“…For regeneration, the sorbent is moved to desorber, where it is heated to release the captured CO 2 . The CO 2 can also be removed from flue gases via chemical solvent scrubbing method (Guo et al 2013;Jin and Zhang 2011;Webley 2014;European Technology Platform 2014). Figure 2 briefly explains the CO 2 capture technologies and processes.…”

In the last few decades of industrialization, the concentration of CO 2 in the atmosphere had increased rapidly. Different organizations have invested considerable funds in research activities worldwide for CO 2 capture and storage. To date, significant work has been done and various technologies have been proposed for CO 2 capture and storage. Both adsorption and absorption are promising techniques for CO 2 capture, but low-temperature adsorption processes using solid adsorbents are the prevailing technique nowadays. In this review paper, a variety of adsorbents such as carbonaceous materials, dry alkali metal-based sorbents, zeolites, metal-organic frameworks (MOFs) and microporous organic polymers (MOPs) have been studied. Various methods of chemical or physical modification and the effects of supporting materials have been discussed to enhance CO 2 capture capacity of these adsorbents. Low-temperature (\100°C) adsorption processes for CO 2 capture are critically analyzed and concluded on the basis of information available so far in the literature. All the information in CO 2 adsorption using different routes has been discussed, summarized and thoroughly presented in this review article. The most important comparative study of relatively new material MOFs and MOPs is carried out between the groups and with other sorbent as well.

“…The CO 2 desorption capacities are very close to adsorption capacities, the tiny difference results from the CO 2 desorption during purge process. It reveals that the adsorbed CO 2 in AH-RFSA could be desorbed at a only 80°C within less than 5.5 or 7.0 min without or with water, while adsorbed CO 2 with other amine based adsorbents is generally desorbed around 100-140°C with a longer time [18,35,36,[78][79][80][81][89][90][91], indicating that AH-RFSA is more dynamic and energy-saving.…”

“…Partial gasification using water vapor, carbon dioxide, or their mixtures increases the surface area in activated carbons [5,6]. However, chemical activation with acids or alkalis, among other chemical compounds, have been also reported to improve the surface area in ACs [7][8][9][10][11][12][13][14]. Wei et al [15] observed higher specific surface area (SSA) values with large mesoporous volume when KOH was used.…”

Activated carbon (AC) was gained from Pinus montezumae (PM) wood sawdust and chemical activation with K2CO3 was used for obtaining activated carbons. Variations in reaction conditions such as temperature, impregnation ratio (IR), and activation time were carried out to study their influence on the specific surface area (SSA) and average pore volume (APV) in AC. Materials were analyzed by means of Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and X‐ray diffraction (XRD) to determine the functional groups, pore structure, and morphology of pine sawdust and activated carbons. Activated carbons were amorphous in nature with some crystalline regions.
