“…They present a series of advantages such as competitive sorption capacity at low CO 2 partial pressure, faster kinetics, high CO 2 /N 2 selectivity , and excellent tolerance to moisture. High cost, susceptibility to flue gas impurities, amine degradation at higher temperatures (>100 C), and need for time consuming, energy intensive TSA are major disadvantages (Drage et al, 2009a;Xu et al, 2005;Krutka and Sjostrom, 2010;Nasr et al, 2013;Spigarelli and Kawatra, 2013). Amine-grafted materials show faster kinetics, low diffusion resistance, higher cyclic stability, and better thermal stability compared with amine-impregnated solids.…”

“…Temperature or temperature‐pressure swing processes are the most common techniques applied in the regeneration of the sorbent. Main advantages of the AISS in comparison to aqueous MEA lay on the reduction of energy demand for regeneration due to less evaporation of water, and lower specific heat capacity of the sorbent, which allow to obtain a reduction of overall CO 2 capture costs . The heat required for the CO 2 desorption step in processes making use of AISS is around 1.5 GJ/tCO 2 ,.…”

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.

“…Therefore, solid adsorbents have been considered for this purpose, despite most of the current capture infrastructure is based on liquid state amine based absorbents. Regardless of either adsorbents or absorbents, capture materials must include the characteristics of null (or minimum) toxicity, low corrosivity, low regeneration cost and low degradation properties . There is an increasing interest on some new alternative materials that are considered as alternative CO 2 capture solvents such as ionic liquids and deep eutectic solvents …”

Investigation of the binding affinity gases on porous adsorbents are important for establishing understanding of effective carbon dioxide adsorption and design target specific sorbents for capturing hazardous gases for environmental protection and fuel upgrading. A Density Functional Theory (DFT) study that highlights the impact of covalent organic polymer (COP) design has been conducted to explain the molecular and electronic structure, investigate the interaction sites and elucidate the experimental findings on carbon dioxide (CO2) and nitrogen (N2) sorption on these porous structures. DFT calculations were used to infer the details of the type and the strength of the polymer – gas interaction modes at various interaction sites as well as to quantify short‐range interactions between the polymer – gas via topological characteristics analysis of intermolecular forces. Results obtained in this study were used to shed light on CO2 and N2 affinity of the studied polymer structures; interpretations regarding to the macroscopic behaviors were discussed and conclusions were attained on the characteristics of the adsorption type and mechanism.
