Kelin has focused on the production and sales of activated carbon for decades. We are familiar with the application and common sense of activated carbon.
As silicon-carbon anodes become the mainstream solution for high-energy-density lithium batteries, silicon volume expansion during charge-discharge cycles remains a key industry bottleneck. Our silicon-carbon anode porous carbon — made from premium coconut shell biomass via advanced steam activation — effectively solves this problem as a core carrier and buffer material for silicon-carbon anode systems.
Activated carbon for water treatment is generally columnar particles with large specific surface area, developed micropores, high mechanical strength
Water purification relies on activated carbon to remove contaminants through physical adsorption, chemical interaction, and catalytic reduction. Its high surface area (500–1500 m²/g) and porous structure trap impurities efficiently.
Once columnar activated carbon reaches adsorption saturation, its purification efficiency for waste gases or liquids declines significantly. Therefore, periodic replacement is crucial. Under standard industrial operating conditions, the typical replacement cycle ranges from 6 to 12 months; in certain applications, this cycle is longer than that of granular activated carbon, owing to the columnar form's superior mechanical strength and lower pressure drop characteristics.
Honeycomb activated carbon is a structured form of activated carbon manufactured into a monolithic block with numerous parallel, small square or circular channels. It is widely used in industrial exhaust gas treatment and air purification systems. The honeycomb structure significantly reduces resistance to airflow while providing a large geometric surface area and good mass transfer efficiency.
In gold mining, hydrometallurgy and precious metal recovery, coconut shell activated carbon enables efficient gold adsorption, high gold loading and low attrition loss. Its ultra-high hardness and developed microporous structure ensure selective trapping of gold cyanide complexes, greatly improving gold recovery rate and production efficiency.
In industrial exhaust, spray booth, and flue gas treatment, columnar activated carbon enables simultaneous VOCs adsorption, odor removal, and harmful gas purification. Its high hardness and developed pore structure ensure efficient trapping of volatile organics and peculiar smell molecules, greatly optimizing air discharge standard and purification system stability.
In dyeing, textile, and chemical wastewater treatment, powder activated carbon enables simultaneous decolorization, odor removal, and COD reduction. Its high iodine value and low ash content ensure rapid adsorption of dye molecules and refractory organics, significantly improving effluent quality and biotreatment stability.
Ash content is one of the key indicators for evaluating the quality of coal-based granular activated carbon. Understanding how ash content affects adsorption performance, pressure drop, and operating costs allows for a more scientific selection of suitable products.
Columnar activated carbon is high efficiency adsorbent for industrial flue gas desulfurization and denitrification. It effectively removes SO2 and NOx, low ash, high strength, good regeneration performance for dry flue gas treatment.
With controllable quality and stable performance, coconut shell activated carbon excels in the purification of residual chlorine, odors, and pigments. It is suitable for a wide range of water purification scenarios and helps reduce operation and maintenance costs.
Waste incineration is one of the methods for disposing of municipal solid waste. Harmful gases are generated during the incineration process. Virgin activated carbon is utilized during this process to adsorb the resulting toxic gases and heavy metals.
We focus on the produce of various types of cylindrical, granular, powder and high level impregnated activated carbon.
