1. An agglomerated zeolite material comprising at least one mesoporous zeolite and optionally one or more non-mesoporous zeolites, the said agglomerated zeolite material having at least the following characteristics:
a total zeolite content of at least 70% by weight relative to the total weight of the agglomerated zeolite material, a content of mesoporous zeolite(s) of greater than or equal to 30%, a binder content, after calcinations performed at 950° C. for 1 hour, of less than or equal to 30%, a mean volume diameter (D50), or a length (largest dimension when the material is not spherical) of less than or equal to 7 mm, and either i) a bulk crushing strength (BCS) measured according to standard ASTM 7084-04 of between 0.5 MPa and 3 MPa, for a material with a mean volume diameter (D50), or a length (largest dimension when the material is not spherical), of less than 1 mm, limits inclusive, or ii) a grain crushing strength, measured according to standards ASTM D 4179 (2011) and ASTM D 6175 (2013), of between 0.5 daN and 30 daN for a material with a mean volume diameter (D50), or a length (largest dimension when the material is not spherical), of greater than or equal to 1 mm, limits inclusive. |
