Abstract

L'INVENTION CONCERNE UN PROCEDE DE PRODUCTION D'ALUMINE SPHERIQUE QUI CONSISTE A PREPARER UNE SOLUTION BASIQUE DE CHLORURE D'ALUMINIUM AYANT UNE CONCENTRATION EN ALUMINIUM DE 7 A 12 EN POIDS ET UN RAPPORT PONDERAL ALUMINIUMCHLORURE DE 0,3 A 0,8 EN FAISANT REAGIR DE LA GIBBSITE AVEC UNE SOLUTION AQUEUSE D'ACIDE CHLORHYDRIQUE A TEMPERATURE ELEVEE, A PREPARER UN HYDROSOL D'ALUMINIUM AYANT UNE CONCENTRATION EN ALUMINIUM DE 9 A 15 EN POIDS, ET UN RAPPORT PONDERAL ALUMINIUMCHLORURE DE L'ORDRE DE 0,8 A 1,5, EN FAISANT REAGIR LA SOLUTION AINSI PREPAREE AVEC DE L'ALUMINIUM METALLIQUE A UNE TEMPERATURE ELEVEE, A MELANGER CET HYDROSOL AVEC UN AGENT GELIFIANT, A DISPERSER LE MELANGE RESULTANT SOUS LA FORME DE GOUTTELETTES DANS UN MILIEU DE SUSPENSION AFIN DE FORMER DES PARTICULES D'HYDROGEL, A VIEILLIR LES PARTICULES AINSI OBTENUES DANS LE MILIEU DE SUSPENSION, PUIS DANS LE L'AMMONIAC AQUEUX, A LAVER A L'EAU, SECHER ET CALCINER. L'ALUMINE SPHERIQUE AINSI OBTENUE EST PRATIQUEMENT EXEMPTE DE SODIUM, MALGRE L'EMPLOI DE GIBBSITE COMME MATIERE PREMIERE.
