Carbon dioxide capture using monoethanolamine in a microchannel

Toward carbon dioxide capture using nanoporous materials*

The development of more efficient processes for CO2 capture from the flue streams of power plants is considered a key to the reduction of greenhouse gas emissions implicated in global warming. Indeed, several U.S. and international climate change initiatives have identified the urgent need for improved materials and methods for CO2 capture. Conventional CO2 capture processes employed in power p...

Carbon Dioxide Capture by Modified UVM-7 Adsorbent

In this study, bimodal meso-porous silica (UVM-7) synthesized and fabricated amino silane modified supports were characterized by powder X-ray diffraction (XRD), N2 adsorption/desorption, transmission electron microscope (TEM), elemental analysis and titration. Capacity of CO2 capture on modified bimodal pore structure silica at 70°C was calculated using breakthrough curves; and it was found th...

Carbon dioxide capture and sequestration

Carbon dioxide capture in metal-organic frameworks.

Efforts to utilize metal-organic frameworks, a new class of materials exhibiting high surface areas, tunable pore dimensions, and adjustable surface functionality, for CO2 capture will be presented. Open metal coordination sites on the framework surface can deliver a high CO2 loading capacity at low pressures. However, additional criteria such as water stability and the selective binding of CO2...

Carbon dioxide capture using amine functionalized silica gel

Commercially available silica gel is chemically modified for carbon dioxide capture. Calcinated silica gel of certain particle size functionalized with amine using two different methods, wet impregnation and grafting via silane chemistry has been employed as a porous media. The prepared material is characterized by Fourier transform infrared, scanning electron microscopy, energy dispersive anal...
