“…In contrast to the currently preferred absorption technologies (mainly amine scrubbing based systems) which still present important drawbacks related to sorbent regeneration and corrosion issues (GCCSI, 2012;Yan et al, 2012), adsorption has shown a great potential to significantly cut down the overall costs by providing substantial energy savings and reduction of the equipment sizes (Ho et al, 2008;Radosz et al, 2008;Davidson, 2009). Main challenges of post-combustion applications arise from dealing with large flue gas volumes, low CO2 partial pressure, and common presence of water vapor in the outlet stream (Sreenivasulu et al, 2015). Therefore, appropriate adsorbents must present sufficient adsorption capacity, high CO2 selectivity, adequate density and hardness, low abrasion index, and good stability in moisture conditions.…”

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.

“…However, there are other technologies that have also shown potential to be energy and cost competitive such as: adsorption, membranes and lowtemperature separation (also referred to as "cryogenics" in the literature) (Aaron and Tsouris, 2005;Sreenivasulu et al, 2015). Each of those technologies has their respective advantages and disadvantages (Huisingh et al, 2015).…”

“…Carbon capture is done with various technical options of absorption, adsorption, cryogenic separation and membrane separation [1], [2]. CO 2 capture (CC) and separation from industrial process during coal gasification has got industrial importance due to its high temperature (>400 o C) capture from H 2 +CO 2 gas mixture as shown in Fig.…”

Abstract-CO 2 influe gas from anthropogenic emission is one of the major contributors for global warming among greenhouse gases (GHG). Alkaline metal oxide (CaO, MgO, etc) adsorbents got industrial importance due to its use at high temperature CO 2 capture in coal gasification to separate hydrogen gas. In this paper, we discussed on the synthesis methods of mechanical mixing, freeze granulation and dispersion methods of adsorbents for CO 2 capture. Operational issues of packed bed reactor used for CC using the alkaline earth metals doped flyash. Pore size and surface areas dependence of monolithic pellets on carbonation -calcination temperatures. CC variation with monolithic pellet size and carbonation temperatures. Breakthrough curves of adsorption for the adsorbents were discussed. Adsorbents of limestone doped with flyash were analyzed using various analytical tools and the findings were reported.Index Terms-Alkaline metal oxides doped with flyash, carbon capture, operational experiences in packed bed reactor, synthesis protocol of monolithic adsorbents.
