FIELD: sorbents. SUBSTANCE: agglomerated zeolite adsorbents based on faujasite with Si/Al ratio within a range of 1-1.15 subjected to at least 70% barium and possibly potassium ion exchange and containing zeolitization-active binder are prepared by agglomeration of zeolite powder with binder followed by barium ion exchange and activation of ion-exchange products. Adsorbents are particularly well fit for liquid-phase adsorption of p-xylene from aromatic C8 fractions in fluidized-bed processes. EFFECT: increased selective sorption capacity. 16 cl, 7 tbl, 10 ex
