“…The most common known adsorbents are activated carbons and zeolites being exploited for CO 2 separation and storage. Zeolites could adsorb a higher quantity of CO 2 than does by activated carbon at low operating pressures (< 20 kPa) [4,5], whereas carbon-based adsorbents are better for CO 2 storage applications [5,6]. Conversely, the obvious merits of carbon adsorbents over zeolites are cost penalties, hydrostability, lower regeneration energy, and easiness of production on a commercial scale [7].…”

Carbon capture using adsorption processes can significantly mitigate global warming. Mg-MOF-74 is a distinct reticular material amongst other adsorbents owing to its distinguished carbon dioxide adsorption capacity and selectivity under lowpressure applications, while MIL-100(Fe) has lower CO 2 adsorption capacity, but extraordinary thermal and hydrostability in comparison to many classes of MOFs. In this paper, we present CO 2 adsorption characteristics of new compounds formed by the incorporation of multi-walled carbon nanotubes (MWCNTs) into Mg-MOF-74 and MIL-100(Fe). This was done to improve the thermal diffusion properties of the base MOFs to enhance their adsorption capacities. The new composites have been characterized for degree of crystallinity, and the CO 2 and N 2 equilibrium uptake. The real adsorption separation has been investigated by dynamic breakthrough tests at 297 K and 101.325. The equilibrium isotherm results showed that Mg-MOF-74 and 0.25 wt% MWCNT/MIL-100(Fe) (MMC2) have the highest CO 2 uptake in comparison to the other investigated composites. However, the interesting results obtained from breakthrough tests demonstrate that good improvements in the CO 2 adsorption uptake and breakthrough breakpoint over pristine Mg-MOF-74 have been accomplished by adding 1.5 wt% MWCNT to Mg-MOF-74. The improvements of CO 2 adsorption capacity and breakpoint were about 7.35 and 8.03%, respectively. Similarly, the CO 2 adsorption uptake and breakthrough breakpoint over pristine MIL-100(Fe) are obtained by 0.1 wt% MWCNT/MIL-100(Fe) (MMC1) with improvements of 12.02 and 9.21%, respectively.

“…[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. For example, in the context of displacing coal-bed methane with CO 2 , it has been shown that virgin coal has a higher capacity for CO 2 than it does for methane, 19 again, only at elevated pressures.…”

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.

“…Aluminophosphates (ALPO) have been shown to be interesting materials to separate CO 2 from CO 2 -N 2 mixtures as obtained from flue gas [4]. CO 2 separated from the mixture can afterwards be sequestered in geological deposits [5].…”
