“…The above discussed diffusion and mass transfer limitations make this percentage to fall down to approximately 25% for the activated carbon GCL, what would imply the necessity of increasing the bed length (or the bed weight) to achieve a better use of the adsorbent. The comparison of these values to others reported in the literature shows that the capacity value obtained in column experiments for the activated carbon fiber, FCL, is considerably higher than those reported by Jadhav et al (2007) with modified zeolites 13X; and Sjostrom and Krutka (2010) with different carbon materials at very similar experimental conditions. Regeneration capacity, defined as the capacity of a specific material to be used in subsequent adsorption-desorption cycles, is another key issue that can be addressed by dynamic fix bed studies.…”

A series of porous carbon materials obtained from biomass waste have been synthesized, with different morphologies and structural properties, and evaluated as potential adsorbents for CO2 capture in post-combustion conditions. These carbon materials present CO2 adsorption capacities, at 25°C and 101.3 kPa, comparable to those obtained by other complex carbon or inorganic materials. Furthermore, CO2 uptakes under these conditions can be well correlated with the narrow micropore volume, derived from the CO2 adsorption data at 0°C ( ) V CO 2 DR . In contrast, CO2 adsorption capacities at 25°C and 15 kPa are more related to only pores of sizes lower than 0.7 nm. The capacity values obtained in column adsorption experiments were really promising. An activated carbon fiber obtained from Alcell lignin, FCL, presented a capacity value of 1.3 mmol/g (5.7%wt). Moreover, the adsorption capacity of this carbon fiber was totally recovered in a very fast desorption cycle at the same operation temperature and total pressure and, therefore, without any additional energy requirement. Thus, these results suggest that the biomass waste used in this work could be successfully valorized as efficient CO2 adsorbent, under post-combustion conditions, showing excellent regeneration performance.

“…silica's, polymers, zeolites) with amine functional groups immobilized on or grafted to its surface (Ebner et al, 2011). The key strengths of this type of sorbents material include high CO 2 capacities (Veneman et al, 2012), fast CO 2 uptake rates, a low heat of adsorption (63.2 kJ mol −1 (Gray et al, 2009)) and relatively mild regeneration conditions (373-423 K) compared to other chemical sorbents (Sjostrom and Krutka, 2010).…”

“…A wide variety of solid sorbents is currently under study to separate CO 2 from energy-generating coal-fired power plants such as zeolites, activated carbons, calcium oxides, hydrotalcites, supported amines and metal-organic framework (MOF) materials [3,[5][6][7][8][9][10]. Physisorbents such as activated carbons (AC) and aluminosilicate zeolite molecular sieves show considerable promise for CO 2 adsorption because of their good adsorption capacities, rapid adsorption kinetics and low regeneration energies.…”

“…However, at higher pressures, the CO 2 uptake of AC can surpass that of zeolites [3,11]. Additionally, AC have a hydrophobic character [6] and can be produced from a wide variety of sources (coal, industrial byproducts, biomass sources, etc. ), which makes them cheaper to produce on an industrial scale than other sorbents.…”

a b s t r a c tIn this study a commercial activated carbon (Norit R2030CO2) was assessed as a solid sorbent for precombustion CO 2 capture. This technology involves the removal of CO 2 from the shifted-syngas prior to the generation of electricity and the production of high-purity clean H 2 . The CO 2 equilibrium adsorption capacity and breakthrough time were evaluated in a flow-through system where the adsorbent was subjected to four consecutive adsorption-desorption cycles. A CO 2 /H 2 /N 2 gas mixture (20/70/10 vol.% at normal conditions) was employed as the influent gas stream. Response surface methodology (RSM) was used to assess the combined effect of the adsorption CO 2 partial pressure and temperature (independent variables) on CO 2 capture capacity and breakthrough time (response variables) for the activated carbon. The CO 2 partial pressure ranged from 1 to 3 bar within a total pressure range of 5-15 bar and a temperature range of 25-65 • C. No interaction effect between the two independent variables on the responses was found. The CO 2 partial pressure was observed to be the most influential variable, with high values leading to an increase in both the CO 2 capture capacity and the breakthrough time. However, an increase in the temperature led to a decrease in both response variables. The maximum values of the response variables within the experimental region studied were obtained at 25 • C and under a CO 2 partial pressure of 3 bar (15 bar total pressure).
