| abstract |
The present invention relates to zeolite adsorbents based on small agglomerated crystals of barium-containing zeolite X combining optimum properties such as selectivity and mechanical strength. These adsorbents are used to separate C8 aromatic isomer fractions and in particular xylenes to separate substituted toluene isomers such as nitrotoluene, diethyltoluene or toluene diamine, to separate cresols and to separate polyhydric alcohols such as sugars. |
