Abstract
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.
