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 nitrate d'aluminium hydraté contenant 0,5 à 15 % en poids d'oxyde d'azote exprimé en N2 O5 , puis granulation du produit compacté, et traitement thermique du produit granulé, ainsi que leur procédé d'obtention. Les agglomerés d'alumine ont une surface spécifique comprise entre 2 et 150 m**2/g et peuvent se présenter sous des formes diverses telles que granulés, boulets, cylindres pleins ou creux, plaquettes...Alumina agglomerates of good mechanical strength, of granulometry - adjustable so that it is adapted to the technical requirements of the user, obtained by compacting an "intermediate product" resulting from the incomplete decomposition of nitrate of hydrated aluminum containing 0.5 to 15% by weight of nitrogen oxide expressed as N2 O5, 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 150 m ** 2 / g and can be in various forms such as granules, balls, solid or hollow cylinders, platelets, etc.
