“…Thus, it is crucial to know the composition and structure of each particular biomass waste feedstock to identify the most suitable procedure for the adsorbent development. 161,[287][288][289][290][291] Understanding the properties of carbon-based adsorbents is imperative to carry out application-specific optimisation and maintain long-term carbon stability. In this sense, the adsorbent's performance and efficiency for capturing CO 2 from gas streams rely on the surface chemistry and porosity development, which are heavily dependent on three main aspects: feedstock composition, preparation method and subsequent physical or chemical modifications.…”

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.

“…Typically, the physicochemical characteristics of feedstock strongly influence the structural and textural features of BPCs. Zhu et al 226 collected data from several reports and devised a correlation of CO 2 uptake capacity with fixed carbon content, carbon content, moisture content, ash content, and volatile content. The authors demonstrated a significant correlation between CO 2 uptake with C content and fixed carbon content, illustrating an increasing trend.…”

“…To address this issue, there are ongoing efforts to develop new technologies and approaches to capture and store carbon dioxide from the atmosphere, which could help to slow or even reverse the rise in CO 2 concentration over time. , For instance, precombustion, postcombustion, and oxy-fuel are three different technologies used in carbon capture and storage (CCS) to decrease carbon dioxide emissions from industrial processes and power plants. − All of these technologies are expensive and energy-consuming. Therefore, researchers have tried to find new technologies to reduce carbon dioxide capture costs .…”

Chemical looping combustion (CLC) is an innovative cyclic process for fuel combustion to intrinsically separate carbon dioxide. In this process, oxygen and fuel are contacted by an intermediate oxygen carrier (OC), a metal oxide/metal that can alternately be reduced and oxidized. In this study, a yolk (Al2O3)–shell (ZrO2) was synthesized as the support of the OC and 20 wt % copper oxide was impregnated on the surface of it. The structure and cyclic reduction–oxidation (redox) performance of the CuO-impregnated yolk–shell sample were compared with those of CuO-impregnated core (Al2O3)–shell (ZrO2) and CuO-impregnated alumina oxygen carriers in the CLC process. The synthesized OCs were characterized by Brunauer–Emmett–Teller (BET) surface area, X-ray powder diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and energy-dispersive X-ray spectroscopy (EDX) dot mapping. A homogeneous coating of the zirconia on the alumina was obtained for the yolk–shell material. The pore size distribution became narrow in the presence of the zirconia coating. Furthermore, a yolk–shell architecture prevented the contact between the yolk (Al2O3) and the copper oxide materials, and CuAl2O4 spinel formation was inhibited. The obtained results showed that the oxygen transport capacities of the 20CuO/Al–C@Zr (yolk–shell support), 20CuO/Al@Zr (core–shell support), and 20CuO/Al oxygen carriers are 3.80, 3.47, and 3.4 wt %, respectively. The oxygen carrier with the yolk–shell support exhibited the highest activity, oxygen transport capacity, and coke formation resistance.
