Abstract: Metal organic resins, composite materials composed of the metal organic resins, and anion exchange columns packed with the composite materials are provided. Also provided are methods of using the composite materials to remove metal anions from a sample, methods of using the metal organic resins as fluorescence sensors for detecting metal anions in a sample, and methods of making the metal organic resins and the composite materials. The metal organic resins are amine-functionalized metal organic frameworks and their associated counter anions. The composite materials are composed of metal organic resin particles coated with organic polymers, such as alginic acid polymers.

Abstract: The present invention relates to methods of preferentially sorbing, from a target mixture, one or more target substance(s) over one or more non-target substance(s). In particular, porous organic cages (POCs) may be deployed in the quantum sieving of mixtures of hydrogen isotopes to selectively sorb heavy hydrogen isotopes (e.g. diatomic deuterium) over lighter isotopes (diatomic protium).

Abstract: A natural gas pretreatment system includes: a carbon dioxide removal unit configured to remove carbon dioxide from the natural gas by bringing an absorption liquid and the natural gas into contact with each other; and a water removal unit configured to remove water by causing the natural gas to flow through a packed bed containing a water adsorbent. The packed bed contains a carbon dioxide adsorbent for adsorbing and removing the carbon dioxide that has not been completely removed in the carbon dioxide removal unit, and a concentration of the carbon dioxide contained in the natural gas is measured by an outlet-side carbon dioxide measurement unit on an outlet side of the water removal unit.

Abstract: Systems and methods for an atmospheric carbon dioxide removal system are disclosed herein. The system may include a carbon capture vessel including a container, one or more sorbent subcontainer, a sorbent material, and a heating element. The container may include a first outer sidewall and a first hollow interior. Each sorbent subcontainer may be disposed within the first hollow interior and may include a second outer sidewall defining a second hollow interior. The sorbent material may be disposed within the second hollow interior of each sorbent subcontainer. The heating element may be disposed within the container and around one or more sidewalls of a sorbent subcontainer. The heating element may be arranged to heat the sorbent material within the second hollow interior.

Abstract: A method comprising contacting an offgas stream comprising H2, H2O, CO, CO2, and at least one impurity comprising COS with at least one metal oxide to catalyze a reaction of H2O and COS to form H2S and CO2 in the offgas stream; contacting the offgas stream with an H2S-adsorbent to remove H2S from the offgas stream to produce a treated gas stream; and separating the treated gas stream to produce a carbon dioxide-enriched stream and a carbon dioxide-depleted stream.

Abstract: A system and method for, removing carbon dioxide from a carbon dioxide laden gas mixture, the system comprising a group of carbon dioxide removal structures moving along a closed curve track. At one location along the track is located a desorption or regeneration box, into which each capture structure passes in order to be regenerated. The majority of the CO2 removal structures are fed ambient air, or an admixture of ambient air with a minor portion of a flue gas, and exhaust CO2-lean air. At least one selected such removal structure within each group, at a location immediately preceding its entry into the capture structure, is fed a flue gas comprising at least 4% CO2 by volume. A method for removing carbon dioxide from the atmosphere is provided utilizing a system operating in the same manner as the preceding system.

Abstract: The invention comprises a process for remediation of soil comprising PFAS. The process comprises steps a)-d). In step a) sludge and a first gaseous stream are heated in a first spouting bed incinerator, thereby generating a raw material for a ceramic article and a first gaseous stream comprising a first flue gas, the first gaseous stream comprising the first flue gas having a temperature of at least 800° C. In step b) the first gaseous stream comprising the first flue gas is heat exchanged with a second gaseous stream in an air-to-air heat exchanger, thereby generating a second gaseous stream with a temperature of at least 500° C. In step c) the soil comprising PFAS is contacted with the second gaseous stream in a dryer, thereby evaporating the PFAS from the soil and generating clean soil and a second gaseous stream comprising PFAS. In step d) the second gaseous stream comprising PFAS is further heated to a temperature of at least 1000° C. in a second spouting bed incinerator, thereby generating a second gaseous stream comprising destructed PFAS.
