Rate enhancement of CO2 absorption in aqueous potassium carbonate solutions by an ammonia-based catalyst |
摘要 |
The technical field of the invention is CO2 capture and sequestration, as well as gas separation and purification technologies. In an aspect is a process for capturing purified CO2 from a CO2-containing gas, comprising steps: (a) contacting in an absorber column the CO2-containing gas with an absorption solution comprising water, ammonia, and potassium carbonate, to enable adsorption of CO2, thereby producing a CO2-depleted gas and a CO2-rich solution; and (b) subjecting the CO2-rich solution to desorption conditions in a regeneration column producing a purified CO2 gas stream and a CO2-depleted solution. |
