Abstract

La présente invention concerne des agglomérés d'alumine à bonne résistance mécanique, de granulometrie réglable de telle sorte qu'elle soit adaptée aux exigences techniques de l'utilisateur, obtenus par compactage dun << produit intermédiaire >> provenant de la décomposition incomplete du chlorure d'aluminium hexahydraté contenant de 0,8 % à 15 % en poids de Cl, puis granulation du produit compacté, et traitement thermique du produit granulé, ainsi que leur procédé d'obtention. Les agglomérés d'alumine ont une surface spécifique comprise entre 2 et 120 m**2/g et peuvent se présenter sous des formes diverses telles que granules, boulets, Cylindres pleins creux, plaquettes, etcThe present invention relates to alumina agglomerates with good mechanical strength, of adjustable particle size so as to be adapted to the technical requirements of the user, obtained by compacting an "intermediate product" resulting from the incomplete decomposition of the chloride. aluminum hexahydrate containing 0.8% to 15% by weight of Cl, then granulation of the compacted product, and heat treatment of the granulated product, as well as the process for obtaining them. Alumina agglomerates have a specific surface area of between 2 and 120 m ** 2 / g and can be in various forms such as granules, balls, solid hollow cylinders, platelets, etc.
