Abstract: Intensification techniques are described for enhancing biocatalytic CO2 absorption operations, and may include the use of a rotating packed bed, a rotating disc reactor, a zig-zag reactor or other reactors that utilize process intensification. Carbonic anhydrase can be deployed in the high intensity reactor free in solution, immobilized with respect to particles that flow with the liquid, and/or immobilized to internals, such as packing, that are fixed within the high intensity reactor.

Abstract: Sulfurihydrogenibium sp. carbonic anhydrase (SspCA) or mutants thereof catalyze a hydration reaction of CO2 into bicarbonate and hydrogen ions or a desorption reaction to produce a CO2 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 CO2 from a CO2-containing gas.

Abstract: A formulation and process for capturing CO2 use an absorption mixture containing water, biocatalysts and a carbonate compound. The process includes contacting a CO2-containing gas with the absorption mixture to enable dissolution and transformation of CO2 into bicarbonate and hydrogen ions, thereby producing a CO2-depleted gas and an ion-rich solution, followed by subjecting the ion-rich solution to desorption. The biocatalyst improves absorption of the mixture comprising carbonate compounds and the carbonate compound promotes release of the bicarbonate ions from the ion-rich solution during desorption, producing a CO2 gas stream and an ion-depleted solution.

Abstract: A method, process, apparatus, use and formulation for dual biocatalytic conversion of CO2 containing gas into carbon containing bio-products by enzymatic hydration of CO2 into bicarbonate ions in the presence of carbonic anhydrase and metabolic conversion of the bicarbonate ions into carbon containing bio-products in a biological culture. The dual biocatalytic conversion may be relatively constant with controlling a feeding of the bicarbonate ions to the biological culture in accordance with demands of the biological culture by retaining over-production of bicarbonate ions and feeding part of the over-production to the biological culture in accordance with nutrient demands of the biological culture. Bicarbonate ions may also be reconverted to generate a pure CO2 gas stream. The CO2 containing gas may be derived from operations of a power plant which receives a carbon-containing fuel for combustion, and the biological culture may be an algae culture.
