carbon capture technologiesEurekAlert!
•90% Informative
Chemists at the University of California, Berkeley , have discovered that a porous material can act like a sponge to capture CO2 at temperatures close to those of many industrial exhaust streams.
The dominant method for capturing carbon from power or industrial plant emissions employs liquid amines to absorb CO2.
The material features a porous, crystalline array of metal ions and organic linkers, with an internal area equivalent to about six football fields per tablespoon.
The metal hydride MOF has CO2 capacities comparable to the amine-appended MOFs, though at much higher temperatures.
Once the MOF is filled with CO2, the CO2 can be removed, or desorbed, by lowering the partial pressure of CO2.
The MOF can then be reused for another adsorption cycle.
