Abstract

Agglomérés d'alumine à bonne résistance mécanique, de granulométrie réglable de telle sorte qu'elle soit adaptée aux exigences techniques de l'utilisateur, obtenus par compactage d'un << produit intermédiaire >> provenant de la décomposition incomplète de sulfate d'aluminium hydraté répondant à la formule Al2 O3 , xSO3 , yH2 O, contenant de 1 à 15 % en poids de S exprimé en SO3 , 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 ou creux, plaquettes, etc.Alumina agglomerates with good mechanical strength, of adjustable particle size so that it is adapted to the technical requirements of the user, obtained by compacting an "intermediate product" resulting from the incomplete decomposition of aluminum sulphate hydrate corresponding to the formula Al2 O3, xSO3, yH2 O, containing from 1 to 15% by weight of S expressed as SO3, 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 or hollow cylinders, platelets, etc.
