  • Patent number: 11958033
    Abstract: This invention relates to modified MOF materials, methods of preparing them and processes using them. A modified MOF of the invention is modified by impregnating a MOF with an inorganic metal salt. The starting MOF contains at least one linker or ligand which contains an aryl amino group as part of its structure. These modified MOFs are able to adsorb either basic or acidic toxic industrial compounds (TIC). The modified MOFs can be used to remove TICs from various gaseous streams such as air.

  • Patent number: 11958034
    Abstract: This invention relates to metal organic framework (MOF) compositions, methods of preparing them and methods of using them. The MOF compositions are characterized in that at least a portion of the linker molecule is an amino containing organic linker. The MOF also has a crystal size of greater than 1 ?m and has been treated with an acid wash to provide a MOF in which at least 55% of the amino groups are activated amino groups of the form —NH2. The MOF compositions are useful in adsorbing various contaminants from various gas stream. One specific example is adsorbing NO2 from an air stream.

  • Publication number: 20230381729
    Abstract: A spin contactor is provided for contacting a particulate with a fluid. The spin contactor has a containment section that may contain the particulate, a fluid inlet, and a fluid outlet. The containment section comprises an upper particulate separator, a lower particulate separator, and a conical wall. In most cases, the spin contactor includes a shaft to be operatively coupled to a means for spinning the spin contactor. The fluid is drawn upwardly through the fluid inlet to contact the particulate and then expelled through the fluid outlet. A process of treating a fluid composition is provided by sending the fluid composition through the spin contactor comprising particulates.

  • Patent number: 11679373
    Abstract: This invention relates to a Cu-BTC MOF which is water stable. The Cu-BTC MOF has been modified by substituting some of the BTC ligand (1,3,5, benzene tricarboxylic acid) with 5-aminoisophthalic acid (AIA). The resultant MOF retains at least 40% of its as synthesized surface area after exposure to liquid water at 60° C. for 6 hours. This is an unexpected result versus the MOF containing only the BTC ligand. This MOF can be used to abate contaminants such as ammonia in gas streams and especially air streams.

  • Patent number: 11642650
    Abstract: This invention relates to a method of using MOF adsorbents to remove elemental impurities from feed streams comprising active pharmaceutical ingredients (API). The process involves contacting the feed stream comprising API and elemental impurities with the MOF at purification conditions to obtain a purified stream with provides an API which has a concentration of the elemental impurity below its permitted daily exposure. The process can be carried in a batch mode where the MOF and feed stream are admixed in a vessel for a given amount of time or continuously by flowing the feed stream through a column or adsorbent bed containing the MOF adsorbent.

  • Patent number: 11285456
    Abstract: This invention relates to a Cu-BTC MOF which is water stable. The Cu-BTC MOF has open coordination sites and has been post synthesis modified by partially occupying the open sites with a ligand such as acetonitrile (CH3CN). The resultant MOF retains at least 40% of its as synthesized surface area after exposure to liquid water at 60° C. for 6 hours. This is an unexpected result versus the MOF which has not been post treated with ligands such as acetonitrile. This MOF can be used to abate contaminants such as ammonia in gas streams and especially air streams.

  • Patent number: 10940426
    Abstract: A method of adsorbing a highly reactive gas onto an adsorbent material comprising adsorbing the highly reactive gas to the adsorbent material. The adsorbent material comprises at least one Lewis basic functional group, or pores of a size to hold a single molecule of the highly reactive gas, or inert moieties which are provided to the adsorbent material at the same time at the same time as the highly reactive gas, prior to adsorbing the highly reactive gas or after adsorbing the highly reactive gas, or the highly reactive gas reacts with moieties of the adsorbent material resulting in passivation of the adsorbent material. A rate of decomposition of the adsorbed highly reactive gas is lower than a rate of decomposition for the neat gas at equal volumetric loadings and equal temperatures for both the adsorbed highly reactive gas and the neat gas.

  • Publication number: 20210048148
    Abstract: A valve assembly and process are disclosed that permit charging and dispensing gas from a storage vessel through one passage and one nozzle. Only one passage is in communication with the pressurized gas in the storage vessel which focuses safety measures on a single passage. Gas is passed through a single regulator to dispense gas from the storage vessel and to charge the storage vessel. The regulator utilizes a diaphragm which when pressurized by a separate fluid permits passage through the regulator. This separate fluid does not have access to the interior of the storage vessel.
