    摘要: Zeolites exchanged with lithium, caesium or rubidium cations and polyvalent cations (e.g. pure earths or Group III cation) 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.

    摘要: The present invention provides for novel solid state O 2 -selective metal complex-based adsorbents and their utility for separating oxygen from a gas stream. In particular, the invention provides for an adsorption complex which contains four-coordinate O 2 -selective metal complexes including oligomeric/polymeric metal complexes, and organic base-containing polymers supported on porous materials. Examples of adsorbents according to the invention include (i) a composition of poly (4-vinylpyricline-co-styrene) and bis (3,5-di- tert -butylsalicylidene)-1,2- (1,2-dicyanoacetylene) diamino cobalt ((II) and (ii)) a composition of poly (4-vinylpyricline- co -styrene), silica gel, and bis (salicylidene)-12-ethylenediaminocobalt (II)

    摘要: Zeolites exchanged with lithium ions and, optionally, with polyvalent cations are prepared by ion-exchanging a sodium-containing zeolite, a potassium-containing zeolite or a sodium- and potassium-containing zeolite with ammonium ions, thereby replacing the sodium and/or potassium ions with ammonium ions, and then reacting the ammonium ion-exchanged zeolite with a water-soluble lithium compound under conditions which result in the removal of ammonia from the reaction zone. Polyvalent ions, which may be present in the zeolite undergoing ion-exchange, will not be substantially replaced by the ammonium or lithium ions.

    摘要: An improved method for preparing various sorbent shapes such as beads for use in gas separation processes is disclosed. Highly siliceous nanoporous materials in their crystalline powder form are stabilized by thermal pretreatment prior to their contact with a mineral binder. The resulting sorbent shapes maintain their crystalline structure particularly when the pH value of the mineral binder in its aqueous suspension is greater than 10. The sorbent beads that result from this process, are especially suitable for the separation of gaseous low-molecular-weight hydrocarbons such as paraffins, olefins, and their mixtures from carbon dioxide in wet atmospheres.
