Biocatalytic gas-liquid membrane contactors for CO2 hydration with immobilized carbonic anhydrase

CO2 capture from flue gas, biogas and natural gas is still a key challenge in many environmental and energy applications. The gas-liquid membrane contactor provides a promising alternative to traditional packed towers and bubble columns. We developed a novel biocatalytic gas-liquid membrane contactor for CO2 capture with benign solvent absorbents. Both virgin and superhydrophobic PP hollow fiber membranes were investigated.
