   Tianyuan Coal-based Activated Carbon (Coal-based Activated Carbon, CAC) is a porous carbon material produced from high-quality anthracite and bituminous coal through processes including crushing, sieving, carbonization, activation (physical or chemical), and refining. The raw coal contains high carbon content and a significant proportion of fixed carbon. After specialized processing, it develops a highly developed pore structure, offering advantages such as large adsorption capacity, high mechanical strength, and outstanding cost-effectiveness. It has become a mainstream adsorption material in industrial wastewater treatment, flue gas purification, and solvent recovery, particularly suitable for treating high-concentration pollutants in large volumes.

I. Appearance Characteristics: The appearance of coal-based activated carbon is black granular or cylindrical. Granular products have an irregular block shape, while cylindrical products are 3-10mm in diameter and 5-15mm in length, with a smooth surface free of obvious cracks. Common particle sizes cover 4-8 mesh, 8-16 mesh, and 16-32 mesh, among which 8-16 mesh granular carbon is widely used in flue gas purification, and Φ4mm cylindrical carbon is commonly used in water treatment systems. The product color ranges from gray-black to pure black, with anthracite-based products being darker and slightly shinier due to differences in raw coal types. The bulk density is 0.55-0.75g/cm³, higher than coconut shell and wood-based activated carbon, giving it a firm and heavy feel. High-quality products have a particle integrity of ≥95%, and cylindrical products exhibit excellent compressive strength, with a breakage rate of less than 3% after drop tests, no obvious dust adhesion on the surface, and a faster initial settling speed in water compared to powdered activated carbon.

2. Core Features 1. Stable Adsorption Performance: With a BET specific surface area of 800-1200 m²/g, the material features a pore structure dominated by mesopores (2-50 nm) and macropores (>50 nm), where mesopores constitute 30%-45% and macropores 10%-20%. This optimal pore distribution ensures exceptional adsorption efficiency for macromolecular organic compounds, colloids, and suspended particles. Key performance metrics demonstrate robust performance: iodine adsorption capacity of 700-1000 mg/g, methylene blue adsorption capacity of 80-150 mg/g, and phenol adsorption capacity ≥40 mg/g. The adsorption performance shows minimal degradation under continuous operation, with a service life of 6-12 months.

2. Exceptional Mechanical Strength: Granular products achieve a mechanical strength of ≥92%, while cylindrical products demonstrate a compressive strength of ≥95MPa—far surpassing the 85% strength of wood-based activated carbon. These materials withstand dynamic conditions like water treatment backwashing and flue gas desulfurization tower impacts, resisting breakage and pulverization to minimize equipment clogging risks. With a wear resistance of ≥90%, they enable long-term reuse in fluidized bed adsorption systems, maintaining carbon powder loss at under 1% monthly.

3. Strong chemical adaptability: The product maintains a stable pH value of 7.0-10.0, neutral to weakly alkaline, resistant to acid and alkali corrosion, and can still maintain stable adsorption performance in treatment media with a pH of 2-12. The sulfur content is ≤0.8%, and the nitrogen content is ≤1.5%, preventing secondary reactions with acidic gases (such as SO₂, HCl) in the treatment system. The industrial-grade product meets the heavy metal content standards of GB/T 7701.4-2018, with arsenic ≤5mg/kg and lead ≤30mg/kg, making it suitable for industrial pollution control.

4. Superior cost-effectiveness: Anthracite coal boasts abundant reserves and widespread distribution, with mature production techniques. Compared to coconut shell activated carbon, it reduces costs by 30%-50%, making it particularly suitable for industrial applications requiring high-dose applications. Moreover, it demonstrates excellent regeneration performance—after high-temperature steam regeneration, its adsorption capacity can recover to 75%-85% of the initial value, with regeneration costs amounting to merely one-fourth of new carbon, significantly lowering overall operational expenses.

3. Application Fields 1. Industrial Wastewater Treatment: In coking wastewater treatment, Φ4mm cylindrical carbon-filled adsorption towers effectively remove phenols, cyanides, and polycyclic aromatic hydrocarbons (PAHs), achieving a phenol removal rate of over 92% and COD degradation of 40%-60%. The treated wastewater complies with the GB 16171-2012 discharge standard. For dyeing wastewater, 8-16 mesh granular carbon adsorbs reactive dyes and disperse dyes, with decolorization rates of 80%-90%. In electroplating wastewater treatment, it adsorbs heavy metal ions (e.g., chromium and nickel) at 30-80 mg/g, with removal rates exceeding 90%, and is commonly used as a deep treatment unit.

2. Flue Gas Purification Applications: In coal-fired power plant flue gas desulfurization and denitrification systems, honeycomb-structured activated carbon (specific surface area: 900m²/g) is employed to simultaneously adsorb SO₂ and NOₓ. The adsorption capacity for SO₂ ranges from 80-120mg/g, with denitrification efficiency of 30%-50%. The captured SO₂ can be converted into ammonium sulfate for recycling. For waste incineration flue gas treatment, this material effectively adsorbs dioxins and mercury, achieving a dioxin removal rate of ≥95% and a mercury adsorption efficiency exceeding 85%, fully compliant with the GB 18485-2014 standard.

