SDG adsorbent is a solid granular inorganic substance with a large specific surface area. When the acid gas in the purified gas diffuses and reaches the adsorption force field on the surface of the SDG adsorbent, it is fixed on its surface and then interacts with the active ingredients in it. A chemical reaction takes place to form a new neutral salt substance and is stored in the SDG adsorbent structure. SDG adsorbent is a multi-functional comprehensive effect on the purification of sour gas. In addition to general physical adsorption, there are chemical adsorption, particle adsorption, catalysis, chemical reaction, etc. One ton of type I adsorbent can adsorb 250-300 kg of NOX, and one ton of type II adsorbent can adsorb 400-500 kg of acid.
