  • Patent number: 10677160
    Abstract: Systems and methods are provided for combined cycle power generation while reducing or mitigating emissions during power generation. Recycled exhaust gas from a power generation combustion reaction can be separated using a swing adsorption process so as to generate a high purity CO2 stream while reducing/minimizing the energy required for the separation and without having to reduce the temperature of the exhaust gas. This can allow for improved energy recovery while also generating high purity streams of carbon dioxide and nitrogen.

  • Publication number: 20200101439
    Abstract: Methods of synthesizing crystalline metal-organic frameworks (MOFs) comprising polytopic organic linkers and cations, where each linker is connected to two or more cations, are provided. In the disclosed methods, the linkers are reacted with a compound of formula MnXm, where M is cationic Be, Mg, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Zr, Nb, Mo, Ru, Rh, Pd, Cd, or Hf, X is anionic, n and m are integers. The reacting is buffered by a buffer devoid of metal coordinating functionality when the pKa of the anion is below a threshold related to the lowest pKa of the linker. The reacting is optionally not buffered when the pKa of the anion is at or above this threshold. The disclosed methods lead to product phase MOF in which crystal growth is controlled leading to control over molecular diffusion.

  • Publication number: 20190126237
    Abstract: Polyamines with lengths carefully tailored to the framework dimensions are appended to metal-organic frameworks such as Mg2(dobpdc) (dobpdc4-=4,4?-dioxidobiphenyl-3,3?-dicarboxylate) with the desired loading of one polyamine per two metal sites. The polyamine-appended materials show step-shaped adsorption and desorption profiles due to a cooperative CO2 adsorption/desorption mechanism. Several disclosed polyamine-appended materials exhibit strong ability to capture CO2 from various compositions. Increased stability of amines in the framework has been achieved using high molecular weight polyamine molecules that coordinate multiple metal sites in the framework. The preparation of these adsorbents as well as their characterization are provided.
