SDG Adsorbent is a new type of acidic waste gas adsorption material, available in two models: SDG-1 and SDG-2.

SDG Adsorbent is a solid granular inorganic substance with a large specific surface area. When acidic gases in the purified gas diffuse and reach the adsorption force field on the surface of the SDG Adsorbent, they are fixed on its surface and then undergo a chemical reaction with its active components, forming a new neutral salt substance stored within the structure of the SDG Adsorbent. The purification of acidic gases by SDG Adsorbent is a multifunctional comprehensive process, including not only physical adsorption but also chemical adsorption, particle adsorption, catalytic action, and chemical reactions.
