Import Desulfurization Activated Carbon — Buy in wholesale FOB from Supplier in China

Desulfurization Activated Carbon from Ningxia Huiheng Activated Carbon Sales Co., Ltd. is a granular carbon product formulated for the removal of hydrogen sulfide and organic sulfur compounds from gas streams. The product is derived from coal and exhibits a specific surface area of 950 to 1150 m²/g, with a pore volume of 0.55 to 0.75 cm³/g, according to the listing. Particle size is uniformly graded between 1.0 mm and 3.5 mm, minimizing pressure drop in fixed-bed reactors and reducing dust generation during handling.

The carbon is produced using steam activation, resulting in a predominantly microporous structure. It contains no chemical impregnants, making it suitable for applications where catalytic side reactions must be avoided. Ash content ranges from 7% to 11%, consistent with high-purity coal sources from northern China. Moisture content is controlled below 4%, which is critical for maintaining adsorption efficiency in dry gas environments. This formulation is typical for industrial desulfurization where physical adsorption suffices without the need for reactive media.

This product is used in natural gas purification, biogas cleanup, and flue gas desulfurization units at medium-scale industrial facilities. Buyers include gas processing plants, municipal wastewater treatment operators, and chemical manufacturers seeking reliable sulfur control without catalyst replacement. Packaging is in 20 kg or 25 kg polypropylene bags with inner moisture barriers, stacked on wooden pallets. Trade terms are typically FOB Tianjin or Lianyungang, with lead times of 12 to 18 days after order receipt. MOQ is not stated and must be confirmed directly with the supplier.

Ningxia Huiheng Activated Carbon Sales Co., Ltd. is located in Huinong District, Hongguozi Town, Ningxia Hui Autonomous Region, China. The company operates as a sales and distribution entity for activated carbon products, with its physical address indicating proximity to coal-producing regions. The listing provides no details on manufacturing capacity, workforce, or years in operation. No certifications, client references, or production process details are disclosed. The supplier is not verified as a manufacturer, and its role appears to be commercial rather than production-based.

There is no evidence in the listing of laboratory testing, quality control systems, or export experience beyond product description. The supplier does not claim ISO, SGS, or other certifications. Buyers should treat this as a trading company sourcing product from third-party manufacturers. Due diligence is required to confirm the origin of the carbon and the consistency of its technical properties. Request batch-specific test reports and verify whether the product is manufactured in-house or sourced externally.
