The present invention relates to new mesoporous inorganic solids in the form of primary and/or secondary inorganic particles of D10>=1 mum and D50>=3 mum, preferably from D10>=2 mum and D50>=10 mum the size of which can go up to 10 mm, wherein the microporous volume (pores of size less than or equal to 2 mum) represents at most 10% of the total porous volume up to 300 nm. These solids can advantageously be used as catalytic component supports in polymerization reactions, as reaction catalysts in the refining and petrochemical fields, as adsorbents for separating the components of a gaseous or liquid mixture consisting of at least 2 different compounds and as chromatography column packing supports. |
