  • Fluid catalytic reactors which include flow directors
    Patent number: 10589242
    Abstract: According to one or more embodiments, a fluid catalytic reactor may include a riser, a lower reactor portion, a transition portion, and a flow director. The riser may include a cross-sectional area, and the lower reactor portion may include a cross-sectional area. The transition portion may attach the riser to the lower reactor portion. The cross-sectional area of the riser may be less than the cross-sectional area of the lower reactor portion such that the transition portion is tapered inward from the lower reactor portion to the riser. The flow director may be positioned at least within an interior region of the transition portion. The flow director may include a body which affects the velocity profile of fluids moving from the lower reactor portion to the riser.

  • Methods for designing scaled-up fluid catalytic reactors
    Patent number: 10507448
    Abstract: According to one or more embodiments of the present disclosure, a fluid catalytic reactor may be scaled-up by a method that includes one or more of constructing, operating, observing, or obtaining data related to a template fluid catalytic reactor comprising a template riser, a template lower reactor portion, and a template transition portion connecting the template riser and the template lower reactor portion. The method may further include one or more of constructing or operating a scaled-up fluid catalytic reactor based on the template fluid catalytic reactor.
