Title
(EN) MINIMIZING COKE FORMATION IN A REACTOR STRIPPER
(FR) MINIMISATION DE LA FORMATION DE COKE DANS UNE COLONNE DE RECTIFICATION DE RÉACTEUR
Abstract
(EN)
The presently disclosed subject matter relates to systems and methods for catalyst regeneration. In particular, the presently disclosed subject matter provides for an integrated fluidized bed reactor and catalyst regeneration system to minimize hydrocarbon accumulation. In one embodiment, the presently disclosed subject matter provides for a fluidized bed reactor unit including a catalyst riser having a partially perforated surface in close proximity to a reactor stripper.
