  • Adsorbent granulate and method for the manufacture thereof
    Patent number: 9682361
    Abstract: The invention relates to a X-zeolite based adsorbent granulate with faujasite structure and a molar SiO2/Al2O3 ratio of ?2.1-2.5, wherein the granulate has an average transport pore diameter of >300 nm and a negligible fraction of meso-pores and wherein the mechanical properties of the granulate are at least the same as or better than the properties of an X-zeolite based granulate formed using an inert binder and the equilibrium adsorption capacities for water, CO2 and nitrogen are identical to those of pure X-zeolite powder with a similar composition.
    Type: Grant
    Filed: December 2, 2013
    Date of Patent: June 20, 2017
    Assignee: CHEMIEWERK BAD KOSTRITZ GMBH
    Inventors: Alfons Brandt, Jens Schmeisser, Baldur Unger, Hartmut Tschritter, Uwe Henkel, Gojdár Bálint, Dietmar Gruhle, Georg Winterstein

  • Method of manufacture of multicationic molecular sieves
    Patent number: 6407025
    Abstract: Zeolites exchanged with lithium cations and polyvalent cations are prepared by first partially ion-exchanging a sodium-containing zeolite, a potassium-containing zeolite or a sodium- and potassium-containing zeolite with polyvalent cations, then heat-treating the partially polyvalent cation-exchanged zeolite, then ion exchanging the heat-treated zeolite with ammonium cations, and then reacting the ammonium cation-exchanged zeolite with a water-soluble lithium compound under conditions which result in the removal of ammonia from the reaction zone.
