Zhengda columnar activated carbon is a high-performance material designed to purify water and filter clean air. It comes in two main types: coal-based and wood-based columnar activated carbon. This type of activated carbon is specifically engineered for efficient adsorption, making it ideal for various industrial and environmental applications. Made from high-quality raw materials such as wood chips and coconut shells, Zhengda's coal-like columnar activated carbon undergoes a multi-step process including crushing, mixing, extrusion, shaping, drying, charring, and activation. Compared to traditional coal-based activated carbon, this product has fewer impurities and a higher CTC (Carbon Tetrachloride) adsorption capacity. It is widely used in gas phase adsorption, solvent recovery, and the removal of harmful gases. In particular, our 4mm wood columnar activated carbon achieves a 100% CTC adsorption rate, which significantly outperforms standard activated carbon products that typically only reach 60-70%. This makes our product a top-tier solution that can fully replace imported alternatives. Zhengda coal columnar activated carbon is produced using advanced technology and high-quality anthracite. It features black cylindrical particles with a well-structured pore system, excellent adsorption properties, high mechanical strength, and low cost. It is commonly used in toxic gas purification, waste gas treatment, industrial and domestic water purification, and solvent recovery. Key technical specifications include: - Iodine value >800 mg/g - Strength >92% - Specific surface area >850 m²/g - Methylene blue value 120–150 mg/g - Total pore volume >0.8 cm³/g - Residual chlorine adsorption rate ≥85% - Filling density 0.45–0.55 g/cm³ The versatility of columnar activated carbon makes it suitable for a wide range of applications across industries. It is used in deodorization, desulfurization, water purification, catalyst support, gas purification, solvent recovery, food processing, and environmental protection. In the gold industry, it aids in extraction and tail liquid recovery, while in the automotive sector, it helps reduce gasoline evaporation pollution. Studies show that columnar activated carbon performs exceptionally well in removing volatile organic compounds (VOCs) from water, with removal rates ranging from 25% to 65%. The adsorption efficiency increases with the molecular weight of the VOCs. For smaller molecules, however, the adsorption performance decreases due to the limited pore size of the activated carbon. This difference in adsorption behavior between VOCs and extractable organic matter highlights the importance of molecular structure and polarity. Activated carbon, being a non-polar adsorbent, is more effective at capturing non-polar substances. For polar compounds, the adsorption efficiency tends to decrease as molecular weight increases. Overall, Zhengda coal columnar activated carbon offers strong competition in the market due to its high adsorption capacity, durability, and cost-effectiveness. With continuous improvements in production technology, it is set to play an even greater role in environmental protection and water treatment sectors. Technical parameters of Zhengda coal columnar activated carbon include: - Iodine value: ≥1000 mg/g - Benzene adsorption: ≥450 mg/g - Specific surface area: 900–1100 m²/g - Packing density: 0.5–0.55 g/cm³ - Strength: ≥90% - Moisture content: ≤10% Common specifications are available in sizes ranging from 0.5–1mm to 3–5mm. Packaged in woven bags of 25kg each, it is convenient for storage and transportation.
