“…Adsorption of carbon dioxide on solids has the advantage that high capacities can be obtained by suitable choice of solids the optimum, high selectivity, high capacity solid sorbent. A variety of materials have been investigated, including activated carbon (Pellerano et al, 2009) and mesoporous silica (Huang et al, 2002;Ma et al, 2009). These materials generally have poor capacities and selectivities, so that their modification by amines has been considered (Hicks et al, 2008;Kim et al, 2008;Knowles et al, 2005aKnowles et al, , 2006Liang et al, 2008;Plaza et al, 2007;Zelenak et al, 2008).…”

“…Adsorption via porous materials to remove CO 2 has been developed recently for its economic and environmental advantages 3. Accordingly, carbonaceous materials,4–6 zeolites,7 metal‐organic frameworks (MOFs),8 covalent‐organic frameworks (COFs),9 and zeolitic imidazolate frameworks (ZIFs)10 are being considered as candidates to capture CO 2 .…”

CO 2 /CH 4 in our samples ACB-2 and 5 have been measured at 298 and 348 K and different compositions, corresponding to the pre-and postcombustion conditions for CO 2 capture. The Dual-Site Langmuir-Freundlich (DSLF) model-based ideal-adsorbed solution theory (IAST) was also used to solve the selectivity of CO 2 over N 2 and CH 4 . The selectivities of ACBs for CO 2 /CH 4 are in the range of 2-2.5, while they remain in the range of 6.0-8.0 for CO 2 /N 2 at T ¼ 298 K. In summary, this work presents a new type of adsorbent-ACBs, which are not only good candidates for CO 2 and CH 4 storage but also for the capture of carbon dioxide in pre-and postcombustion processes. *S BET is the BET surface area and S Langmuir is the Langmuir surface area. V t , V DA , and V meso are the total pore volume, micro-pore volume, and meso-pore volume, respectively.

This work considers the possibility to transport CO2 in an adsorbed phase and analyzes its cost as a function of transported quantities, transport conditions and transportation means. CO2 adsorption capacities of 6 different adsorbents, comprising 4 activated carbons and 2 zeolites, were empirically evaluated in a given range of pressure and temperature. The adsorbent with the highest mass adsorption capacity (AC1), as well as another sorbent described in the literature (AC5) were selected to be used for CO2 transportation by ships, trains or trucks. Their characteristics and performances were then used to develop an economic analysis of transportation costs and CO2 emissions generated by the transport with or without storage. Economic evaluation of CO2 batch transport shows that CO2 transported in an adsorbed phase by train was seen to be almost competitive on distances between 250 and 500 km, in comparison to liquefied CO2. One of the activated carbon appeared to be competitive on short distances by truck when transport was not followed by storage. Ship transport of adsorbed CO2 on distances around 1500 km was competitive, when CO2 was used as delivered; there was an over cost of only 16%, when there was storage after the transport. The CO2 emissions generated by CO2 transport and storage when transport is carried out in an adsorbed phase were smaller than the ones generated by liquid phase transport below 1200 km, 500 km and 300 km by ship, train and truck respectively, as a function of the adsorbent used. Adsorbed CO2 transported on 1500 km by ship generated 27% less CO2 emissions than liquid phase and 17% by train for a distance of 250 km and 16% by truck on 150 km, although these differences were decreasing with the distance of transport
