摘要
<jats:title>Abstract</jats:title> <jats:p>The objective of this work was preparation of activated carbon from spent dregs for carbon dioxide adsorption. A saturated solution of KOH was used as an activating agent. Samples were carbonized in the furnace at the temperature of 550°C. Textural properties of activated carbons were obtained based on the adsorption-desorption isotherms of nitrogen at −196°C and carbon dioxide at 0°C. The specific surface areas of activated carbons were calculated by the Brunauer – Emmett – Teller equation. The volumes of micropores were obtained by density functional theory method. The highest CO<jats:sub>2</jats:sub> adsorption was 9.54 mmol/cm<jats:sup>3</jats:sup> at 0°C – and 8.50 mmol/cm<jats:sup>3</jats:sup> at 25°C.</jats:p>
