Abstract:
A particulate, heterogeneous solid CO 2 absorbent composition, comprising decomposition products of Ca 3 Al 2 O 6 after having been heated to a temperature between 500 °C and 925 °C in the presence of H 2 O and CO 2 for a period of time sufficient to allow the Ca 3 Al 2 O 6 to react and form the particulate, heterogeneous absorbent composition which exhibits a higher concentration of aluminium than calcium in the particle core but a higher concentration of calcium than aluminium at the particle surface. The invention also comprises a method for preparing the particulate, heterogeneous product as well as a method for utilizing the composition for separating CO 2 from a process gas.
