CO

1. A formulation for the absorption of CO 2 , comprising:

water and

at least one CO 2 absorption compound selected from the group consisting of N-methyldiethanolamine (MDEA), piperazine (PZ) and 2-(2-aminoethylamino)ethanol (AEE), forming a solution; and

carbonic anhydrase as an activator to enhance the absorption of the solution.

2. A method to activate a CO 2 absorption solution, which comprises:

contacting gaseous CO 2 with an aqueous CO 2 absorption solution comprising at least one CO 2 absorption compound selected from the group consisting of N-methyldiethanolamine (MDEA), piperazine (PZ) and 2-(2-aminoethylamino)ethanol (AEE); and

adding carbonic anhydrase to said CO 2 absorption solution while it is contacted with said gaseous CO 2 .

3. The formulation of claim 1 , wherein the carbonic anhydrase is immobilized on a support.

4. The formulation of claim 1 , wherein the carbonic anhydrase is a component of the solution.

5. The method of claim 2 , wherein the carbonic anhydrase is immobilized on a packing and the CO 2 absorption solution flows through the packing.

6. The method of claim 2 , wherein the carbonic anhydrase is directly present in and flows with the CO 2 absorption solution.

7. The formulation of claim 1 , wherein the CO 2 absorption compound comprises MDEA.

8. The formulation of claim 1 , wherein the CO 2 absorption compound comprises PZ.

9. The formulation of claim 1 , wherein the CO 2 absorption compound comprises AEE.

10. The method of claim 2 , wherein the CO 2 absorption compound comprises MDEA.

11. The method of claim 2 , wherein the CO 2 absorption compound comprises PZ.

12. The method of claim 2 , wherein the CO 2 absorption compound comprises AEE.
