“…This indicates that in the reaction (i), the backward reaction becomes prominent at higher temperatures due to increasing vapor pressure of Caseo,. This is similar to the Ca(OEl)4S02 reaction which shows an increasing rate of reaction upto about 1400 K and reduced sulfation at ,higher temperatures due to the decomposition of the reaction product CaSO, [6]. is provision for miXing and entry of toxic-laden gas and sorbent powder.…”

“…La figure 5 montre également que le rendement de désulfuration n'est pas modifié lorsque la pression partielle en SO 2 passe de 2500 ppm à 1400 ppm. Milne et al [10] ont également observé que le taux de désulfuration était indépendant de la pression partielle en SO 2 durant les premiers instants de la réaction, en travaillant avec du calcaire, de la chaux éteinte et des produits précalcinés. Ils ont égale-ment montré que l'ordre de la réaction devenait égal à 0,6 lorsque le taux de sulfatation était suffisant pour que la vitesse de réaction soit contrôlée par la diffusion du SO 2 à travers la couche de sulfate en construction.…”
