Technoeconomic perspectives on sustainable CO2 capture and utilization

Integrated CO2 Capture and Utilization Using Non-Thermal Plasmolysis

In this work, two simple processes for carbon dioxide (CO2) such as capture and utilization have been combined to form a whole systems approach to carbon capture and utilization (CCU). The first stage utilizes a pressure swing adsorption (PSA) system, which offers many benefits over current amine technologies. It was found that high selectivity can be achieved with rapid adsorption/desorption t...

Sustainable porous carbons with a superior performance for CO2 capture

Sustainable porous carbons have been prepared by chemical activation of hydrothermally carbonized polysaccharides (starch and cellulose) and biomass (sawdust). These materials were investigated as sorbents for CO2 capture. The activation process was carried out under severe (KOH/precursor=4) or mild (KOH/precursor=2) activation conditions at different temperatures in the 600-800oC range. Textur...

Functionalized Polymeric Membranes for CO2 Capture

Reducing CO2 emission and lowering the concentration of greenhouse gases in the atmosphere has quickly become one of the most urgent environmental issues. While a variety of technologies and methods have been developed, the separation of CO2 from gas streams is still a critical issue. Apart from establishing new techniques, the exploration of membrane materials with high separation performance ...

Advanced Solvent for CO2 Capture and Separation Technology for CO2 Sequestration to Enhance Utilization and Reduce Emissions from Wyoming Coal

Low transition temperature mixtures as innovative and sustainable CO2 capture solvents.

The potential of three newly discovered low transition temperature mixtures (LTTMs) is explored as sustainable substituents for the traditional carbon dioxide (CO2) absorbents. LTTMs are mixtures of two solid compounds, a hydrogen bond donor (HBD) and a hydrogen bond acceptor (HBA), which form liquids upon mixing with melting points far below those of the individual compounds. In this work the ...
