Title (EN) ZEOLITIC ADSORBENTS WITH LARGE EXTERNAL SURFACE AREA, PROCESS FOR PREPARING SAME AND USES THEREOF
(FR) ADSORBANTS ZÉOLITHIQUES DE HAUTE SURFACE EXTERNE, LEUR PROCÉDÉ DE PRÉPARATION ET LEURS UTILISATIONS
Abstract: front page image
(EN)The present invention relates to zeolitic adsorbents based on agglomerated crystals of FAU zeolite comprising barium and/or potassium, with a large external surface area, combining optimum properties in terms of selectivity and mechanical strength. These adsorbents find applications in the separation of fractions of C8-aromatic isomers and in particular of xylenes, in the separation of isomers of substituted toluene such as nitrotoluene, diethyltoluene or toluenediamine, and in the separation of cresols, and polyhydric alcohols, such as sugars.
(FR)La présente invention concerne des adsorbants zéolithiques à base de cristaux agglomérés de zéolithe FAU comprenant du baryum et/ou du potassium, de haute surface externe, combinant des propriétés optimales en termes de sélectivité et de résistance mécanique. Ces adsorbants trouvent des applications dans la séparation de coupes d'isomères aromatiques en C8 et notamment des xylènes, dans la séparation d'isomères de toluène substitué tels que nitrotoluène, diéthyltoluène, toluènediamine, dans la séparation des crésols, et des alcools polyhydriques, tels que les sucres.
