Abstract
The present invention relates to zeolite adsorbents based on agglomerated crystals of zeolite EMT comprising barium and/or potassium. These adsorbents find applications in the separation of aromatic C8 isomer fractions, especially of xylenes, in the separation of substituted toluene isomers, such as nitrotoluene, diethyltoluene and toluenediamine, and in the separation of cresols, and in the separation of polyhydric alcohols, such as sugars.
