  • Publication number: 20220401914
    Abstract: A binderless zeolite adsorbent for separation of oxygen from a gaseous stream. The adsorbent is a blend of a lithium exchanged zeolite 13X, a lithium exchanged low silica zeolite X zeolite, and halloysite clay. Also disclosed is a process of making the binderless zeolite adsorbent. Further disclosed is a process for production of oxygen from a gaseous stream utilizing the binderless zeolite adsorbent.

  • Patent number: 9486732
    Abstract: Adsorbent compositions useful in adsorption and separation processes are made using silicone-derived binding agents. The adsorbent compositions are made from crystallite aluminosilicate particles bound with silicone-derived binding agents, and optionally small amounts of a clay binder, to form agglomerated crystallite particles and are calcined to volatilize the organic components associated with the silicone-derived binding agents. The agglomerated crystallite particles have superior pore structures and superior crush strengths at low binder concentrations and exhibit enhanced N2 adsorption rates and capacities when used in air separation processes.

  • Patent number: 8680344
    Abstract: A process for the production and use of a molecular sieve blend with improved performance characteristics produced by preparing or obtaining a hydrophilic zeolite, particularly a hydrophilic zeolite 3A with a low SiO2:Al2O3 ratio, preparing or obtaining a hydrophobic silica binder, particularly a hydrophobic colloidal silica, mixing the zeolite with the silica binder to form a mixture, and forming the mixture into the molecular sieve blend.

  • Patent number: 6096194
    Abstract: An adsorbent for organic sulfur compound removal from mineral, vegetable or animal oils useful to protect a hydrogenation catalyst against poisoning, wherein the adsorbent is a zinc-exchanged form of low silica faujasite with a silica to alumina ratio from about 1.8 to about 2.1, wherein the adsorbent contains an inequivalent excess of zinc cations from about 8 to about 20% (equiv.) and a process for manufacture and use of the adsorbent.
