Abstract

Dans un procédé de production de chlorure d'aluminium par condensation de chlorure d'aluminium gazeux dans un lit fluidisé de particules de chlorure d'aluminium, on introduit le chlorure d'aluminium gazeux dans le lit avec une vitesse d'entrée de 18 m/s à 90 m/s. On maintient également la dimension des particules de chlorure d'aluminium dans le lit à moins de 500 microns, en enlevant périodiquement les plus grosses particules qui restent à la partie inférieure du lit fluidisé. Le chlorure d'aluminium obtenu a une pureté permettant de l'utiliser dans un procédé de réduction électrolytique pour la production d'aluminium métallique.
