Advance in Post-Combustion CO2 Capture with Alkaline Solution: A Brief Review

APTES grafted ordered mesoporous silica KIT-6 for CO2 adsorption

“…CCS is important to mitigate the global warming and its consequences by capture of CO 2 from large anthropogenic sources. Aqueous alkanolamines and chilled ammonia based absorption process [5,6], membrane separation process [7,8], novel cryogenic process [9], algal biomass process [10,11] and porous solid adsorption process [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29] are most commonly used for CO 2 capture. Among these processes aqueous alkanolamine especially monoethanolamine (MEA) and diethanolamine (DEA) based absorption process is well known with significant commercial application for CO 2 capture.…”

Optimal Absorbent Evaluation for the CO2Separating Process by Absorption Loading, Desorption Efficiency, Cost, and Environmental Tolerance

“…In chemical absorption, an alkaline absorbent is used to capture CO 2 by acid-base reaction. Traditionally alkanolamines, such as monoethanolamine (MEA) and tri-ethanolamine (TEA), have been used in industries for several years to remove acid gases such as CO 2 and H 2 S (Abu-Arabi, Tamimi, Al-Jarrah 2001; Alie et al 2005;Peng, Zhao, Li 2012). However, there are some disadvantages, such as corrosiveness and heat demand, of using alkanolamines to capture CO 2 .…”

Chemical absorption and CO2 biofixation via the cultivation of Spirulina in semicontinuous mode with nutrient recycle

“…In the contemporary period, different strategies are employed in an attempt to reduce and stabilize CO 2 concentrations. These strategies include the use of renewable energy, chemical processes, such as chemical absorption (Peng et al, 2012) and biological processes such as photosynthesis microalgae.…”
