Obtaining carbon materials for the adsorption of greenhouse gases

Abstract
Coffee-based carbon adsorbents are promising adsorbents for greenhouse gases, in particular methane, due to the possibility of creating a precision porous structure. Microporous and micromesoporous samples with a narrow pore size distribution up to 7 nm have been obtained. A study was made of methane adsorption in carbon adsorbents obtained by chemical activation at different ratios of KOH to coffee precursor. The highest adsorption of the greenhouse gas methane, equal to ~18 mmol/g at 100 bar and a temperature of 298 K, is achieved on a sample with a ratio of activating agent to carbonized precursor of 6:1 (6AKP)
Supporting agencies: The work was supported by the laboratory “Engineering of materials for systems of transportation, distribution and use of energy”.
