with the fast fluidized bed reactor such that, in operation, regenerated catalyst can be sent to the fast fluidized bed reactor of the reaction unit.

Abstract: A process for upgrading a naphtha feed includes separating the naphtha feed into at least a light naphtha fraction, contacting the light naphtha fraction with hydrogen in the presence of at least one cyclization catalyst, and contacting the cyclization effluent with at least one cracking catalyst. Contacting the light naphtha fraction with hydrogen in the presence of at least one cyclization catalyst may produce a cyclization effluent comprising a greater concentration of naphthenes compared to the light naphtha fraction. Contacting the cyclization effluent with at least one cracking catalyst under conditions sufficient crack at least a portion of the cyclization effluent may produce a fluid catalytic cracking effluent comprising light olefins, gasoline blending components, or both. A system for upgrading a naphtha feed includes a naphtha separation unit, a cyclization unit disposed downstream of the naphtha separation unit, and a fluid catalytic cracking unit disposed downstream of the cyclization unit.

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
