Claims20
A reaction vessel for removing CO2 from a CO2-containing gas comprising a bottom portion containing a gas inlet and a liquid outlet, a top portion containing a liquid inlet and a gas outlet, and a middle portion containing a plurality of particles coated with carbonic anhydrase entrapped in the pores of a polymeric immobilization material, the carbonic anhydrase being capable of catalyzing hydration of CO2 into hydrogen ions and bicarbonate ions, wherein the polymeric immobilization material stabilizes the carbonic anhydrase and comprises a micellar or inverted micellar polymer.
