“…A peak at around ~1470 cm -1 attributed to C-H bending vibration; a peak at around ~1550 cm -1 assigned to N-H or NH 2 bending [26,27], and a band appeared at around ~1315 cm -1 also assigned to presence of amine groups, start to increase as the weight percent of TEPA increased. The appearance of the peaks at around ~2850 cm -1 and ~2950 cm -1 assigned to the stretching vibration of C-H associated with TEPA start to appear and increase gradually as the weight percent of TEPA increased [28].…”

“…An efficient alternative method for CO 2 removal is the adsorption of CO 2 onto a porous solid sorbent, due to its ease of handling and low energy consumption for regeneration. Porous sorbents with amine-functionalization, such as zeolites [3], silicas [4,5], activated carbons [6], and polymers [7], have been investigated for their adsorption performance. It has been found that the pore structure, type of amine, number of active sites, and the operating condition have a significant influence on the CO 2 adsorption capacity of the sorbent.…”

The synthesis of carbon nanoparticles (Cn) and oxygen-doped nanocarbon (OCn) was successfully done through a one-step synthesis by the solution plasma process (SPP). The Cn and OCn were nitrogen-doped by nitridation under an ammonia atmosphere at 800 • C for 2 h to yield NCn and NOCn, respectively, for carbon dioxide (CO 2 ) adsorption. The NOCn exhibited the highest specific surface area (~570 m 2 g −1 ) and highest CO 2 adsorption capacity (1.63 mmol g −1 at 25 • C) among the synthesized samples. The primary nitrogen species on the surface of NOCn were pyridinic-N and pyrrolic-N. The synergistic effect of microporosity and nitrogen functionality on the NOCn surface played an essential role in CO 2 adsorption enhancement. From the thermodynamic viewpoint, the CO 2 adsorption on NOCn was physisorption, exothermic, and spontaneous. The NOCn showed a more negative enthalpy of adsorption, indicating its stronger interaction for CO 2 on the surface, and hence, the higher adsorption capacity. The CO 2 adsorption on NOCn over the whole pressure range at 25-55 • C best fitted the Toth model, suggesting monolayer adsorption on the heterogeneous surface. In addition, NOCn expressed a higher selective CO 2 adsorption than Cn and so was a good candidate for multicycle adsorption.

“…As a result, there has been a strong interest to develop alternative more stable and less energy-intensive CO 2 removal technologies. Adsorption using solid sorbents [6][7][8][9], particularly amine-functionalized sorbents, is appealing due to their potentially lower energy requirements for sorbent regeneration [1,2,[10][11][12][13][14][15][16][17][18][19][20][21][22]. By immobilizing amine functionalities on high-surface porous solid supports, the amino solid sorbents offer higher amine efficiency and thus superior sorbent performance [18,19,23,24].…”

A thorough and comprehensive study of different parameters affecting the sorbents prepared by impregnating polyethyleneimine (PEI) on silica for CO 2 capture has been conducted. The CO 2 capture performances of resulting sorbents were evaluated on both packed-bed and fluidized-bed reactors. Obtained results indicated that CO 2 adsorptiondesorption performances of sorbents are greatly affected by the operation temperature in both simulated flue gas from coal fired power plant (SCF) and natural gas combined cycle power plant (NGCC). The optimal adsorption temperatures are from 50 to 80 o C for NGCC flue gas and from 70 to 90 o C for SCF flue gas, while the optimal regeneration temperatures are from 110 to 130 o C for both flue gas. Adsorbent containing 30 to 35 wt% PEI fluidized well with both simulated flue gas and steam. Results from this study revealed that PEI impregnated silica is a promising sorbents for CO 2 capture process, using a fluidized-bed reactor, from both coal-fired power and natural gas combined cycle power plants.
