A method for reactivating for purposes of the reuse thereof sorbent containing unreacted CaO that is embodied in spent ash, which is generated as a consequence of the combustion in a fossil fuel-fired combustor (14) of fossil fuel in the presence of sorbent containing Ca. The sorbent containing unreacted CaO is subjected to steam having a predetermined temperature and a predetermined partial pressure operative to effect the conversion of the unreacted CaO to Ca(OH)2 whereby a fracturing of the sorbent occurs such that the Ca(OH)2 becomes exposed. Thereafter, the sorbent now containing Ca(OH)2 is reinjected into the fossil fuel-fired combustor (14) at a temperature within the fossil fuel-fired combustor (14) operative to effect the reconversion of the Ca(OH)2 to CaO.

La présente invention concerne un procédé de réactivation, aux fins de réutilisation, d'un agent de sorption contenant du CaO n'ayant pas réagi, incorporé dans de la cendre usée produite par la combustion, dans une chambre de combustion (14), d'un combustible fossile en présence d'un agent de sorption contenant du Ca. L'agent de sorption contenant le CaO qui n'a pas réagi est soumis à l'action de vapeur ayant une température prédéterminée et une pression partielle prédéterminée, qui conviennent pour exécuter la conversion du CaO n'ayant pas réagi en Ca(OH)¿2?. Il se produit alors une rupture de l'agent de sorption, si bien que le Ca(OH)¿2? devient accessible. Ensuite, l'agent de sorption, qui contient à présent du Ca(OH)¿2?, est réinjecté dans la chambre de combustion (14) brûlant un combustible fossile, à une température, à l'intérieur de cette chambre (14), qui convient pour effectuer la reconversion du Ca(OH)¿2? en CaO.
