Abstract

The rocketing CO2 emissions has caused intensified global warming effect to human beings. Although several approaches have been proposed to reduce atmospheric CO2 emissions, high temperature condition and high energy consumption make those approaches hard to carried out in industrial application. Carbonic Anhydrase (CA) catalyzed hydration reactions or aqueous solvents are a potential alternative in conventional amine-based CO2 capture, for its energy saving and excellent performance. However, free CA will significantly increase the CA amounts and system cost, as well as decreasing the system efficiency. To face the mentioned issues, some new methods of immobilization of CA are introduced, which can help to provide new ideas for alleviating greenhouse effect and global warming.
