  • Patent number: 9914111
    Abstract: The present invention relates to a mercury-containing wastewater treatment technology field, in particular to an attapulgite-crosslinked chitosan composite adsorbent and its solid-phase synthetic method. The attapulgite-crosslinked chitosan composite mercury adsorbent in the invention is synthesized by the method of adding chitosan and glutaraldehyde in batches. In consideration of the limited solubility of chitosan, batch addition can not only dissolve chitosan, but also minimize the use of organic acid, resulting in less discharge of wastewater and waste gas, which is suitable for large-scale industrial production. The prepared mercury adsorbent can be applied to the removal of mercury ions in the wastewater owing to the excellent adsorptive property and regeneration performance. Meanwhile, the solid-phase synthetic procedure for preparing the mercury adsorbent is simple, easy to handle and environmental-friendly. Moreover, the product cost is greatly reduced due to the use of attapulgite.

  • Patent number: 9376641
    Abstract: A 3D porous metal-organic framework and method of making are described. In some embodiments, a 3D porous metal-organic framework may be based on a trinodal (3,3,4) net of zyg topology by the self-assembly of the nonlinear hexacarboxylate (BHB) with the paddle-wheel Cu2(COO)4 cluster. Although its porosity and surface area are moderate, the open copper sites and optimal pore spaces enable the pore spaces to be fully utilized for methane storage, resulting in a high methane storage density and high absolute volumetric methane storage at room temperature and 35 bar. By the immobilization of high density open metal sites and the deliberate control of the pore space for their efficient methane storage, this porous MOF functions as an efficient media for methane and natural gas storage.

  • Patent number: 9186626
    Abstract: Methods are provided for removing CO2 and/or H2S from a gas phase stream, such as a refinery flue gas stream, a coal-fired or petroleum-burning power plant, or a natural gas stream. A gas phase stream containing CO2 and/or H2S can be contacted under effective conditions with an aqueous slurry of supported amine particles. The CO2 and/or H2S can react with the supported amines to form bicarbonates, carbonates, carbamates, sulfide salts, or other species. Because the amine is part of, bonded to, or otherwise supported on a particulate substrate, the reaction product from the amine reaction can also remain bound to the particle. After reacting supported amines with CO2 and/or H2S captured from a gas stream, the supported amines particles can be separated from the aqueous slurry environment for regeneration of the supported amine and release of the CO2 and/or H2S.

  • Publication number: 20150144831
    Abstract: Biogenic activated carbon compositions disclosed herein comprise at least 55 wt % carbon, some of which may be present as graphene, and have high surface areas, such as Iodine Numbers of greater than 2000. Some embodiments provide biogenic activated carbon that is responsive to a magnetic field. A continuous process for producing biogenic activated carbon comprises countercurrently contacting, by mechanical means, a feedstock with a vapor stream comprising an activation agent including water and/or carbon dioxide; removing vapor from the reaction zone; recycling at least some of the separated vapor stream, or a thermally treated form thereof, to an inlet of the reaction zone(s) and/or to the feedstock; and recovering solids from the reaction zone(s) as biogenic activated carbon. Methods of using the biogenic activated carbon are disclosed.

  • Publication number: 20150136700
    Abstract: The present invention provides a chromatographic stationary phase material various different types of chromatography. One example chromatographic stationary phase is represented by Formula 1 [X](W)a(Q)b(T)c (Formula 1). X can be a high purity chromatographic core composition. W can be absent and/or can include hydrogen and/or can include hydroxyl on the surface of X. Q can be bound directly to X and can include a first hydrophilic, polar, ionizable, and/or charged functional group that chromatographically interacts with the analyte. T can be bound directly to X and can include a second hydrophilic, polar, ionizable, and/or charged functional group that chromatographically interacts with the analyte. Additionally, Q and T can essentially eliminate chromatographic interaction between the analyte, and X and W, thereby minimizing retention variation over time (drift or change) under chromatographic conditions utilizing low water concentrations.
