Alumina having a novel pore structure characterized by the absence of macropores, no more than 5 % of the total pore volume in pores greater than 350 .ANG., a high pore volume (greater than 0.8 cc/g measured by mercury intrusion) and a bi-modal pore volume distribution character, where the two modes are separated by 10 to 200 .ANG., and the primary pore mode is larger than the median pore diameter (MPD), calculated either by volume or by surface area, the MPD by volume being itself larger than the MPD by surface area. Also provided is a method of making such alumina, and catalysts made therefrom.
Alumine présentant une nouvelle structure poreuse caractérisée par l'absence de macropores, en quantité non supérieure à 5 % du volume total des pores supérieur à 350 .ANG., par un volume de pores important (supérieur à 0,8 cc/g mesuré par intrusion de mercure) et par une distribution volumique poreuse bimodale, dans laquelle les deux modes sont séparés par 10 à 200 .ANG., le mode de pore primaire étant supérieur au diamètre de pore moyen (MPD), calculé soit en fonction du volume, soit de la zone de surface, le MPD en volume étant supérieur au MPD en zone de surface. Elle concerne également un procédé d'élaboration de cette alumine et des catalyseurs fabriqués à base de cette alumine.
