Coal-based Pellet Activated Carbon

Excellent Adsorption Performance

· Selling Point: Coal-based cylindrical activated carbon possesses powerful adsorption capability, enabling it to rapidly and efficiently absorb harmful gases and odors in the air, as well as impurities and heavy metal ions in water. For newly renovated houses, it can effectively remove harmful gases such as formaldehyde and benzene, creating a healthy and fresh indoor environment for users. In water treatment, it can significantly reduce the Chemical Oxygen Demand (COD) and Biochemical Oxygen Demand (BOD) in water, thus improving water quality.

· Feature: It has a well-developed pore structure with pores of various sizes and wide distribution, providing a huge specific surface area for adsorption. Generally, the specific surface area of coal-based cylindrical activated carbon can reach 500 - 1500 m²/g, allowing it to fully contact and adsorb various pollutants. In addition, pores of different sizes can selectively adsorb pollutants of different molecular sizes, greatly improving adsorption efficiency.

High Mechanical Strength

· Selling Point: In practical use, activated carbon must withstand certain pressure and friction. Coal-based cylindrical activated carbon has high mechanical strength, making it resistant to breakage and wear. It can maintain its complete granular shape during long-term use and frequent loading and unloading, minimizing powder generation. This not only ensures stable adsorption performance but also reduces the risk of secondary pollution caused by carbon particle breakage during use. For example, in a fixed-bed adsorber, high-strength coal-based cylindrical activated carbon can maintain bed stability, allowing gas or liquid to pass through evenly and enhancing adsorption efficiency.

Feature: This advantage comes from its unique production process and raw material characteristics. During manufacturing, a series of treatments such as high-temperature carbonization and activation make the carbon structure denser and stronger. Meanwhile, coal itself has inherent hardness and toughness, which after processing endow the coal-based cylindrical activated carbon with excellent mechanical performance.

Good Chemical Stability

· Selling Point: Coal-based cylindrical activated carbon exhibits excellent chemical stability, capable of resisting corrosion from acids, alkalis, and other chemical substances. It can maintain stable performance in various chemical environments, making it widely applicable to complex industrial processes and harsh environments. For instance, in chemical wastewater treatment, even when dealing with acidic or alkaline wastewater, coal-based cylindrical activated carbon can still perform its adsorption function effectively without being corroded, ensuring long service life and stable adsorption performance.

· Feature: Its main component is carbon, which is chemically stable and not prone to reactions with other substances. Moreover, the special crystal structure and surface chemistry formed during production further enhance its chemical stability, allowing it to maintain its physical and chemical properties in different chemical media.

High Cost-Effectiveness

· Selling Point: Compared with other types of activated carbon, coal-based cylindrical activated carbon has relatively low production costs and a more affordable price. While ensuring excellent adsorption performance, it provides a more cost-effective solution for users. For large-scale industrial production and environmental protection projects, using coal-based cylindrical activated carbon can significantly reduce treatment costs and improve economic efficiency. For example, in large wastewater treatment plants and air purification projects, using coal-based cylindrical activated carbon in bulk can effectively control costs without compromising treatment results.

· Feature: Coal is a resource with abundant reserves and relatively low cost. The rich raw material supply ensures large-scale production and lower manufacturing costs of coal-based cylindrical activated carbon. In addition, its production process is mature and efficient, which further reduces the product price.

Reusable

· Selling Point: After reaching adsorption saturation, coal-based cylindrical activated carbon can be regenerated to restore its adsorption capacity, enabling repeated use. This not only reduces waste generation and environmental impact but also saves users the cost of purchasing new activated carbon. For example, in some industrial exhaust treatment systems, used coal-based cylindrical activated carbon can be reactivated through high-temperature or chemical regeneration methods and reused, continuing its adsorption function and improving resource utilization efficiency.

· Feature: Its adsorption process mainly involves physical adsorption, where pollutants are attached to the pore surface of activated carbon through intermolecular forces. During regeneration, methods such as heating, pressure reduction, or chemical solvents can desorb the pollutants from the surface, thereby restoring the pore structure and adsorption capacity of the activated carbon. This reusability provides significant economic and environmental advantages for coal-based cylindrical activated carbon.
