Cost-effective carbon-based amine adsorbents for carbon capture: Equilibrium, kinetics and selectivity

Recent Progress on Porous Carbons for Carbon Capture

“…In the S-doped porous carbon, the KOH activation produced a microporous enriched skeleton with high SBET values of 909−1227 m 2 g −1 . The findings demonstrated that the sulfur heteroatom doping and excellent pore size distribution of the self-doped S-doped carbon led to high CO 2 adsorption of 3.64 and 5.13 mmol g −1 at 25 and 0 °C and 1 bar, as well as IAST selectivity of CO 2 with respect to N 2 (19). This study reveals that because of its high BET surface area, porosity, thermal stability, and low manufacturing cost, S-doped porous carbon made using PPS and KOH is preferable for CO 2 collection.…”

“…Selective adsorption-based separation technology is the most popular carbon recovery technique now in use because it is economical, simple to design, easy to operate, and less expensive . Numerous porous adsorbents are employed in the adsorption separation process, including metal–organic frameworks (MOFs), − covalent-organic frameworks (COFs), − zeolites. − These porous materials have uniform pore distribution and well-defined pore structure, but the capture ability of these materials normally influenced by water molecules which make these porous materials difficult to use directly in practical applications.…”

“…In this regard, adsorbents must have a large surface area, appropriate pore dimensions, and strong adsorption capacity [15]. Traditionally, carbonbased adsorbent materials have been used [16]. These materials usually have low cost and good adsorption performance.…”

Study on the CO2 Capture Separation Process by Temperature Swing Adsorption Based on Nitrogen-Doped Porous Carbon

“…In recent years, the applications of CCUS technology have been restricted because of the high cost of the process of carbon capture, among which the capture efficiency and performance of captured materials are key factors affecting the cost of CO 2 capture. 15,16 Therefore, the development of carbon capture materials with high efficiency and high performance is the biggest challenge faced by CCUS technology. 17,18 A variety of solid adsorbents, including zeolite, 19,20 metal−organic framework (MOF), 21,22 silica material, 23,24 and carbonaceous material 25−27 can be used for CO 2 capture; however, porous carbon with advantages of relatively low renewable energy, high specific surface area, chemical stability, cost effectiveness, and manufacturing maturity has been widely studied.…”

“…The adsorption material is also one of the research focuses of researchers at home and abroad.
