Abstract
A regenerator design and method are provided which rely upon a segmented regeneration gas distributor grid to vary regeneration gas flow upwardly through the bed of catalyst above. The design includes an expanding annular section formed by a curved vertically extending baffle positioned adjacent and downstream of the catalyst tangential inlet and a radical dilute phase baffle extending from slightly beneath the bed surface to above the cyclone inlets. The width of the dilute phase baffle is from the wall of the regenerator to the center thereof, and beyond the rim of the catalyst outlet. Further, all cyclone diplegs between the outlet and inlet should be positioned to discharge tangentially to the swirl.