3. Solvent Recovery and Oil-Gas Adsorption: In the chemical industry, granular carbon with 16-32 mesh is used to recover organic solvents such as acetone, methanol, and ethyl acetate, achieving a solvent recovery rate of ≥90%. After adsorption saturation, the carbon is regenerated through steam desorption and can be reused 5-8 times. In oil vapor recovery systems for gas stations and oil depots, its macroporous structure facilitates the diffusion and adsorption of oil vapors, achieving a recovery rate of over 95% and reducing VOC emissions.

4. Water Treatment and Environmental Engineering: In municipal wastewater treatment plants, the application of cylindrical coal-based activated carbon filters enables advanced treatment to reduce effluent COD below 30mg/L and turbidity ≤1NTU, elevating water quality to Class IV surface water standards. For drinking water treatment, these filters effectively remove residual chlorine, halogenated hydrocarbons, and odors with a 99% chlorine removal rate, improving water taste and meeting GB 5749-2022 standards. Additionally, in pure water production systems, they serve as pretreatment units to adsorb colloidal substances and organic compounds, protecting subsequent reverse osmosis membranes.

5. Industrial Applications of Catalyst Carriers: In chemical catalysis, these carriers support precious metals like palladium and platinum for hydrogenation and dehydrogenation reactions. Their stable porous structure enhances catalyst dispersion. In hydrogen peroxide production, they serve as catalyst supports for anthraquinone hydrogenation, improving both reaction efficiency and output. Additionally, they function as desulfurization agents for natural gas and coalbed methane, with a sulfur adsorption capacity of 15-25 mg/g.

4. Packaging Specifications: The product is packaged in double or triple sealed layers. Granular products are typically packaged in double layers: the inner layer is a 0.08mm-thick PE waterproof film bag to prevent moisture, and the outer layer is an 80g/m² high-strength polypropylene woven bag with a tear resistance of ≥25N. Cylindrical and honeycomb products use triple-layer packaging, with an additional kraft paper moisture-proof layer added to the double-layer structure to prevent transportation-related impact and wear.

Packaging specifications are categorized by application scenarios: Laboratory and small trial packs are available in 5kg/bag and 10kg/bag sizes, featuring sealed zippers; Standard industrial packaging comes in 25kg/bag dimensions (50cm×80cm) with reinforced handles; Bulk purchases offer 500kg/ton bags (granular charcoal) or custom-sized wooden crates (honeycomb charcoal), each equipped with forklift-compatible lifting rings. All packaging clearly displays product name, specifications (particle size/ dimensions), iodine adsorption value, production date, batch number, and quality grade. Industrial-grade and water-purification-grade products are color-coded (blue for water-purification-grade, black for industrial-grade). When sealed, the product remains stable for 2 years in cool, dry storage. Once opened, it must be resealed and used within 45 days.

5. Storage Guidelines 1. Storage Requirements: Store in a dedicated dry warehouse with temperature maintained between 0-40°C and relative humidity ≤65%. The warehouse must be equipped with ventilation and moisture-proof facilities, avoiding direct sunlight and proximity to high-temperature sources (e.g., steam pipes, heating furnaces). Place products on wooden pallets at least 15cm above the ground/walls to prevent moisture ingress. Strictly avoid mixing with strong acids, strong alkalis, oxidizers, or volatile chemicals. Maintain a minimum storage distance of 8 meters to prevent cross-contamination that may cause adsorption failure.

2. Transportation Requirements: Transport vehicles must remain dry and clean, with moisture-proof mats and waterproof fabric laid at the bottom of the cargo compartment. Handle loading/unloading with care, strictly prohibiting the tossing of cylindrical or honeycomb charcoal, and avoid violent shaking of granular charcoal to prevent breakage. During transit, implement rainproof, sunproof, and dustproof measures, and never mix with liquid cargo or sharp objects. For long-distance transport, inspect packaging integrity every 200 kilometers, promptly replace damaged sealed packaging, and ensure vehicles are equipped with dry powder fire extinguishers.

3. Handling Guidelines: When loading the adsorption tower, ensure uniform distribution to prevent voids or uneven accumulation. The particle carbon loading height should not exceed 3 meters to avoid crushing the bottom particles under pressure. For water treatment systems, perform 2-3 rinses with clean water before initial use to remove surface dust and prevent effluent contamination. During operation, regularly monitor pollutant concentrations in influent and effluent (gas). When adsorption efficiency drops below 40% of the initial value, regeneration or replacement is required. Regeneration should use high-temperature steam (350-450°C) for 8-12 hours.

4. Safety Warning: The product has a combustion temperature of 400-480°C. Open flames are strictly prohibited in storage and usage areas. Adequate dry powder fire extinguishers (no fewer than 2 units per 100㎡) must be provided, with monthly inspections of fire safety equipment. When stacking honeycomb charcoal or cylindrical charcoal, ventilation channels must be reserved to prevent heat accumulation and temperature rise. Spent saturated charcoal is classified as general solid waste and must be disposed of by qualified environmental agencies. Purified-grade charcoal must not be dumped indiscriminately to avoid soil and water contamination. Operators must wear dust masks and gloves during loading to prevent dust inhalation.
