Estimating the term…
It is provided a method of capturing carbon dioxide from atmospheric air, the method comprising contacting the atmospheric air with a calcium chabazite having a Si/Al atomic ratio from 1.0 to 2.3 and a Ca/Al atomic ratio from 0.30 to 0.50, such that the carbon dioxide in the atmospheric air is adsorbed by the calcium chabazite and a CO2-containing calcium chabazite is obtained, wherein the atmospheric air has a CO2 content in a range from 200 ppm to 1000 ppm, wherein atmospheric air has a pressure of 1013±150 mbar; and wherein the method is carried out at a temperature from −10° C. to 50° C. It is also provided the use of a device comprising the mentioned calcium chabazite for capturing CO2 from a atmospheric air having a CO2 content from 200 ppm to 1000 ppm.
