The latest development on amine functionalized solid adsorbents for post-combustion CO2 capture: Analysis review

CO2 adsorption on PEHA-functionalized geothermal silica waste: a kinetic study and quantum chemistry approach

“…Efforts to reduce the CO 2 capture cost involve the development of new and more energy-efficient technologies such as solid adsorption. 2…”

“…The amine in this method diffuses into the pore space of the support: zeolites, silica, carbon-based materials, MOFs, 15–19 and even waste materials such as coal fly, wood, and rice ashes. 2,20,21 Besides, it is critical to properly select the amine or mixture of amines (polymeric or oligomeric). Factors like toxicity, reactivity, chain length, stability, and even cost are essential when choosing the amine.…”

“…Monoethanolamine (MEA), polyethyleneimine (PEI), tetraethylenepentamine (TEPA), diethylenetriamine (DETA), triethylenetetramine (TETA), and pentaethylenehexamine (PEHA) are the typical amines used for the CO 2 capture process. 2,5,9,11,13,22 Among them, given their high stability and nitrogen content, PEI, TEPA, and recently PEHA are the most widely used amine species (Table 1). 2 Wei et al reported the preparation of SBA-15 with a loading of 50 wt% of PEHA, which showed a capture capacity of 154 mg CO2 g −1 at 80 °C.…”

Enhancement of carbon dioxide adsorption performances by hydrazinolysis of poly(n-vinylformamide) grafted fibrous adsorbent

“…The emission of greenhouse gases is generated from anthropogenic activities include burning of fossil fuels, production of electricity, agricultural practices, transportation and manufacturing. At present, carbon capture and sequestration (CCS) is considered as one of the most promising solutions to mitigate the CO2 emissions [1,2]. There are three methods for CCS: precombustion capture, oxy-fuel process, and post-combustion capture.…”
