FAQ About Activated Carbon Product
CTC (Carbon Tetrachloride) is an important indicator of activated carbon’s adsorption capacity for large organic molecules. Specifically, it refers to the ability of activated carbon to adsorb carbon tetrachloride vapor under specific conditions.
A higher CTC value generally indicates better adsorption performance of the activated carbon.

Mesh count is a unit of measurement for activated carbon particle size, defined as the number of openings on a 1-inch (25.4 mm) long sieve. A higher mesh count indicates finer activated carbon particles.
Common mesh sizes: 4*8, 5*10, 6*12, 8*16, 8*30, 12*40, 30*60, 80*150, 200, 325, etc. Customization supported.

The iodine value refers to the number of milligrams (mg/g) of iodine that 1 gram of dry activated carbon can adsorb under specified conditions.
The higher the value, the more developed the microporous structure, the larger the specific surface area, and the stronger the adsorption capacity of the activated carbon.
Coconut shell activated carbon is more suitable for microporous adsorption scenarios such as gas phase and drinking water purification. Coal-based activated carbon is more suitable for industrial wastewater, macromolecular pollutant treatment and cost-sensitive applications.
1. Physical Adsorption
Activated carbon possesses a highly developed microporous structure (especially micropores <2 nm). Hâ‚‚S molecules are first physically adsorbed into these micropores.
2. Chemisorption
This is the main mechanism for impregnated activated carbon (KOH/MgO/NaOH/CuO, etc.). The active components on the activated carbon surface undergo neutralization, complexation, and precipitation reactions with Hâ‚‚S to generate stable sulfides or sulfates.
3. Catalytic Oxidation
Many desulfurization activated carbons possess catalytic properties, enabling them to oxidize Hâ‚‚S into elemental sulfur (S) or sulfates using a small amount of oxygen in the air. This can significantly increase the desulfurization capacity of activated carbon and extend its service life.
