SDG-2 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 surface adsorption force field of the SDG adsorbent, it is fixed on its surface and then interacts with it. The active ingredient undergoes a chemical reaction to generate 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 also chemical adsorption, particle adsorption, catalysis, chemical reactions, 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.
