Abstract: A method is disclosed for fluidizing a spent catalyst in a regenerator during a combustion process. The combustor includes a vessel and an air distributor. The air distributor includes an air grid and a plurality of first nozzles extending from the air grid. Spent catalyst is introduced into the vessel. Air is provided to the vessel via the plurality of first nozzles at a base combustion air rate. Additional air is provided to the vessels via a plurality of second nozzles of a fluffing air distributor at a fluffing air rate that is between 0.5 wt % and 10 wt % of the base combustion air rate to fluidize the catalyst. The second nozzles have outlets that are disposed below the air grid and above a bottom head of the vessel.

Abstract: A quench system and process for cooling high temperature gases is presented. The quench system includes a frustum, or conic, shaped section having an inlet at the smaller end of the quench section and the outlet at the larger end of the quench section. The system includes spray nozzles having openings flush with the wall of the quench section. The process includes spraying a large volume of liquid in small droplets for rapid heat transfer and vaporization of the quench liquid.

Abstract: Catalyst regenerators and methods of their use are provided. A catalyst regenerator includes a combustion chamber with a combustion chamber diameter and a combustion chamber bottom. A mixing chamber is fluidly coupled to the combustion chamber at the combustion chamber bottom, where the mixing chamber has an exterior wall and a mixing chamber diameter less than the combustion chamber diameter. A first and second catalyst inlet are fluidly coupled to the mixing chamber, and a mixing cylinder is within the mixing chamber. The mixing cylinder and the exterior wall define an annular space there-between, and the mixing cylinder includes a cylinder opening.

Abstract: In an FCC apparatus in which swirl arms are used to discharge gas and catalyst from a riser, the swirling movement of the catalyst particles is inhibited while impeding the catalyst particles and gaseous products from exiting the disengaging chamber and entering a reactor annulus. The catalyst particles and gaseous products pass through a tunnel comprising a vertical wall to enter the reactor annulus. The vertical wall presents a face that is opposed to the angular direction in which the catalyst particles and gaseous products swirl.
A baffle may be located at the intersection between the reactor annulus and the disengaging chamber to deflect catalyst laterally in a stripping section after exiting the reactor annulus. The baffle may be equipped with openings to fluidize the large proportion of catalyst passing over this region to effectively pre-strip this catalyst before it enters a stripping section.-
