Amine-impregnated millimeter-sized spherical silica foams with hierarchical mesoporous–macroporous structure for CO2 capture

Preparation and characterization of multi-walled carbon nanotubes impregnated with polyethyleneimine for carbon dioxide capture

“…The CO 2 adsorption/regeneration capacities of the prepared samples under flue conditions (15% CO 2 /85% N 2 ) were measured by TGA method [35,36]. After degassing and stabilization under N 2 flow, CO 2 was introduced into the sample chamber.…”

Dynamic capture of low-concentration CO2 on amine hybrid silsesquioxane aerogel

“…Moreover, their CO 2 capacities degrade significantly in the presence of water vapor [10,14]. One way to enhance CO 2 adsorption capacity and selectivity is to immobilize amine compounds in highly porous materials to form new amine-based adsorbents [15][16][17][18][19]. Furthermore, water is positive to CO 2 adsorption capacities of amine-based adsorbents [20,21].…”

Efficiency and Energy Analysis of Power Plants with Amine‐Impregnated Solid Sorbents CO2 Capture

“…Whereas a circulating fluidized bed is presumed to be the best option for this first stage, a fixed bed is selected for the sorbent regeneration stage. The residence times of solid particles are higher in fixed beds than in circulating fluidized ones, so a reduction of sorption capacity down to 78 % is considered in the model as a moderate value. Although the use of CFBs leads to the loss of some percentage points in sorption capacity, they are preferred due to its facility for scaling‐up and an improved solid circulation between reactors.…”
