AMINE ABSORBER FOR CARBON DIOXIDE CAPTURE AND PROCESSES FOR MAKING AND USING THE SAME
First Claim
1. A process for the preparation of a CO2-selective absorption material, the process comprising:
- 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.

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.

18. A process for the preparation of a sulfur containing selective absorption material, the process comprising:
-
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 sulfur containing stream such that upon contact with the amine and the solid material, the sulfur containing material 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 the sulfur containing material capture. - View Dependent Claims (19)

- 20. A CO2-selective absorber comprising an oxide material having sorbed on the surface thereof amine molecules capable of selectively capturing CO2 from a CO2-containing stream, such that at least 3 mmol/g of available sorption sites on the oxide material capture 99% of the CO2 molecules in the CO2-containing stream.
-
26. A process for the capture and removal of CO2 from a CO2-containing stream the process comprising:
-
providing a housing having dispersed therein a sorbent selective for CO2; passing a CO2-containing stream through the housing such that the CO2-containing stream contacts the sorbent; flushing the housing with steam to cause the sorbent to desorb an CO2 retained therein as a result of contact of the sorbent with the CO2-containing stream; and flushing the housing with air to remove the steam from the housing. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34)
