Biomass/Biochar carbon materials for CO2 capture and sequestration by cyclic adsorption processes: A review and prospects for future directions

Introducing a Linear Empirical Correlation for Predicting the Mass Heat Capacity of Biomaterials

“…Furthermore, cement, steel, and iron manufacturers are the subsequent sources of CO 2 emissions [ 4 ]. In this way, significant attention has been paid to carbon capture [ 8 ] and sequestration strategies [ 9 ] to reduce, control, and utilize greenhouse gases, including CO 2 , methane, nitrogen, sulfur, chlorofluorocarbons, and so on [ 10 , 11 ]. To this end, according to the BLUE map scenario of the international energy agency [ 12 ], sustainable energy sources, including biomass [ 13 ], biogas [ 14 ], and solar energy [ 15 ], have been introduced as promising candidates to replace traditional fossil fuels.…”

Enhanced Carbon Capture Behavior of Carbon Fibers via Ionic Liquid Modification

“…In the academic and industrial fields, extensive attention has been attracted to the development of diverse solid sorbents towards efficient CO 2 capture, [4] including but not limited to porous organic polymers (POPs), [5] metal‐organic frameworks (MOFs), [6] carbon‐related materials, [7] modified silica, [8] zeolites, [9] and metal oxides [10] . Among those categories, carbon materials, such as activated carbon, mesoporous carbon, carbon nanofiber, and carbon nanotubes, which could be derived from different carbon precursors (e. g., biomass, biochar, polymer, ionic liquids, and MOFs) and synthesized via various thermal treatment procedures, have been widely deployed in post‐combustion CO 2 capture [11–17] . In order to improve the CO 2 capture capacity of the carbon materials, extensive studies have been conducted via strategies such as heteroatoms‐doping (e. g., O, N, F, or S), [18] inorganic base activation (e. g., NaOH, KOH, NaNH 2 ), [19] utilization of templates during the preparation process, [20–21] and anchoring CO 2 ‐philic functionalities on the surface, [17] aiming at increasing the surface areas, tuning the porosity distributions, and enhancing the interaction strength with CO 2 .…”

For example, the carbon spheres being obtained by the KOH activation pathway exhibited abundant small micropores (< 0.8 nm), high surface area (2400 m 2 g À 1 ), and promising CO 2 uptake capacity up to 8.9 mmol g À 1 at 273 K and CO 2 pressure of 1 bar.…”

Employing computational fluid dynamics technique for analyzing the PACK-1300XY with methanol and isopropanol mixture

“…Separation technologies, like ionic liquid-based 1 , 2 and microvaiwe assisted 3 absorption, adsorption 4 – 7 , membrane 8 , circulating purification 9 , and fluidizedization 10 – 12 have a wide ranges of application in different applications. The distillation column is likely the most well-known process to separate either feedstock and product stream by considering the relative volatility 13 – 15 .…”
