“…Complete regeneration of the adsorbent bed is achieved in approximately 30 min. It should be mentioned that this CO 2 desorption profile shows a significantly less dispersive character than that of zeolite-type materials [19], due to the easier regeneration of activated carbons.…”

“…Within TSA technologies, the specific case in which the solid is heated by the Joule effect is commonly referred to as electric swing adsorption (ESA) [5,6]. The vast majority of studies dealing with CO 2 post-combustion capture by means of PSA or TSA technologies use zeolites as adsorbent [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. Zeolite 13X is by far the adsorbent most extensively studied in CO 2 separation processes, due to its high selectivity to CO 2 [21].…”

A commercial activated carbon supplied by Norit, R2030CO2, was evaluated as CO 2 adsorbent under conditions relevant to post-combustion CO 2 capture (ambient pressure and diluted CO 2 ). It has been demonstrated that this carbon possesses sufficient CO 2 /N 2 selectivity in order to efficiently separate a binary mixture composed of 17 % CO 2 in N 2 . Moreover, this carbon was easily completely regenerated and it did not show capacity decay after ten consecutive cycles. Three different regeneration strategies were compared in a single-bed adsorption unit: temperature swing adsorption (TSA), vacuum swing adsorption (VSA) and a combination of them, vacuum and temperature swing adsorption (VTSA). Through a simple two step TSA cycle, CO 2 was concentrated from 17 to 43 % (vol). For the single-bed cycle configurations, the productivity and CO 2 recovery followed the sequence: TSA

“…They suggested that the combination of thermal and vacuum could improve desorption rate. Tlili et al (2009) also studied the use of VTSA and could achieve 99% purity for both VSA and TSA processes. They concluded that the recovery depended on desorption temperature and purge flow rate.…”

Global warming resulting from the emission of greenhouse gases, especially CO 2 , has become a widespread concern in the recent years. Though various CO 2 capture technologies have been proposed, chemical absorption and adsorption are currently believed to be the most suitable ones for post-combustion power plants. The operation of the chemical absorption process is reviewed in this work, together with the use of absorbents, such as the ionic liquid, alkanolamines and their blended aqueous solutions. The major concerns for this technology, including CO 2 capture efficiency, absorption rate, energy required in regeneration, and volume of absorber, are addressed. For adsorption, in addition to physical adsorbents, various mesoporous solid adsorbents impregnated with polyamines and grafted with aminosilanes are reviewed in this work. The major concerns for selection of adsorbent, including cost, adsorption rate, CO 2 adsorption capacity, and thermal stability, are compared and discussed. More effective and less energy-consuming regeneration techniques for CO 2 -loaded adsorbents are also proposed. Future works for both absorption and adsorption are suggested.

“…The adsorption process is typically cycled between two beds of adsorbents; one bed is adsorbing CO 2 while the other is being regenerated. In the regeneration process, CO 2 can be desorbed by either pressure swing adsorption (PSA) (pressure reduction) (Ishibashi et al, 1999;Gomes and Yee, 2002;Yokoyama, 2003), temperature swing adsorption (TSA) (temperature increase) (Drage et al, 2009;Tlili et al, 2009), electrical swing adsorption (ESA) (Grande and Rodrigues, 2008;Grande et al, 2009), which adjusts the electric current passed through the adsorbents, or vacuum swing adsorption (VSA) (Chaffee et al, 2007).…”
