Abstract:
Sulfurihydrogenibium  sp. carbonic anhydrase (SspCA) or mutants thereof catalyze a hydration reaction of CO 2  into bicarbonate and hydrogen ions or a desorption reaction to produce a CO 2  gas.  Sulfurihydrogenibium  sp. carbonic anhydrase (SspCA) having improved thermostability in the presence of carbonate ions as compared to in the absence of carbonate ions are useful in the capture of CO 2  from a CO 2 -containing gas.

Claim (Index 14):
A method for CO 2  capture, the method comprising:\n in an absorption stage: contacting a CO 2 -containing gas with an aqueous absorption solution to dissolve the CO 2  into the aqueous absorption solution, the absorption solution comprising a carbonate compound as an absorption compound; providing a recombinant  Sulfurihydrogenibium  sp. carbonic anhydrase (SspCA) having improved thermostability in the presence of carbonate ions as compared to in the absence of carbonate ions, in the absorption solution to catalyze the hydration reaction of the dissolved CO 2  into bicarbonate and hydrogen ions, thereby producing an ion-rich solution comprising at least some of the SspCA and a CO 2 -depleted gas; and in a desorption stage: providing conditions for treating the ion-rich solution comprising at least some of the SspCA, so as to desorb CO 2  gas from the ion-rich solution, thereby producing a regenerated absorption solution and a CO 2  gas stream.
