  • Publication number: 20200316558
    Abstract: The present invention relates to zeolite adsorbents based on agglomerated crystals of zeolite X comprising barium, potassium, sodium and strontium. These adsorbents have applications in the separation of fractions of aromatic C8 isomers and in particular xylenes.
    Type: Application
    Filed: December 17, 2018
    Publication date: October 8, 2020
    Applicants: Arkema France, IFP Energies Nouvelles
    Inventors: Catherine Laroche, Ludivine Bouvier, Javier Perez-Pellitero, Marie-Laurence Labede
  • Patent number: 10675607
    Abstract: The present invention relates to zeolitic adsorbents based on agglomerated crystals of FAU zeolite containing barium and/or potassium, with large external surface area, combining optimum properties in terms of selectivity and mechanical strength. These adsorbents find applications in the separation of cuts of C8-aromatic isomers and notably of xylenes, in the separation of isomers of substituted toluene such as nitrotoluene, diethyltoluene, toluenediamine, in the separation of cresols, and in the separation of polyhydric alcohols such as sugars.
    Type: Grant
    Filed: January 25, 2018
    Date of Patent: June 9, 2020
    Assignees: Arkema France, IFP Energies Nouvelles
    Inventors: Catherine Laroche, Philibert Leflaive, Ludivine Bouvier, Serge Nicolas, Cecile Lutz, Marie-Laurence Labede
