Abstract

Abstract

Resin-based spherical activated carbons were prepared from four kinds of ion exchange resin(two strong basic resins D201 and D280, two weak basic resins D301G and D301R)through sulfonation, carbonization and activation treatment. The yield of the spherical activated carbons, the surface morphology and the specific surface area were characterized by thermogravimetric analysis, scanning electron microscopy and nitrogen adsorption. The adsorptive capacities of the spherical activated carbons towards CO₂ were investigated. The results showed that the yield of carbonized spheres was improved after sulfonation. The four prepared spherical activated carbon samples exhibited good adsorption performance to CO₂. The strong basic resin-based spherical activated carbons provided a higher CO₂ adsorption capacity than the weak basic resin-based spherical activated carbons. The CO₂ adsorption capacity of the spherical activated carbons obtained from strong basic resin D201 reached 2.57 mmol/g, and remained high after ten cycles.
