Abstract
A formulation and process for capturing CO2 use an absorption mixture containing water, biocatalysts and an absorption compound selected from dimethylmonoethanolamine (DMMEA), diethylmonoethanolamine (DEMEA), and dimethylglycine. The process may include 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.
