从United States供应商批发进口Activated Coal Carbon — FOB条款

Activated Purity Carbon LLC produces activated coal carbon from regular bituminous coal at its Wyoming operation, supplying industrial buyers in water treatment, air purification, gold recovery, and chemical processing. The material derives its adsorptive properties from thermal activation, which develops internal porosity and surface area in the coal matrix. Standard sieve sizes include 4x6, 4x8, and 10x30 US mesh, corresponding to particle ranges suited to different contactor designs and flow regimes. The 4x6 and 4x8 grades suit gravity-flow packed bed systems with lower pressure drop, while 10x30 finds use in pressurised columns and powder-fed applications where faster kinetics outweigh attrition concerns.

Bituminous coal-based activated carbon typically achieves iodine numbers between 850 and 1100 milligrams per gram, with molasses numbers reflecting mesopore development for larger molecule adsorption. The product's density, hardness, and ash content derive from the parent coal rank and activation severity. Higher activation temperatures and steam ratios increase surface area but reduce yield and mechanical hardness. For gold recovery applications, the carbon must resist abrasion in carbon-in-pulp and carbon-in-leach circuits, measured by the hardness drum test. In water treatment, the carbon's ability to adsorb chlorinated compounds, taste and odour precursors, and natural organic matter depends on the pore size distribution, particularly the balance between micropores (less than 2 nanometres) and mesopores (2 to 50 nanometres).

Primary buyers include municipal water treatment facilities, industrial wastewater plants, gold mining operations, food and beverage producers requiring dechlorination and purification, and air treatment engineers designing vapour-phase systems. The 4x8 grade dominates municipal water works for taste and odour control, while 10x30 serves powdered activated carbon feed systems for seasonal algal taste events. Gold operations typically specify 6x12 or 8x16, so buyers in precious metals recovery should confirm whether Activated Purity Carbon LLC customises outside the listed sizes. The supplier's profile states flexible minimum order quantities and competitive pricing, though exact figures require direct inquiry. Shipping terms including CIF and FOB are mentioned, but specific ports and lead times are not stated and must be confirmed with the supplier.

Activated Purity Carbon LLC maintains its registered address at 30 North Gould Street, Suite R, in Sheridan, Wyoming, United States. The supplier holds a harbor trust tier on the platform, with no response rate or average response time data available. This lack of engagement metrics means buyers should initiate contact to assess communication reliability and technical support capability. The company's geographic location in Wyoming places it near Powder River Basin coal reserves, a logical sourcing position for bituminous coal feedstock, though the listing does not confirm actual mine or plant location.

The profile does not state year of establishment, production capacity, number of employees, annual revenue, or named client references. No specific ISO, NSF, AWWA, or mining industry certifications are documented in the source material. The mention of international certifications such as ISO and SGS in the original description lacks verification and should be treated as marketing language until certificates are provided. Buyers should request current ISO 9001 registration certificates, NSF/ANSI 61 drinking water system component listings if applicable, and any mining industry quality accreditations directly from Activated Purity Carbon LLC.
