    摘要： The present invention concerns an amorphous mesoporous alumina having a mesoporous median diameter by volume determined by mercury intrusion porosimetry greater than or equal to 16 nm, a mesoporous volume as measured by mercury intrusion porosimetry, greater than or equal to 0.5 ml/g, and a total porous volume measured by mercury porosimetry greater than 0.75 ml/g. The present invention also concerns a method for preparing said alumina, comprising: a) a first step of precipitating at least one basic precursor and at least one acid precursor in which at least one of the basic or acid precursors comprises aluminium, with a pH of the aqueous reaction medium of between 8.5 and 10.5, a temperature of between 20 and 90°C and for a period of between 2 minutes et 30 minutes, with a rate of progress of the first step of between 5 and 13%; b) a step of heating the suspension, c) a second step of precipitation by adding, into the suspension, at least one basic precursor and at least one acid precursor in which at least one of the basic or acid precursors comprises aluminium, with a pH of the reaction medium of between 8.5 and 10.5, a temperature of between 40 and 90°C and for a period of between 2 minutes and 50 minutes, with a rate of progress of the second step of between 87 and 95%; d) a filtering step; e) a drying step, f) a shaping step, g) a heat treatment step.
