carbon dioxide capture by modified uvm-7 adsorbent

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...

Investigation of Adsorbent - based Warm Carbon Dioxide Capture Technology for IGCC System

Integrated gasification combined cycle with CO 2 capture and sequestration (IGCC-CCS) emerges as one of the most promising technologies for reducing CO 2 emission from coal power plant without reducing thermal efficiency significantly. However the high capital cost of these plants has limited their deployment. The current solvent-based low-temperature CO 2 capture process (Selexol process) is e...

Carbon dioxide capture and sequestration

Carbon Capture Using Amine-modified Carbon Nanotubes

The increasing rise in the rate of both anthropogenic CO2 emissions and atmospheric CO2 concentration, combined with an evolving understanding of what this means for global climate change both now, and in the future, has increased the need for novel technologies for CO2 capture from large point sources. Current industry standards involve the use of amine solvents, which have a large parasitic l...

Carbon Dioxide Capture by Chemical Absorption: A Solvent Comparison Study

In the light of increasing fears about climate change, greenhouse gas mitigation technologies have assumed growing importance. In the United States, energy related CO2 emissions accounted for 98% of the total emissions in 2007 with electricity generation accounting for 40% of the total. Carbon capture and sequestration (CCS) is one of the options that can enable the utilization of fossil fuels ...

Reversible, solid state capture of carbon dioxide by hydroxylated amidines.

Hydroxylated amidine derivatives can capture, store, and release CO(2) reversibly in the solid state in a quantitative manner under clean and dry conditions at ambient temperature.
