Abstract: Methods for enzyme-enhanced CO2 capture include contacting a CO2-containing gas with an aqueous absorption solution at process conditions—such as high temperature, high pH, and/or using carbonate-based solutions—in the presence of Thermovibrio ammonificans carbonic anhydrase (TACA) or functional derivative thereof for catalyzing the hydration reaction of CO2 into bicarbonate and hydrogen ions and/or catalyzing the desorption reaction to produce a CO2 gas. The TACA may be provided to flow with the solution to cycle through a CO2 capture system that includes an absorber and a stripper.

The process includes contacting a CO2-containing gas with the absorption mixture to enable dissolution and transformation of CO2 into bicarbonate and hydrogen ions, thereby producing a CO2-depleted gas and an ion-rich solution, followed by subjecting the ion-rich solution to desorption. The biocatalyst improves absorption of the mixture comprising carbonate compounds and the carbonate compound promotes release of the bicarbonate ions from the ion-rich solution during desorption, producing a CO2 gas stream and an ion-depleted solution.
