Abstract:
A particulate, heterogeneous solid CO2 absorbent composition, comprising decomposition products of Ca3Al2O6 after having been heated to a temperature between 500° C. and 925° C. in the presence of H2O and CO2 for a period of time sufficient to allow the Ca3Al2O6 to react and form the particulate, heterogeneous absorbent composition which exhibits a higher concentration of aluminum than calcium in the particle core but a higher concentration of calcium than aluminum 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 CO2 from a process gas.
