Abstract: The invention relates to a method for separating CO2 from combustion gases, which can be used at areas with large emissions (thermal power stations using any carbonaceous fuel). The separated CO2 stream can be used and/or contained in geological formations. The inventive method aims to reduce the high costs involved in CO2 separation which prevent large-scale use of the CO2 confinement options included in the UN's IPCC reports. Said method consists of bringing the combustion gases into contact with a calcareous sorbent (limestone, calcined dolomite) at 650-750° C., thereby producing the CO2 capture reaction by means of the rapid carbonation of the sorbent. The sorbent is regenerated in another reactor (calciner) which operates in CO2 or CO2/H2O atmospheres.
