Carbon dioxide adsorption on nitrogen enriched carbon adsorbents: Experimental, kinetics, isothermal and thermodynamic studies

Preparation and CO2 adsorption properties of porous carbon from camphor leaves by hydrothermal carbonization and sequential potassium hydroxide activation

“…The transportation mode of CO 2 molecules on the carbon surface depicts the rst-order nature of the adsorption process and according to rst-order kinetics, the rate of diffusion of CO 2 into the adsorbent surface is faster than the occurrence of chemical reactions on the surface. 5 However, the tting of the experimental equilibrium data to the mathematical models could actually interpretive the results in this study. Therefore, isotherm equilibrium data were analysed by using nonlinear Langmuir and Freundlich models to evaluate the behaviour of CO 2 molecules toward synthesized adsorbents.…”

“…[1][2][3][4] Among these materials, porous carbons have the greatest potential for application because they are derived from a large variety of low-cost resources and have a highly developed porous structure, abundant functional groups, hydrophobicity and high availability. [5][6][7] Porous carbons are oen derived from various biomasses by thermal pyrolysis, chemical activation or hydrothermal carbonization (HTC), followed by carbonization or chemical activation. Zhu et al 8 investigated the characteristics and tetracycline adsorption behaviour of a novel porous carbon prepared using HTC.…”

A review of N-functionalized solid adsorbents for post-combustion CO2 capture

“…In summary, N-doped adsorbents have similar properties to non-N-containing porous solid adsorbents. The only difference was the slightly higher isosteric heats of adsorption of around 30-44 kJ/mol, which demonstrate the good affinity between CO2 and their N-based adsorption sites [189][190][191]. [21,[181][182][183]185].…”

Sound-Assisted Fluidization for Temperature Swing Adsorption and Calcium Looping: A Review

“…As a matter of fact, due to their distinctive properties, size, and nature their surface chemistry and porous structure can be easily adjusted/functionalized at the molecular level, i.e., by introducing chemical groups/ligands with basic functionalities (e.g., carbonates, amino groups, etc.) able to tailor their adsorption behavior towards the CO 2 molecules [ 27 , 28 , 29 , 33 , 34 , 35 , 36 ]. Besides that, it must be considered that most of the sorbents commercially available are produced in a fine powdered form [ 27 , 28 , 29 ].…”
