Chemical stability and biodegradability of new solvents for CO2 capture

Chemical Capture of CO2 by Glycine Salt Solution

The role of carbon dioxide in global warming is one of the contemporary environmental issues and it is, therefore, necessary to have available technology to capture the released CO2 into the atmosphere. Amino acids have the same amine functionality as alkanolamines with similar behavior towards CO2 absorption. The solubility of carbon dioxide in potassium glycinate (KG) solutions with different...

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 ...

A computational investigation on the structural features of alkanolamine solvents for CO2 capture process from power plant flue gas

Development of New Potassium Carbonate Sorbent for CO2 Capture under Real Flue Gas Conditions

In this paper, the development of a new potassium carbonateon alumina support sorbent prepared by impregnating K2CO3 with an industrial grade of Al2O3 support was investigated. The CO2 capture capacity was measured using real flue gas with 8% CO2 and 12% H2O in a fixed-bed reactor at a temperature of 65 °C using breakthrough curves. The developed sorbent showed an adsorption capacity of 66.2 mg...
