“…A total of 141 activated carbons prepared in-house have been evaluated for the different CO 2 capture applications (post-combustion, 86,[122][123][124][125]140,207,216,231,233,239,263,297,301,312,313,[318][319][320][321][322] industrial flue gas streams, 45,235,301,308,313,315 and biogas purification 219,274,304,307,316,[323][324][325][326] ). In this regard, the VSA cycles on a spent coffee grounds-based AC (Group's patent ES2526259) showed that a feed with 14 vol.% CO 2 could be concentrated up to 75% (recovering 84% of the CO 2 in the feed) in a VTSA configuration consisting of pressurisation with feed, adsorption at 50°C and 130 kPa, rinse with CO 2 , co-current depressurisation down to 20 kPa, and a production stage consisting of evacuation down to 10 kPa with simultaneous heating up to 70°C and a light purge step at 10 kPa.…”

Adsorption using bio-based adsorbents has been pointed out as an economical and environmentally benign technology for CO 2 gas separation and storage. A bio-based adsorbent can be fabricated from low-cost worldwide available biomass feedstock and bio-wastes from different industries (e.g., dairy manure, forestry, agriculture). As a result, it is a carbon rich material of hydrophobic nature, activated to gain high porosity development, and requires mild regeneration conditions. However, large-scale deployment of bio-based adsorption processes remains challenging. Our group has been intensively developing biomass-based adsorbents in conjunction with the design of tailored CO 2 adsorption-based cyclic processes for the envisioned application. Herein, key concepts on adsorption technology, biomass waste management, and different activation techniques for biomass-based adsorbent precursors are discussed. This review addresses the most relevant studies in the literature, from lab experimentation on a milligram scale (volumetric and gravimetric tests) to dynamic tests in bench or large-scale cyclic adsorption processes (i.e., pressure swing adsorption, temperature swing adsorption, vacuum swing adsorption). Therefore, the main target is to give a holistic view of the industrial applications where CO 2 separations with these materials are more suitable. Finally, concluding remarks and future perspectives of bio-based adsorbents in carbon capture are presented.
