Advantaged adsorption contactors

Metal-organic framework materials (MOFs) are highly porous entities comprising a multidentate organic ligand coordinated to multiple metal centers, typically as a coordination polymer. Crystallization may be problematic in some instances when secondary binding sites are present in the multidentate organic ligand. Multidentate organic ligands comprising first and second binding sites bridged together with a third binding site comprising a diimine moiety may alleviate these issues, particularly when using a preformed metal cluster as a metal source to form a MOF. Such MOFs may comprise a plurality of metal centers, and a multidentate organic ligand coordinated to the plurality of metal centers to define an at least partially crystalline network structure having a plurality of internal pores, and in which the multidentate organic ligand comprises first and second binding sites bridged together with a third binding site comprising a diimine moiety. Particular MOFs may comprise N,N'-di(1H-pyrazol-4-yl)ethane-1,2-diimine as a multidentate organic ligand.

Methods of synthesizing and recycling metal-organic framework systems

The present application relates to absorbents comprising tetraamine ligands grafted onto metal-organic frameworks and a method for using same for CO2 capture from fossil fuel combustion sources to reduce emissions. In particular, this application relates to capturing >90% by volume, preferable >99% by volume, CO2 emissions such that the emissions are negative, essentially removing CO2 from the combustion air.

Metal-organic frameworks for carbon dioxide capture

Primary, secondary (1&#xb0;,2&#xb0;) alkylethylenediamine- and alkylpropylenediamine-appended variants of metal-organic framework are provided for COcapture applications. Increasing the size of the alkyl group on the secondary amine enhances the stability to diamine volatilization from the metal sites. Two-step adsorption/desorption profiles are overcome by minimzing steric interactions between adjacent ammonium carbamate chains. For instance, the isoreticularly expanded framework Mg(dotpdc) (dotpdc=4,4&#x2033;-dioxido-[1,1':4&#x2032;,1&#x2033;-terphenyl]-3,3&#x2033;-dicarboxylate), yields diamine-appended adsorbents displaying a single COadsorption step. Further, use of the isomeric framework Mg-IRMOF-74-II or Mg(pc-dobpdc) (pc-dobpdc=3,3-dioxidobiphenyl-4,4-dicarboxylate, pc=para-carboxylate) also leads to a single COadsorption step with bulky diamines. By relieving steric interactions between adjacent ammonium carbamate chains, these frameworks enable step-shaped COadsorption, decreased water co-adsorption, and increased stability to diamine loss. Variants of Mg(dotpdc) and Mg(pc-dobpdc) functionalized with large diamines such as N-(n-heptyl)ethylenediamine have utility as adsorbents for carbon capture applications.

Use of Type V adsorbent and gas concentration for gas adsorption and capture

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 MX, 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.

Metal-organic framework phase and crystallite shape control

Polyamines with lengths carefully tailored to the framework dimensions are appended to metal-organic frameworks such as Mg(dobpdc) (dobpdc4-=4,4'-dioxidobiphenyl-3,3&#x2032;-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 COadsorption/desorption mechanism. Several disclosed polyamine-appended materials exhibit strong ability to capture COfrom 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.
