  • Patent number: 7595275
    Abstract: The present invention relates to molecular sieve compositions and a process to synthesize such compositions. More particularly, this invention relates to a catalyst composition with metal oxide deposited on the exterior surface of the molecular sieve particles. The metal oxide can be deposited by contacting the molecular sieve particles with a solution of a metal-containing salt and a solvent, the metal-containing salt solution having an anion size larger than the pore size of the molecular sieve particles. The molecular sieve particles can then be dried and then treated under conditions sufficient to form a metal oxide, whereby at least a portion of the metal-containing salt can be converted to metal oxide.

  • Patent number: 7592284
    Abstract: A high capacity adsorbent may be used for enriching oxygen concentration in an air stream. Such a high capacity adsorbent may be from about 2 to about 3 times lighter relative to the currently available technology. Furthermore, the high capacity adsorbent is readily capable of regeneration after deactivation by water vapor. Unlike current available immobilization technology in which clay binder was used to bind 13X zeolite and additional 10% organic binder was used to immobilize beads, the adsorbents of the present invention may be made using just an organic binder, thereby reducing pore spoilage caused by the clay binder. Further unlike conventional adsorbents, which may use sodium as its cation, the adsorbent of the present invention uses a lithium cation, thereby resulting in enhanced nitrogen adsorption performance.

  • Patent number: 6780806
    Abstract: The invention provides new methods for separating nitrogen from a mixture. The invention provides adsorbents specifically for accomplishing nitrogen separation. The adsorbents and separation methods are particularly useful for the selective adsorption of nitrogen from air. In one aspect, the adsorbent comprises an ion exchange zeolite X and preferably zeolite LSX (low silica zeolite X). The zeolite is most preferably a lithium-based zeolite. Further, the zeolite has exchangeable cationic sites, with silver cation or copper cation occupying at least some of the exchangeable cationic sites. The Ag/Cu exchanged zeolite is heat-treated under specific conditions as per the invention. The presence of the silver cation or copper cation at any of the sites will provide an improvement over the non-exchanged zeolite.
