Cyclical method of producing high-purity nitrogen and optionally a high-purity hydrocarbon from a feedstock containing nitrogen and a hydrocarbon
The invention relates to a cyclical method for producing a nitrogen fraction, the purity of which is greater than or equal to 95 mol %, and a hydrocarbon-enriched fraction from a filler containing nitrogen and a hydrocarbon, said method using a specific class of porous hybrid solids as an adsorbent in a pressure-swing adsorption (PSA) process. The invention also relates to equipment for implementing said method.

Disclosed herein is a metal organic framework (MOF) having a UTSA-16 structure, where the composition comprises: from 0 to 80 mol % of the total metal in the MOF is a first metal selected from one or more of the group consisting of Cr, Mn, Fe, Ni, Cu, and Co; and from 20 to 100 mol % of the total metal in the MOF is a second metal selected from one or more of the group consisting of Cd, Mn, and Zn.
COMPOSITIONS AND METHODS FOR THE LIQUID-PHASE SEPARATION OF ISOMERS OF AROMATIC MOLECULES
The present invention includes a composition and process for separating p-isomers of vinylbenzenes from a mixture of isomers comprising the steps of: providing a porous microwaved Mg(II) 2,4-pyridinedicarboxylic acid coordination polymer having a 1-D pore structure and showing reversible soft-crystal behavior by preferentially binding p-isomers of vinylbenzene; adding a mixture of vinylbenzenes isomers to the porous microwaved Mg (II) 2,4-pyridinedicarboxylic acid coordination polymer; adsorbing the p-isomers of vinylbenzene from the mixture of vinylbenzenes isomers; selectively adsorb the p-isomers of vinylbenzene in the 1-D pore structure; removing the mixture of vinylbenzenes isomers; and desorbing the p-isomers of vinylbenzene from the 1-D pore structure to purify the p-isomers of vinylbenzene.
MATERIAL AND METHOD FOR CARBON DIOXIDE FIXATION
[Problem] To provide a new way for fixing carbon dioxide under mild conditions and with high efficiency.
[Solution] The material for carbon dioxide fixation according to the present invention contains a metal ion donor and an amine as a precursor of a bridging ligand. The amine is configured to react with a gaseous carbon dioxide to form the bridging ligand having at least one carbamate anion moiety. The bridging ligand is configured to react with the metal ion donor to form a coordination polymer in which a plurality of the metal ions is linked by the bridging ligand.
Sorbent structures with resistive heating capability and methods of making the same
A sorbent structure that includes a continuous body in the form of a flow-through substrate comprised of at least one cell defined by at least one porous wall. The continuous body comprises a sorbent material carbon substantially dispersed within the body. Further, the temperature of the sorbent structure can be controlled by conduction of an electrical current through the body.
Multivariate metal-organic frameworks for fine-tuning light emission
Multivariate metal-organic framework compositions and methods of producing multivariate metal-organic frameworks. The metal-organic framework including at least one light-emitting linker in an amount sufficient for the composition to produce broadband emission spectra in high efficiencies.
Water stable copper paddlewheel metal organic framework (MOF) compositions and processes using the MOFs
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.
METHOD FOR GAS SEPARATION
A method for separating at least one hydrocarbon from a feed containing a mixture of at least one hydrocarbon and nitrogen, comprising contacting the feed with an adsorbent comprising a porous support wherein the porous support comprises exchangeable cations and at least a portion of the exchangeable cations are organic cations.
Covalent Organic Frameworks
Chemically and thermally stable covalent organic framework (COF) materials are configured and operative as solid adsorbents for capturing gases and water.
MULTIMETAL-METAL ORGANIC FRAMEWORK ADSORBENT
Mixed metal metal-organic frameworks (MM-MOFs) of copper-1,3,5-benzenetricarboxylate (BTC), M-Cu-BTC, wherein M is Zn(II), Ni(II), Co(II), and/or Fe(II) may be made using post-synthetic exchange (PSE) with metal ions. Such MM-MOFs may be used in H.sub.2 storage, especially Ni(II) and Co(II) MM-MOFs. Selected metal exchanged materials can provide gravimetric H.sub.2 uptake around 1.63 wt. % for Zn—Cu-BTC, around 1.61 wt. % for Ni—Cu-BTC, around 1.63 wt. % for Fe—Cu-BTC, and around 1.12 wt. % for Co—Cu-BTC.
