| titleOfInvention | Method for preparing a mesoporous alumina from a dispersible gel prepared without forced drying |
| abstract | The invention concerns a method for preparing a mesoporous alumina having a total porous volume greater than 0.75 ml/g, comprising: a) at least one first step of precipitating alumina, from at least one base precursor and at least one acid precursor, wherein at least one of the base or acid precursors comprises aluminium, the flow rate of the acid and base precursor or precursors containing aluminium is controlled in such a way as to obtain a progress rate of said first step of between 40 and 100%; b) a heat treatment step for treating the suspension obtained at the end of step a); c) a step of filtering the obtained suspension; d) a step of eliminating at least some of the water at a temperature lower than 50°C for a period of between 5 minutes and 48 hours, in order to obtain a paste; e) a step of shaping the paste by mixing/extrusion in order to obtain the green material, said step e) being carried out with a total acid content of between 0 and 4% and a neutralisation rate of between 0 and 200%; and f) a heat treatment step. |
