The invention relates to a method for the deoxygenation in a chemical loop of smokes resulting from oxidation-combustion reactions, that comprises: a first step during which the smokes are stripped from their oxygen by trapping the same by the oxidation of an oxygen-carrier material, thus producing a main flow of smokes with a reduced oxygen content; and a second step for also producing smokes that can join the main smoke flow and during which the material oxidized during the first step is reduced and regenerated by reaction with the fuel in order to be used again during said step. The invention also relates to an apparatus for implementing said method.
