METHOD FOR SEPARATING PARAXYLENES USING AN ADSORBENT FROM THE FAMILY OF ZIFS OF SOD STRUCTURE.

摘要

The invention describes a method for separating paraxylene from an aromatic hydrocarbon feedstock containing isomers with 8 carbon atoms by liquid-phase or gas-phase adsorption. The adsorbent used belongs to the family of ZIFs of SOD structure, containing an inorganic network of metal centres based on Zn2+ cations connected to one another by organic imidazolate ligands substituted in position 2.
