Sulfur Impregnated Activated Carbon for Mercury Removal

Sulfur impregnated activated carbon is a highly efficient adsorbent specifically designed for mercury (Hg) removal in industrial applications. By loading sulfur compounds onto the porous structure of activated carbon, its chemical affinity toward mercury is significantly enhanced, enabling stable fixation through the formation of mercury sulfide (HgS), mercury chloride (HgCl₂), and mercury oxide (HgO). Compared with conventional mercury removal materials, sulfur-loaded activated carbon offers superior adsorption capacity, strong chemical stability, excellent mechanical strength, and low risk of secondary pollution. This material is widely applied in natural gas purification, hydrogen production, syngas treatment, industrial tail gas control, air purification, and flue gas treatment from coal-fired power plants and waste incineration facilities. It performs effectively across varying temperature ranges and complex gas compositions, making it suitable for both low- and high-concentration mercury removal scenarios. In addition to high removal efficiency, sulfur impregnated activated carbon demonstrates strong adaptability, long service life, and cost-effectiveness. As global environmental regulations become increasingly stringent, ongoing technological advancements—such as low-temperature mercury capture and integration with multi-pollutant control systems—are expected to further expand its industrial application. Overall, sulfur impregnated activated carbon remains one of the most reliable and scalable solutions for industrial mercury pollution control.
