Abstract (en)

[origin: WO2013159228A1] Techniques for treating CO2 containing gas include contacting the gas with an aqueous absorption solution including carbonic anhydrase as well as an absorption compound, which may be a tertiary amino compound for enzymatically enhanced flux of CO2. The absorption compound may include MDEA, TEA, DEMEA, DMMEA, TIPA or DMgly, for example. The techniques may provide concentrations to enhance the enzymatic catalysis and inhibit viscosifying of the absorption solution or enzyme denaturing that would lower the overall CO2 absorption rate. The absorption may be conducted at a temperature between about 0° C and about 80 °C, for example. Processes, uses and formulations are provided for enhanced CO2 capture.
