Efficient CO2 capture by tertiary amine-functionalized ionic liquids through Li+-stabilized zwitterionic adduct formation
Highly efficient CO2 absorption was realized through formation of zwitterionic adducts, combining synthetic strategies to ionic liquids (ILs) and coordination. The essence of our strategy is to make use of multidentate cation coordination between Li(+) and an organic base. Also PEG-functionalized organic bases were employed to enhance the CO2-philicity. The ILs were reacted with CO2 to form the...
متن کاملStructure and Activity Relationships for CO2 Regeneration from Aqueous Amine Based Absorbents
A study to determine the structure and activity relationships of various amine based CO2 absorbents was performed in which, the desorption of CO2 from saturated absorbent at 80 C and atmospheric pressure was measured to assess the initial desorption rate and desorption capacities at pseudo equilibrium. Evaluation of desorption capacity at 80 C will give a better understanding for more energy ef...
متن کاملFunctionalized 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 ...
متن کاملDevelopment 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...
متن کاملEffect of amine structure on CO2 capture by polymeric membranes
Poly(amidoamine)s (PAMAMs) incorporated into a cross-linked poly(ethylene glycol) exhibited excellent CO2 separation properties over H2. However, the CO2 permeability should be increased for practical applications. Monoethanolamine (MEA) used as a CO2 determining agent in the current CO2 capture technology at demonstration scale was readily immobilized in poly(vinyl alcohol) (PVA) matrix by sol...
