Abstract
An amorphous mesoporous alumina having a connectivity (Z) greater than 2.7 is described. The present invention also relates to the process for preparing the said alumina, comprising at least one precipitation step of at least one aluminum salt, at least one heating step of the suspension obtained, a thermal treatment step to form the alumina gel, a gentle drying step or spray drying step, a moulding step of the powder obtained, and a final thermal treatment step in order to obtain the alumina.
