Amine absorber for carbon dioxide capture and processes for making and using the same

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.

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 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.
