SDG adsorbent is a solid granular inorganic substance with a large specific surface area. When the acid gas diffusion movement in the purified gas reaches the adsorption force field on the surface of the SDG adsorbent, it is fixed on its surface, and then interacts with the active components in it. A chemical reaction occurs to generate a new neutral salt substance which is stored in the SDG adsorbent structure. The purification of acid gas by SDG adsorbent is a multi-functional comprehensive effect. In addition to general physical adsorption, there are also chemical adsorption, particle adsorption, catalysis, chemical reaction, etc.
