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.

Abstract: Intensification techniques are described for enhancing biocatalytic CO2 absorption operations, and may include the use of a rotating packed bed, a rotating disc reactor, a zig-zag reactor or other reactors that utilize process intensification. Carbonic anhydrase can be deployed in the high intensity reactor free in solution, immobilized with respect to particles that flow with the liquid, and/or immobilized to internals, such as packing, that are fixed within the high intensity reactor.
