Descripción
Modified kaolin clays were used as adsorbents for SO2 gas adsorptions. The clays were heated up to 900 C previous to acid treatments with 0.5 N sulfuric acid solutions at boiling temperature during different times up to 1440 min. Equilibrium adsorption at 25 C and 0.1 MPa was carried out by using a volumetric apparatus. The samples were characterized by chemical analysis, X-ray diffraction and infrared analysis. The heating of the clays followed by acid treatment improved the adsorption capacity of the kaolin clays. The presence of amorphous silica and hydroxyl in the final products improved SO2 adsorption capacity. Better properties for SO2 adsorption were found in kaolin rich in not well ordered kaolinite clay mineral.
