A new molecular sieve able to extract only carbon dioxide could be useful in removing the CO2 from natural gas deposits and emissions.
Developed by a team at the University of Melbourne, the sieve is made up of chabazite, which is made up of rings of silicon, aluminum and oxygen surrounding a cesium atom. The cesium atom acts as a trap door, allowing the carbon dioxide to pass through and storing it within the structure while blocking the other chemicals.
The new method will reduce the costs of capturing and storing carbon dioxide, of which excess amounts must be removed from natural gas before the gas can be liquefied and shipped.
