Pressure Swing Adsorption (PSA) for hydrogen purification using UTSA-16 metal-organic framework
Development of moving bed temperature swing adsorption (MBTSA) process for post-combustion CO2 capture: Initial benchmarking in a NGCC context and design of pilot
Experimental Results of Pressure Swing Adsorption (PSA) for Pre-combustion CO2 Capture with Metal Organic Frameworks
Vacuum Pressure Swing Adsorption (VPSA) has already proved that it can be used for capture of CO2 from the tail gas of the PSA process for hydrogen purification. The demo operated in Port Arthur by Air Products has already captured more than 1 million metric tons of CO2. In this work we are evaluati...
UiO-67-type Metal-Organic Frameworks with Enhanced Water Stability and Methane Adsorption Capacity
The structure and properties of two new UiO-67-type metal–organic frameworks, along with their linker synthesis and powder and single crystal synthesis, are presented. The new MOFs, UiO-67-Me and UiO-67-BN, are based on 3,3′-dimethylbiphenyl and 1,1′-binaphthyl linker scaffolds, and show a much high...
New insights into UTSA-16
Among the metal organic framework materials proposed for CO2 separation, UTSA-16 possesses the highest CO2 volumetric density explained on the basis of favourable interactions between CO2 and structural water molecules in the material, as revealed by neutron diffraction. In this study, UTSA-16 was s...
Adsorption and diffusion of H2, N2, CO, CH4 and CO2 in UTSA-16 metal-organic framework extrudates
Recently, a new metal-organic framework, named UTSA-16, has been proposed for removing carbon dioxide from gas mixtures by pressure swing adsorption in view of its high adsorption capacity and selectivity to this gas. Fundamental adsorption and diffusion parameters are required for designing a press...
An efficient recipe for formulation of metal-organic Frameworks
A method to efficiently formulate metal-organic frameworks (MOFs) is provided. Our approach follows basic rules of extrusion where the elements of extrusion are the MOF (UTSA-16 powder), the binder (poly-vinyl alcohol, PVA) and the plasticizer (water and propanol). The extrudates produced with this ...
A procedure to find thermodynamic equilibrium constants for CO2 and CH4 adsorption on activated carbon
Thermodynamic equilibrium for adsorption means that the chemical potential of gas and adsorbed phase are equal. A precise knowledge of the chemical potential is, however, often lacking, because the activity coefficient of the adsorbate is not known. Adsorption isotherms are therefore commonly fitted...
