SO2 adsorption material, preparation method therefor and application thereof, and method for removing SO2 from flue gas containing SO2

Abstract

A SO2 adsorption material, a preparation method therefor and an application thereof, and a method for removing SO2 from flue gas containing SO2 are provided. The SO2 adsorption material contains a carbonized metal organic framework material and a sulfite loaded on the carbonized metal organic framework material, and the carbonized metal organic framework material is a carbonized material obtained by carbonizing a metal organic framework material. On the basis of the total weight of the SO2 adsorption material, the loading amount of sulfite is not higher than 10 wt %. The SO2 adsorption material has a relatively high SO2 adsorption capacity, and may be desorbed and regenerated by heating, and the adsorption capacity still remains at a relatively high level after multiple cycles of adsorption-desorption.
