    摘要： 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.

    摘要： A method for CO2 capture may include operating a packed reactor comprising a reaction chamber containing packing including immobilized enzymes, by contacting a CO2 containing gas with a liquid solution in the reaction chamber to produce an ion-loaded solution and a CO2 depleted gas by an enzymatically catalyzed hydration reaction; monitoring enzyme activity of the immobilized enzymes; at a low enzyme activity threshold (i) stopping operation in the packed reactor, and (ii) replenishing the enzymatic activity by providing an enzyme replenishing solution into the packed reactor to contact the packing and provide a replenishing amount of the immobilized enzymes; and recommencing operation in the packed reactor for CO2 capture using the replenished immobilized enzymes. A corresponding system may include a packed reactor and an in situ enzyme supply device for supplying active enzyme within the reactor. The enzyme supply device may include spray nozzles with various configurations.
