“…Even so, with the simple aforementioned configuration, CO 2 was concentrated from 17 to 43 % (in volume). CO 2 purity could be further increased by modifiying the original cycle, adding a purge step with part of the CO 2 product [8]. However, it must be beared in mind that using part of the product to increase purity has a negative effect over productivity.…”

“…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

“…Zeolite 13X has higher capacity, but activated carbon is less expensive than zeolite and insensitive to moisture. [20][21][22][23][24][25][26] Its surface properties can vary considerably, but its approximate pure-CO 2 sorption capacity can be as high as 10 wt % and its carbon dioxide/nitrogen (CO 2 / N 2 ) selectivity is on the order of 10, at 1 bar and 25°C. [12][13][14][15] Other types of carbonaceous sorbents, such as charcoal and coal, have been studied in a different CO 2 context; [16][17][18][19] however, they have not been explored or proposed for carbon capture from flue gas yet.…”

A low-pressure Carbon Filter Process (patent pending) is proposed to capture carbon dioxide (CO 2 ) from flue gas. This filter is filled with a low-cost carbonaceous sorbent, such as activated carbon or charcoal, which has a high affinity (and, hence, high capacity) to CO 2 but not to nitrogen (N 2 ). This, in turn, leads to a high CO 2 /N 2 selectivity, especially at low pressures. The Carbon Filter Process proposed in this work can recover at least 90% of flue-gas CO 2 of 90%+ purity at a fraction of the cost normally associated with the conventional amine absorption process. The Carbon Filter Process requires neither expensive materials nor flue-gas compression or refrigeration, and it is easy to heat integrate with an existing or grassroots power plant without affecting the cost of the produced electricity too much. An abundant supply of low-cost CO 2 from electricity producers is good news for enhanced oil recovery (EOR) and enhanced coal-bed methane recovery (ECBMR) operators, because it will lead to higher oil and gas recovery rates in an environmentally sensitive manner. A CO 2 -rich mixture that contains some nitrogen is much less expensive to separate from flue-gas than pure CO 2 ; therefore, mixed CO 2 /N 2 -EOR and CO 2 /N 2 -ECBMR methods are proposed to maximize the overall carbon capture and utilization efficiency.

“…Finally, the regeneration method can consist in a combination of heating and evacuation [11][12][13]. The design of an optimised adsorption process is intrinsically related to the adsorbent properties.…”

The effect of oxidation upon the CO 2 capture performance has been studied taking a phenolic resin carbon as the base material. Oxygen surface groups were introduced through liquid and gas phase oxidation treatments, using ammonium persulfate, nitric acid and air, respectively.The surface chemistry of the final carbon is strongly affected by the type of oxidation treatment: liquid phase oxidation introduces a greater amount of oxygen, mostly as carboxylic groups; these are absent in the gas phase oxidised sample that contains mainly ether and carbonyl functionalities. The porous texture of the samples is also affected by the oxidation treatment: through liquid phase oxidation the pore volume is somewhat reduced, while this is slightly developed by air treatment at 693 K. Despite the reduction in the porous volume and the acidic surface, liquid-phase oxidised samples present greater CO 2 adsorption capacity than the starting carbon due to Lewis acid-base interactions with the CO 2 molecule.Moreover: oxidised samples are easily regenerated, and observed heats of adsorption are † Corresponding Author: Tel : +34 985 119090; E-mail address: frubiera@incar.csic.es. (F. Rubiera) 2 typical from physisorption processes, which will facilitate the adsorbent regeneration in cyclic adsorption processes. Oxidation is therefore proposed as a plausible modification technique for developing easy-to-regenerate carbon adsorbents with enhanced CO 2 capture performance.
