A process for regenerating used catalyst particles contaminated with carbonaceous and/or sulfur-containing materials, which process comprises the steps of: a) contacting said particles in a fluidized bed with an oxygen-containing gas at an elevated temperature whereby at least part of the contaminants is removed, and b) passing the thus treated catalyst particles to a moving belt and causing the belt to move said catalyst particles through a furnace zone, which is maintained at a temperature sufficient to remove the remaining portion of the contaminants from the catalyst particles.

Ce procédé de régénération de particules de catalyseur épuisé, contaminées par des matériaux carbonés et/ou contenant du soufre, comprend les étapes consistant: a) à mettre en contact ces particules dans un lit fluidisé avec un gaz contenant de l'oxygène, à une température élevée, ce qui permet ainsi d'enlever au moins une partie des contaminants, et b) à faire passer les particules de catalyseur ainsi traitées sur une courroie de transport, et à faire passer, à l'aide de celle-ci, les particules de catalyseur à travers une zone de combustion maintenue à une température suffisante pour enlever des particules de catalyseur la portion restante des contaminants.
