Abstract: Since the time of the industrial revolution, the atmospheric CO(2) concentration has risen by nearly 35 % to its current level of 383 ppm. The increased carbon dioxide concentration in the atmosphere has been suggested to be a leading contributor to global climate change. To slow the increase, reductions in anthropogenic CO(2) emissions are necessary. Large emission point sources, such as fossil-fuel-based power generation facilities, are the first targets for these reductions. A benchmark, mature technology for the separation of dilute CO(2) from gas streams is via absorption with aqueous amines. However, the use of solid adsorbents is now being widely considered as an alternative, potentially less-energy-intensive separation technology. This Review describes the CO(2) adsorption behavior of several different classes of solid carbon dioxide adsorbents, including zeolites, activated carbons, calcium oxides, hydrotalcites, organic-inorganic hybrids, and metal-organic frameworks. These adsorbents are evaluated in terms of their equilibrium CO(2) capacities as well as other important parameters such as adsorption-desorption kinetics, operating windows, stability, and regenerability. The scope of currently available CO(2) adsorbents and their critical properties that will ultimately affect their incorporation into large-scale separation processes is presented.

Populus wood biomass-derived graphene for high CO2 capture at atmospheric pressure and estimated cost of production
TL;DR: In this paper, the effect of different parameters, such as various KOH/C weight ratios (2:1−4:1g/g), different heating temperatures (750−950°C) and heating time (30−90min), on the surface characteristics and CO2 uptake capacity of the as-synthesized graphene was investigated.

CO2 adsorption on fine activated carbon in a sound assisted fluidized bed: Effect of sound intensity and frequency, CO2 partial pressure and fluidization velocity
TL;DR: In this paper, a sound-assisted fluidized bed of fine activated carbon is used to improve the gas-solid contact by promoting a smooth fluidization regime, and the results show the capability of the sound in enhancing the adsorption process and confirm that sound assisted fluidization of fine solid sorbents is a valid alternative to the fixed bed technology, which require also an additional previous step of pelletization.

TL;DR: In this paper, a double salt Na2Ca(CO3)2 was generated from the reaction of CO2 with CaO and Na2CO3, which showed high CO2 affinity above 600°C and its sorption/regeneration kinetics were faster than those of the conventional CaO-based sorbent.
