Estimating the term…
A process for capturing CO2 includes contacting a CO2-containing gas with an absorption mixture optionally within a packed reactor is provided. The absorption mixture includes a liquid solution and micro-particles. The micro-particles include a support material and biocatalyst supported by the support material and are sized and provided in a concentration such that the absorption mixture flows through the packed reactor and that the micro-particles are carried with the liquid solution to promote dissolution and transformation of CO2 into bicarbonate and hydrogen ions. The absorption mixture and micro-particles may be provided in an absorption reactor so as to be pumpable. Furthermore, a process for desorbing CO2 gas from an ion-rich aqueous mixture includes providing biocatalytic micro-particles and feeding the mixture to a desorption reactor, to promote transformation of the bicarbonate and hydrogen ions into CO2 gas and water.
