“…This is in agreement with previously reported adsorption mechanisms over other carbon materials with basic functionalities and is mainly attributed to different polarities of adsorbate and adsorbent surfaces. Thus, in this case, further or complete regeneration would require longer desorption times or alternative regeneration strategies, for instance, temperature swing adsorption (Hedin et al, 2013). These results are really interesting if they are compared to other inorganic materials.…”

Biomass Waste Carbon Materials as adsorbents for CO2 Capture under Post-Combustion Conditions

et al. 2016

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.

“…The design of an optimised adsorption process is intrinsically related to the adsorbent properties. Therefore an important research effort has also been directed towards materials development [14][15][16][17]. The ideal adsorbent for PCC should present high stability, sufficient adsorption capacity at low CO 2 partial pressures, high selectivity, easy regeneration, and low cost.…”

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.

Oxidation is therefore proposed as a plausible modification technique for developing easy-to-regenerate carbon adsorbents with enhanced CO 2 capture performance.
