“…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.…”

“…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].…”

“…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.…”

Some of the relevant post‐combustion CCS research trends includes the reduction of the energy consumption required for regeneration. It is a priority to find novel solvents that show high affinity for CO2 together with an ease of regeneration and reuse. Recently, impregnated solid sorbents have been suggested to tackle with these issues. In particular amine‐impregnated solid sorbents require less regeneration energy due to the reduction in water content and the higher heat capacity of solids. As a consequence, they may have the ability to reduce the efficiency penalty of CCS in power plants. Several studies have quantified the efficiency penalty of CO2 capture in commercial power plants with amine absorption. It is generally assumed a reduction of 7–10 efficiency points. Nevertheless, there is not a clear quantification of the effect of solid sorbent capture plants on efficiency penalty. This paper tries to shed some light on this issue. The objective of this work is to demonstrate and quantify the effect on net power and efficiency penalty of using amine‐impregnated solid sorbents when applied as an option to carbon capture. A full process integration of the system and an overall optimisation for power generation have been carried out. Interesting results have been achieved; it is possible to reduce the efficiency penalty down to 6.7 efficiency points. This figure could make feasible the impregnated amine solid sorbent as a future and promising option for CO2 capture.
