| abstract |
The present invention relates to an adsorbent comprising a zeolite-based phase and a non-zeolitic-based phase, the adsorbent having: less than or equal to 30 m2. The surface area outside g-1 is preferably less than or equal to 20 m2. G-1, a zeolite-based phase comprising at least one zeolite of the X-type FAU structure, and a pore size distribution determined by mercury intrusion according to standard ASTM D 4284-83 and represented by a volume distribution dV/dlogDHg, wherein the DHg is apparent The pore size and V-type pore volume are between 10 nm and 250 nm (including the limit).nThe invention also relates to a process for the manufacture of the adsorbent and to the use thereof, in particular for the separation of xylene isomers. |
