摘要

•Both of physical and chemical properties are improved during the ammonification.•The SO2 adsorption capacity of SSN800 can reach 175.9 mg/g at 30 °C.•SO2 adsorption capacity mainly depends on the micropore structure at 30 °C.•The nitrogen functional groups show the importance for the SO2 adsorption at 120 °C.
