Study on CO2 Adsorption of Sepoilite Modified by Mixture of Ethanolamine and N, N-Dimethyl Ethanolamine

Article Preview

Abstract:

Sepoilite was surface-modified by the mixture of ethanolamine and n, n-dimethyl ethanolamine. The XRD, SEM, FT-IR, BET and TGA were used to characterize the material structure and the adsorption property in CO2. The results showed that the weight percentage of CO2 adsorption rose from 4.01% for pure sepoilite to 19.28% for the modified sepoilite at room temperature.
