Patent ID: 8329458

Claim:
A carbonic anhydrase bioreactor for treating a CO 2 -containing gas, comprising: a reaction chamber for receiving a liquid; carbonic anhydrase provided on or in substrates that are in suspension within the liquid for catalyzing a reaction of CO 2 into bicarbonate and hydrogen ions to obtain a treated gas and an ion-rich solution, wherein the substrates comprise porous substrates and the carbonic anhydrase are entrapped in the porous substrates; a liquid inlet in fluid communication with the reaction chamber for providing the reaction chamber with the liquid; a gas inlet connected to the reaction chamber for providing the CO 2 -containing gas to be treated into the reaction chamber in order to contact the liquid; a liquid outlet in fluid communication with the reaction chamber for releasing the ion-rich solution; and a gas outlet in fluid communication with the reaction chamber to release the treated gas.
