Sorption methods for capturing carbon dioxide by various sorbents

The article discusses the main methods of capturing carbon dioxide used in the processes of cleaning flue gases. The paper presents some schemes for the extraction of CO2, shows their advantages and disadvantages. The adsorption method for extracting carbon dioxide with commercial sorbents and activated carbons obtained on a coal and plant basis is considered in detail. The characteristics and properties of the main solid sorbents are given. The main indicators of the quality of activated carbons, which affect the efficiency of the extracted gas, have been established. Methods of modification of activated carbons and their influence on the sorption of carbon dioxide have been studied. As a result of the analysis of literature data and taking into account the growth of world energy consumption, it was concluded that carbon dioxide capture is a promising area of scientific research.
