Abstract

L'invention concerne l'industrie de l'aluminium. Elle concerne un procédé de production d'Al métallique dans lequel de l'oxyde de carbone gazeux, dégagé à très haute température par réaction du carbure d'aluminium avec l'alumine, est refroidi par contact avec une scorie d'alumine fondue à une température inférieure, pour causer une réaction inverse du sous oxyde d'aluminium et de la vapeur d'Al, avec un transfert consécutif de chaleur à la scorie d'aluminium fondue Application à la fabrication d'aluminium par réduction carbothermique d'alumine.
