Study on CO₂ Adsorption of Sepiolite Modified by Silane Coupling

Abstract:

The natural sepiolite as the main raw material, removing the quartz, calcium carbonate and other impurities through purification. The purified sepiolite was roasting activation pretreatment, in order to enhance surface porosity and reaction activity, and then was made of sepiolite composite by modifying through the use of silane coupling agent. The samples were characterized by XRD、SEM、BET、FT-IR and other chemical analysis method. The weight percentage of CO₂ which were adsorbed by the modified sepiolite increased from 4% to 14.61%.
