“…However, the difference in the diffusion rate of gas molecules causes the CH4 molecule to pass through the pores faster than the CO2 molecule which allows the two gases to separate. The diffusivity of CH4 and CO2 was 1 x 10 -10 m 2 /s and 1 x 10 -11 m 2 /s respectively (Prasetyo et al, 2020). In addition, carbon is more selective towards CO2 than CH4 because of its higher affinity for carbon.…”

“…One of the effective potential molecular sieves for CO2 gas separation is the carbon molecular sieve (CMS). CMS is a porous carbon material with most of the pores scattered in micropore size, which are able to distinguish molecules based on differences in diffusion rate, size, and shape (Mohamed et al, 2010;Prasetyo et al, 2020;Silvestre-Albero et al, 2009;Wahby et al, 2012). The separation of gas mixtures at CMS is determined by several parameters such as pore structure, affinity, and interaction of gas molecules with the carbon surface (Prasetyo et al, 2017).…”

Methane (CH4) and carbon dioxide (CO2) are the main components of a renewable energy source of biogas. Separation of CO2 from biogas is significantly important to improve biogas performance, due to heating value in biogas depends on the concentration of methane. One of the gas separation technologies that has been widely used in chemical industries is carbon molecular sieve (CMS). This research explores the potential of CMS for biogas purification. CMS was prepared by modification of palm kernel shell-derived porous carbon using amine groups such as monoethanolamine (MEA), 2-amino-2-methyl-1-propanol (AMP), and diethanolamine (DEA). The effect of amine types on the separation parameters was studied by using a breakthrough experiment to obtain the most potential CMS materials. The methods of this research include the process of carbon oxidation using hydrogen peroxide, impregnation with an amine group, characterization of the CMS material obtained, CO2 and CH4 gas separation testing with a breakthrough system. The CMS was characterized by using N2 sorption analysis, fourier transform infrared spectroscopy, and scanning electron microscopy. The breakthrough experiment showed that CMS-MEA had the highest performance for separating CO2 and CH4 gases. In addition, the results also showed that loading of amine groups on carbon caused an increase in the uptake capacity of CO2, and the highest capacity was achieved by CMS-MEA of 13.2 mg/g.

“… 6 Adsorption-based separation occurs due to the difference in affinity and diffusivity of CO 2 and CH 4 . 7 Several types of molecular sieves, including zeolite molecular sieve (ZMS), 8,9 carbon molecular sieve (CMS), 10–13 and metal–organic framework (MOF), 14,15 are widely used for adsorption-based separation. Molecular sieves made from carbon are relatively stable long-term due to the low heat of adsorption and can be synthesized from a variety of materials, including coal, 16,17 biomass, 10,18 and polymer.…”

Rapid industrialization and urban development around the world have significantly increased carbon dioxide emissions, adversely affecting climate and ecosystems. Therefore, carbon capture and storage emerged as a promising route to reduce environmental CO2 concentration. Among various CO2 capture technologies, adsorption through carbon‐based porous materials has attracted particularly strong attention. This is primarily due to their high specific surface area, selective CO2 adsorption, moderate heat of adsorption, tunable morphology, and reduced degradation in moisture. This review critically examines carbon‐based CO2 sorbents derived from diverse sources. The key factors controlling adsorption performance, including the impact of structural and functional properties are discussed. The future research directions in this rapidly emerging field, contributing to the decarbonization of the global economy and society, are highlighted.
