ABSTRACT:
Alumina agglomerates having controlled porosity and excellent mechanical properties, well suited as catalyst supports and adsorbents, are produced by (a) agglomerating an alumina powder prepared by rapidly dehydrating an aluminum hydroxide, (b) aging the agglomerates thus formed in an atmosphere of controlled humidity, (c) impregnating such aged agglomerates with a solution of at least one acid, (d) hydrothermally treating the thus impregnated agglomerates in a confined enclosure, and then (e) drying and calcining the agglomerates thus treated.
