Beschreibung
Zusammenfassung:	Disclosed are a porous alumina material, a preparation therefor and a use thereof. An interior of the porous material has spherical or sphere-like cavities in a substantially ordered distribution. The cavities have an average diameter of 100-500 nm, and at least some adjacent cavities are connected by means of mesopores. The porous alumina material is suitable for use as a carrier for preparing a heavy oil hydrogenation processing catalyst or a carrier for a catalyst used in other macromolecular catalytic processes. L'invention concerne un matériau d'alumine poreux, sa préparation et son utilisation. L'intérieur du matériau poreux présente des cavités sphériques ou de type sphère selon une distribution sensiblement ordonnée. Les cavités ont un diamètre moyen de 100 à 500 nm, et au moins certaines cavités adjacentes sont reliées au moyen de mésopores. Le matériau d'alumine poreux est approprié pour être utilisé comme support pour préparer un catalyseur de traitement d'hydrogénation des huiles lourdes ou comme
