Patent

CA 2557501

The invention relates to the partial recovery of discarded, spent, or waste fluid catalytic cracking (FCC) equilibrium catalyst by use of a separation device located off site, away from any FCC Process unit or Petroleum Refining area, whereby the separation of recoverable material is achieved by means of both magnetic properties exhibited from contaminated metals deposited on individual catalyst particles and inertial or momentum contributions based on size and density of each individual catalyst particle. The invention provides a process to recover twenty to forty percent of the . original discarded, spent, or waste FCC equilibrium catalyst for reuse.

L'invention concerne la récupération partielle d'un catalyseur d'équilibre de craquage catalytique fluide (FCC) rejeté, épuisé ou résiduaire, grâce à un dispositif de séparation situé à l'extérieur, loin d'une quelconque unité de traitement FCC ou zone de raffinage du pétrole. La séparation du matériau récupérable est réalisée sur la base tant de propriétés magnétiques de métaux contaminés déposés sur des particules catalysantes individuelles que de contributions inertielles ou dynamiques basées sur la taille et la densité de chaque particule catalysante individuelle. On décrit un processus qui permet de récupérer vingt à quarante pour cent du catalyseur d'équilibre FCC initial rejeté, épuisé ou résiduaire, en vue de sa réutilisation.
