Product Introduction
Yuncheng desulfurization impregnated activated carbon adopts high‑quality coal‑based columnar or coconut‑shell granular activated carbon as base‑carbon, impregnated with alkaline reagents (KOH or NaOH).
Different from physical adsorption of ordinary activated carbon, this material works via chemisorption: alkaline impregnant chemically reacts with acid‑gas H₂S / SO₂ flowing through carbon bed, generating stable solid sulfides and sulfates trapped inside pore channels, delivering high‑efficiency acid‑gas removal for industrial gas streams.
Core Highlight
Sulfur capacity ≥20%, high desulfurization efficiency, extended replacement cycle, excellent purification performance.
