CA 2545211

The invention relates to a method for regenerating reforming catalysts. The catalyst generally comprises at least one precious metal, preferably a metal from group VIII of the periodical classification of elements, optionally at least one additional metal, at least one halogen and at least one porous medium. The inventive method comprises at least one spent catalyst combustion phase and at least one oxyhalogenation stage, said stages being carried out in a single regeneration area wherein the catalyst to be regenerated is located in the form of a fluidized bed.

L'invention concerne un procédé de régénération de catalyseurs de reforming, le catalyseur comprenant généralement au moins un métal précieux, de préférence un métal du groupe VIII de la classification périodique des éléments, éventuellement au moins un métal additionnel, au moins un halogène et au moins un support poreux, le procédé selon l'invention comportant au moins une étape de combustion du catalyseur usé et au moins une étape d'oxyhalogénation, ces étapes étant réalisées dans une même zone unique de régénération dans laquelle la catalyseur à régénérer s'y trouve sous la forme d'un lit fluidisé.
