Patent number: 10226733Abstract: 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.Type: GrantFiled: November 23, 2016Date of Patent: March 12, 2019Assignee: CO2 SOLUTIONS INC.Inventors: Sylvie Fradette, Julie Gingras, Jonathan Carley, Glenn R.
