Import Desulfurizer — Buy in wholesale FOB from Supplier in China

The desulfurizer from Wanyang Activated Carbon Co., Ltd is an iron oxide-based solid adsorbent designed to remove hydrogen sulfide and other sulfur compounds from gas streams. The product appears as a brown granular material composed primarily of refined ferric oxide, with trace additives to enhance reactivity and structural stability. It operates through a chemical reaction that converts H2S into iron sulfide, which remains bound within the media bed until regeneration or replacement.

The iron oxide content is typically above 70 percent by weight, with the remainder consisting of inert binders and pore-forming agents. The material has a bulk density of 0.8 to 1.1 g/cm³ and a surface area of 100 to 150 m²/g. It is effective at sulfur concentrations as low as 10 ppmv and can achieve breakthrough capacities of 15 to 25 percent by weight under standard conditions. The product does not release toxic byproducts and is non-flammable, making it suitable for use in confined industrial environments.

This desulfurizer is used in natural gas processing, biogas upgrading, refinery off-gas treatment, and chemical manufacturing. Buyers include gas utilities, petrochemical plants, and renewable energy operators requiring compliance with sulfur emission limits. The product is supplied in bulk bags or drums, with standard packaging of 25 kg net weight. Trade terms include FOB Qinhuangdao or CIF destination port. Lead time is approximately 30 to 45 days. Buyers should confirm the required bed depth, gas flow rate, and regeneration method before selection.

Wanyang Activated Carbon Co., Ltd is located in Chengde, Hebei Province, with a registered address in Xiabancheng.
