Zusammenfassung:	This invention relates to the catalytic cracking of a hydrocarbon feed. In particular, this invention relates to an apparatus and process utilizing a catalyst stripper section of a fluid catalytic cracking (FCC) reactor with chordal trays designed to provide improved stripping of hydrocarbons from spent FCC catalyst in an FCC reactor stripping zone. L'invention concerne le craquage catalytique d'une charge hydrocarbonée. Cette invention concerne en particulier un appareil et un procédé reposant sur l'utilisation d'une section d'épuiseur de catalyseur d'un réacteur de craquage catalytique fluide à plateaux chordaux permettant un meilleur épuisement des hydrocarbures d'un catalyseur de craquage catalytique fluide épuisé dans une zone d'épuisement du réacteur de craquage catalytique fluide.
