Breakthrough adsorption studies of mixed gases on mango (Mangifera indicaL.) seed shell derived activated carbon extrudes

Efficient CO2 Capture by Ultra‐high Microporous Activated Carbon Made from Natural Coal

“…4b. Similar observations were reported earlier during CO 2 uptake by various activated carbon adsorbents [60,61]. Nevertheless, it can also be noticed that the experimental data fitted well with the Dubinin-Radushkevich model (R 2~0 .99) as indicated in Tab.…”

Gas storage

“…The activated carbons produced from grass cutting and horse manure showed higher CO2 adsorption capacities due to a larger volume of ultramicropores (Hao et al, 2013). Munusamy et al showed that using carboxyl methyl cellulose sodium salt and soluble starch as binders to convert a powdered mango seed shell derived activated carbon into extruded form they could enhance the maximum CO2 equilibrium adsorption capacity from 14.3 wt.% to 21.3 wt.% at 0.1 MPa and 273 K explained by the formation of surface functionality by the binders on the extruded AC (Munusamy et al, 2015).…”

“…The development of porous adsorbent materials compatible with the adsorption of gases such as CH4, CO2 and H2has become then a target issue for researchers, with the goals of finding cheap and ecofriendly precursor materials and implementing the synthesis procedures that will produce better yielding and the required properties of the material. There are a variety of porous materials used for the adsorption of gases such as zeolites (Cavenati et al, 2004;Chen and Ahn, 2014;Kacem et al, 2015), carbon nanotubes (Gui et al, 2013;Lee et al, 2006), metal organic frameworks (MOFs) (Casco et al, 2015a;Llewellyn et al, 2008;Zhou et al, 2007) and activated carbons (Buss, 1995;Byamba-Ochir et al, 2017;Munusamy et al, 2015). Among these materials, activated carbons are the most widely used in the industry, due to their ease of synthesis as well as the possibility of their pore tailoring and chemical functionalization.…”

Tailoring Low-Cost Granular Activated Carbons Intended for CO2 Adsorption

“…Therefore, before being used in fixed bed adsorption columns, the material should be extruded or conformed into monoliths. Besides implying additional costs, these procedures usually require the employment of a binder, which obstructs part of the porosity (Jordá-Beneyto et al, 2008 ; Munusamy et al, 2015 ).…”

“…As activating methodologies, we investigated in depth the chemical activation with dehydrating agents (H 3 PO 4 or ZnCl 2 ) and the physical activation with CO 2 . Although there are some scarce works reporting the use of these approaches in the production of ACs intended for CO 2 adsorption (Presser et al, 2011 ; Vargas et al, 2011 ; Bae and Su, 2013 ; Ello et al, 2013 ; Balsamo et al, 2014 ; Ludwinowicz and Jaroniec, 2015 ; Munusamy et al, 2015 ; Ahmed et al, 2019 ) and the reported gravimetric CO 2 uptakes are, in a general way, lower than those verified for KOH activated carbons (compare the data in Supplementary Table 1 ), none of the existing works concerned a systematic study in which the activation conditions are screened in order to achieve materials with improved performances. Further, the results were always considered only on a mass basis instead of a volume basis.…”
