Abstract：Calcium lignosulphonate was selected as precursor to impregnate the biochar and followed by the microwave irradiation to activate the impregnated biochar. The obtained impregnated biochar was characterized by surface area analyzer, SEM, FTIR and Raman, and then its CO2 adsorption ability was investigated. The results showed that both specific surface area and micropore volume of impregnated biochar increased with the decrease of impregnation ratio and then decreased. That was because too much lignin impregnation would block the original pores of biochar, while appropriate small amount of lignin impregnation would modulate and improve the micropore structure of biochar by entering its large size pores. The adsorption capacity of CO2 on impregnated biochar could reach 123.11mg/g, and correlation analysis demonstrated that it was influenced by both specific surface area and micropore volume. Kinetic study showed that the Avrami model fitted CO2 adsorption on biochar more accurately, indicating this adsorption process was dominated by physical adsorption and chemical adsorption. Adsorption isotherm fitting showed that Langmuir model fitted the CO2 adsorption well for the biochar with less lignin impregnation, while Freundlich model fitted the biochar with more lignin impregnation better. This indicated that appropriate small amount of lignin impregnation facilitated the formation of more uniform micropore adsorption sites on biochar. Reusability experiment showed that the adsorption capacity of impregnated biochar remained 98.22%~98.98% after 10 consecutive adsorptions-desorption cycles, indicating that it had excellent reusability. In a word, lignin impregnated biochar assisted with microwave irradiation could be a potential CO2 adsorbent.
