Abstract
Disclosed is a formulation for the absorption of CO2, which comprises water, at least one CO2 absorption compound and a carbonic anhydrase as an activator to enhance the absorption capacity of the CO2 absorption compound. The invention also concerns the use of carbonic anhydrase, in a CO2 absorption solution to increase the CO2 absorption rate of such solution.

A formulation for catalysis of the reaction CO2+H2O⇄HCO3−+H+, comprising water and at least one reaction compound selected from N-methyldiethanolamine (MDEA), piperazine (PZ), 2-(2-aminoethylamino)ethanol (AEE), and 2-amino-2-methyl-1-propanol (AMP), the water and the at least one reaction compound forming a solution;
- and carbonic anhydrase to catalyze the reaction.
A method for catalysis of the reaction CO2+H2O⇄HCO3−+H+, comprising:
- providing a formulation in a reactor, the formulation comprising water, at least one reaction compound selected from N-methyldiethanolamine (MDEA), piperazine (PZ), 2-(2-aminoethylamino)ethanol (AEE), and 2-amino-2-methyl-1-propanol (AMP), the water and the at least one reaction compound forming a solution, and carbonic anhydrase;
- and
- operating the reactor such that the carbonic anhydrase catalyzes the reaction relative to the same formulation without the carbonic anhydrase.
A method for catalysis of the reaction CO2+H2O⇄HCO3−+H+, comprising:
- providing a formulation in a reactor, the formulation comprising water, at least one secondary or tertiary alkanolamine reaction compound, the water and the at least one secondary or tertiary alkanolamine reaction compound forming a solution, and carbonic anhydrase;
- and
- operating the reactor such that the carbonic anhydrase catalyzes the reaction relative to the same formulation without the carbonic anhydrase.
