Abstract

The physicochemical characteristics of natural zeolites from the Tayzhuzgen and Shankanay deposits have been studied by BET, SEM, XRD, and FT-IR spectroscopy. Sorption properties of natural zeolites for carbon dioxide were studied in the flow mode in the temperature range of 50-300 °C. Among the studied samples, the most active in the process of capturing CO2 was the natural zeolite of the Tayzhuzgen deposit, at a temperature of 300 °C, the adsorption capacity for carbon dioxide was 27.4%. The high CO2 adsorption capacity of natural zeolite from the Tayzhuzgen deposit is due to its specific surface area and high Si/Al ratio.
