Abstract

Procédé et installation pour produire de l’hydroxyde d’aluminium. Une cuve 1 reçoit en continu de l’eau, de l’aluminium réduit en fragments, et un catalyseur sous forme d’un hydroxyde métallique tel que KOH. Il y a dans la cuve un rotor (23) destiné à introduire de l’énergie mécanique, en particulier hydrodynamique, dans la cuve (1). La réaction physico-chimique suivante se produit dans le bain : Al + 3H2O + M(OH)n = Al(OH)3-M(OH)n + 3H2 L’énergie hydrodynamique introduite dans le bain par le rotor (23) casse la liaison physico-chimique entre Al(OH)3 qui passe en solution dans le bain et M(OH)n qui précipite. Une fraction liquide du bain est prélevée par une sortie (9) pour passer dans un sécheur (16) qui extrait l’hydroxyde d’aluminium. Le catalyseur précipité (14) et la vapeur dégagée par le séchage sont recyclés via un condenseur (19) et une entrée de recirculation (7). Figure pour l’abrégé : Fig.1Process and installation for producing aluminum hydroxide. A tank 1 continuously receives water, aluminum reduced to fragments, and a catalyst in the form of a metal hydroxide such as KOH. There is a rotor (23) in the tank intended to introduce mechanical energy, in particular hydrodynamic energy, into the tank (1). The following physico-chemical reaction occurs in the bath: Al + 3H2O + M(OH)n = Al(OH)3-M(OH)n + 3H2 The hydrodynamic energy introduced into the bath by the rotor (23) breaks the physico-chemical bond between Al(OH)3 which goes into solution in the bath and M(OH)n which precipitates. A liquid fraction of the bath is taken through an outlet (9) to pass into a dryer (16) which extracts the aluminum hydroxide. The precipitated catalyst (14) and the vapor given off by the drying are recycled via a condenser (19) and a recirculation inlet (7). Figure for the abstract: Fig.1
