摘要：
The invention relates to an absorbent comprising a zeolite phase and a non-zeolite phase, said absorbent having: an external surface area less than or equal to 30 m
2 .g
-1 , preferably less than or equal to 20 m
2 .g
-1 , a zeolite phase comprising at least one X zeolite with FAU structure, and a pore diameter distribution, as determined by mercury intrusion according to the standard ASTM D4284-83 and expressed by the volume distribution dV/dlogDHg, where DHg is the apparent diameter of the pores, and V, the porous volume, the mode of which lies between 100 nm and 250 nm, terminals included. The invention also relates to a method for preparation of said absorbent and uses thereof, in particular for the separation of xylene isomers.
