Activated carbon from biomass: Preparation, factors improving basicity and surface properties for enhanced CO2 capture capacity – A review

Adsorption of CO2 Using “Sugar Cube”-Shaped Zeolite A Type Derived from Thermally Treated Kaolin and NaOH

“…17 In addition, ZIF has significant disadvantages as opposed to advantages, such as expensive material preparation, poor thermal and chemical stability, and other issues. The other absorbents like activated carbon (AC) 18 have better surface area compared to the other adsorbents, and they have their own limitations such as less thermal stability at higher temperatures, which leads to certain limitations in CO 2 adsorption. Amine supported mesoporous silica 19 has been also widely employed in gas separation applications.…”

Enhanced carbon dioxide membrane‐based absorption with amino acid solutions

“…Human activity is contributing dangerously to global warming with large emissions of carbon dioxide (CO 2 ), which is one of the main greenhouse gases emitted from anthropogenic sources 1 . Fuel combustion processes for generating power are one of the main sources of CO 2 emissions 2 .…”

“…Human activity is contributing dangerously to global warming with large emissions of carbon dioxide (CO 2 ), which is one of the main greenhouse gases emitted from anthropogenic sources. 1 Fuel combustion processes for generating power are one of the main sources of CO 2 emissions. 2 With the development of technologies such as post-combustion CO 2 capture, pre-combustion, oxyfuel combustion and renewable energies, CO 2 emissions have been reduced by around 3.3%.…”

Sustainable Microcrystalline Cellulose-Based Activated Carbons for a Greener Carbon Capture at Post-Combustion Conditions

“…Chemical activation tends to be the preferred method of activation as it typically produces ACs with superior capture capacity. In addition to its use with cellulose-derived ACs, there exists an extensive array of studies in literature demonstrating the capability of AC production methods encompassing the use of chemical agents, particularly KOH (Rashidi and Yusup, 2016), (Malini et al, 2023). Whilst the effectiveness of an AC production method is important, it is important to envision its use beyond laboratory scale and consider the practicality of employing such larger scales for industrial-scale combustion capture.…”

“…These characteristics create the additional challenge of guaranteeing safe disposal of these activating agents and their by-production after their use (Ahmed et al, 2019). This environmental challenge also extends to procedures that attempt to enhance the CO 2 adsorption capacity of ACs by doping the ACs with nitrogen-rich sources such as ammonia or with some metal oxides such as copper oxide (Malini et al, 2023). Using these agents in large scale sorbent production would ultimately serve as a contradiction to one of the justifications of using physical sorbents over liquid amine solvents, that being their greater environmental friendliness in disposal.…”
