Abstract
The present invention generally relates to a process for the formation of a CO2-selective absorption material and/or sulfur-selective absorption material. In one embodiment, the present invention relates to a process for the formation of a CO2-selective absorption material that comprises providing a solid material, providing an amine source, contacting the solid material with the amine source to absorb amine molecules on the surface of the solid material, and contacting the absorbing amine molecules on the solid material surface with a CO2 stream such that upon contact with the amine and the solid material, CO2 binds with the amine functional group of the amine molecule, reducing the potential for the interaction of the amine functional group with the solid surface and increasing amine sites available for CO2 capture.
