Abstract

On prépare de la chaux sulfatée hydratée présentant une grande superficie et une faible granulométrie par hydratation de chaux à l'aide d'une solution d'hydratation aqueuse d'un solvant organique, et de préférence par lavage de l'hydrate obtenu à l'aide d'une solution aqueuse d'un solvant organique avant de procéder au séchage. Les hydrates de grande superficie de l'invention sont d'excellents sorbants permettant l'élimination de SO2 de courants de gaz.
