Impregnated Extruded Activated Carbon for Mercury Vapor Adsorption
Product Introduction
Impregnated Extruded Activated Carbon for Mercury Vapor Adsorption is a high-performance activated carbon specifically formulated for the capture of elemental mercury (Hg⁰), oxidized mercury compounds, and organic mercury vapors.
It is widely used in industrial off-gas treatment, flue gas purification, natural gas processing, waste incineration, chlorine-alkali plants, and mercury-containing exhaust control systems.
Through precise impregnation with specialized catalytic agents, this activated carbon enables the oxidation, adsorption, and stabilization of mercury vapor, ensuring safe long-term immobilization.
Its cylindrical pellet structure provides low pressure drop, high hardness, and excellent durability, making it suitable for continuous operation under high-temperature or variable-moisture conditions.
