Iodine Value: Generally ranging from 300 to 600mg/g. The iodine value is a key indicator for measuring the adsorption capacity of activated carbon for small molecules. The iodine value within this range indicates that coal-based powdered activated carbon has a certain adsorption ability for small molecular organic compounds such as benzene, toluene, xylene, and some inorganic small molecular substances. It can effectively remove relevant pollutants and purify liquid or gas environments.
-
Particle Size: Its particle size is relatively fine. Most products can pass through an 80 - 200 mesh sieve (i.e., the particle diameter is less than 0.18 - 0.075mm). This fine particle size enables the activated carbon to be fully dispersed during the application process, greatly increasing the contact area with the substances to be adsorbed, thereby significantly improving the adsorption efficiency and ensuring that the adsorption process can be carried out quickly and comprehensively.
-
Specific Surface Area: Usually reaching 500 - 1000m²/g. The broad specific surface area provides abundant sites for adsorption, allowing it to adsorb a large number of impurity molecules. Whether it is harmful components in gases or pigments, odor substances, organic and inorganic pollutants in liquids, they can all be effectively adsorbed onto the surface of the activated carbon to achieve the purpose of purification.
-
pH Value: The pH value ranges approximately from 6 to 9. This relatively neutral pH range enables coal-based powdered activated carbon not to cause severe interference to the acid-base environment of the substances to be adsorbed in most adsorption application scenarios. It can stably play its adsorption function and ensure the smooth progress of the adsorption process.
-
Ash Content: The ash content is relatively high, generally around 5% - 15%. Ash mainly comes from the mineral components in the coal raw material. Although it will affect the purity of the activated carbon to some extent, through reasonable process control and post-treatment methods, the adverse impact of ash on the adsorption performance can be minimized under the premise of meeting application requirements.
-
Drinking Water Treatment: In the process of drinking water purification, coal-based powdered activated carbon can adsorb residual chlorine and odor substances in water, reduce the chromaticity of water, and also remove some heavy metal ions (such as mercury, lead, cadmium, etc.) and organic pollutants (such as pesticide residues, polycyclic aromatic hydrocarbons, etc.), effectively improving the water quality of drinking water, enhancing the taste, and ensuring the drinking water safety and health of residents.
-
Sewage Treatment: It is widely used in the treatment of industrial wastewater and domestic sewage. It can adsorb various harmful substances such as chemical oxygen demand (COD)-related substances, biochemical oxygen demand (BOD) components, organic dyes, phenols, and cyanides in sewage, significantly reducing the pollution degree of sewage, enabling sewage to meet the emission standards or creating favorable conditions for subsequent advanced treatment and reclaimed water reuse.
-
Food and Beverage Industry: In the production process of food and beverages, such as sugar production, winemaking, and fruit juice processing, coal-based powdered activated carbon is used for decolorization, deodorization, and impurity removal. For example, in the sugar-making process, it can adsorb pigments and some impurities in sugar liquid, improving the purity and quality of sugar, making the produced white sugar, rock sugar, etc. have a bright white color and pure taste. In winemaking and fruit juice processing, it can effectively remove unpleasant odors and impurities and enhance the flavor and stability of products.
-
Air Purification: In indoor air purifiers and ventilation systems, coal-based powdered activated carbon can adsorb harmful components in the air such as formaldehyde, benzene, TVOC (total volatile organic compounds), odors, and smoke, effectively improving indoor air quality and creating a fresh and healthy living and working environment for people. In industrial waste gas treatment, it also has a good adsorption ability for harmful gases such as volatile organic compounds (VOCs), hydrogen sulfide, and ammonia in waste gas, which can reduce the pollution of waste gas emissions to the atmospheric environment and help enterprises meet the requirements of environmental regulations.
-
Gas Masks and Respiratory Protection Equipment: As a key adsorbent filled in gas masks and respiratory protection equipment, coal-based powdered activated carbon can quickly adsorb toxic and harmful gases, effectively protecting the respiratory system of users from being invaded. It plays an indispensable and important role in the field of occupational safety protection in industries such as chemical engineering, fire protection, and mining.
-
Excellent Adsorption Performance: Thanks to its developed pore structure and large specific surface area, coal-based powdered activated carbon exhibits outstanding adsorption performance. It can quickly adsorb a variety of substances. Whether the pollutants are in low or high concentrations, they can be efficiently adsorbed by the activated carbon, thereby realizing the purification treatment of liquids or gases in a relatively short time and significantly improving the purification efficiency and effect.
-
Good Dispersibility: Due to its powdery characteristics, coal-based powdered activated carbon can quickly and evenly disperse in liquids or gases and fully contact with the substances to be adsorbed. This good dispersibility ensures that the adsorption effect can occur comprehensively and evenly, avoiding the problem of poor purification effect caused by insufficient or excessive local adsorption, making the entire adsorption process more stable and reliable.
-
Significant Cost-effectiveness: Coal, as the main raw material of coal-based powdered activated carbon, has a wide range of sources and relatively low prices, which gives coal-based powdered activated carbon an obvious advantage in production costs. In large-scale industrial applications, its relatively low cost can effectively reduce the operating costs of enterprises, while also meeting the basic adsorption requirements, having a high cost-performance ratio and strong competitiveness in the market.
-
Great Potential for Regeneration and Utilization: After the adsorption saturation of coal-based powdered activated carbon, it can be treated by various regeneration methods, such as thermal regeneration and chemical regeneration, to restore part of its adsorption performance and achieve cyclic use. This regeneration and utilization characteristic not only reduces resource waste and waste discharge, conforms to the concept of sustainable development, but also further reduces the long-term use cost of enterprises and improves the utilization rate of resources.
-
Appearance and Morphology: It appears as a black powder with no fixed shape and obvious crystal structure, and is fine and uniform in texture. This powder form enables it to be fully filled in various containers or equipment, closely contact with the substances to be adsorbed, and maximize the adsorption effect. In liquid-phase adsorption, it can be evenly dispersed in the solution; in gas-phase adsorption, it can also be well filled in the pores of the adsorption device to ensure that the gas can pass smoothly and fully interact with the activated carbon.
-
Pore Structure: It has an abundant pore system, including micropores, mesopores, and macropores. Micropores (with a pore diameter less than 2nm) are the main sites for adsorbing small molecular substances and have an extremely strong adsorption ability for small molecular pollutants such as benzene series compounds and formaldehyde. Mesopores (with a pore diameter between 2 - 50nm) play an important role in adsorbing large molecular substances and facilitating the diffusion of adsorbates inside the activated carbon, having a good adsorption effect on some large molecular organic dyes, protein-based substances, etc. Macropores (with a pore diameter greater than 50nm) mainly provide macroscopic channels, enabling the substances to be adsorbed to smoothly enter the internal pore network of the activated carbon and ensure the smooth progress of the adsorption process. This multi-level pore structure enables it to adapt to the substances to be adsorbed with different molecular sizes and properties, achieving a broad-spectrum adsorption function.
- Density Characteristics: The bulk density is relatively small, generally ranging from 0.4 to 0.6g/cm³. The small bulk density makes coal-based powdered activated carbon occupy less space during storage and transportation, which is convenient for management and operation. Meanwhile, when in use, its lighter mass is also beneficial for suspension and dispersion in liquids or gases, increasing the contact opportunities with the substances to be adsorbed and further enhancing the adsorption effect.
