Columnar activated carbon dedicated to waste gas treatment is a highly efficient adsorbent material specially developed for treating industrial waste gas. It is processed into cylindrical granules through advanced carbonization and activation processes, using high-quality coal, coconut shells, etc. as raw materials. Its surface is covered with abundant pore structures that are interconnected, forming a huge specific surface area, which can effectively capture various harmful components in waste gas, such as volatile organic compounds (VOCs), benzene series compounds, formaldehyde, hydrogen sulfide, ammonia, etc.,
-
Iodine Value: The iodine value of coal-based columnar activated carbon is generally between 300 - 600mg/g, while that of coconut shell columnar activated carbon can reach 800 - 1200mg/g. The higher the iodine value, the stronger the adsorption capacity of the activated carbon for small molecular organic pollutants, enabling it to more effectively remove trace harmful substances in waste gas.
-
Particle Size: Common diameter specifications include 1.5mm, 3.0mm, 4.0mm, 6.0mm, etc. Activated carbon with a smaller particle size has a larger exposed specific surface area when adsorbing waste gas, which can accelerate the adsorption speed. While larger particle sizes can reduce air flow resistance while ensuring a certain adsorption efficiency, being suitable for treatment scenarios with different air volumes and waste gas concentrations.
-
Specific Surface Area: Usually ranging from 500 - 1500m²/g. The huge specific surface area provides sufficient adsorption sites for waste gas molecules, enabling them to fully contact with the activated carbon and be adsorbed, thus significantly reducing the pollutant concentration in waste gas.
-
Strength: It has relatively good mechanical strength, and the compressive strength can generally reach above 80% - 95%. This enables the activated carbon to withstand the continuous impact of air flow and the vibration during the operation of equipment in waste gas treatment equipment, is not easily broken, and ensures the stability and long-term effectiveness of the adsorption process.
-
Bulk Density: Approximately between 0.4 - 0.6g/cm³. The appropriate bulk density is conducive to achieving uniform filling in the adsorption bed layer of waste gas treatment equipment, ensuring both sufficient activated carbon mass to deal with the waste gas pollution load and maintaining reasonable air flow channels so that waste gas can smoothly pass through the adsorption bed layer for purification treatment.
-
Industrial Waste Gas Purification: In the chemical industry, it can effectively adsorb various organic waste gases and acidic gases generated during the production process, such as aromatic compounds like benzene, toluene, and xylene in petrochemical industry, and sulfur dioxide in sulfuric acid production. In the coating and printing industries, it can remove volatile organic solvents in spray paint waste gas and odors emitted by printing inks. In the pharmaceutical industry, it purifies organic waste gases in synthesis workshops and fermentation tail gases. In the electronics industry, it is used to adsorb harmful gases such as fluorides and chlorides in the semiconductor manufacturing process, ensuring that waste gas meets the emission standards and reducing pollution to the atmospheric environment.
-
Malodorous Gas Treatment: For malodorous gases generated in places such as garbage treatment plants, sewage treatment plants, and livestock and poultry farms, such as sulfur-containing compounds like hydrogen sulfide, methyl mercaptan, and dimethyl disulfide, as well as nitrogen-containing compounds like ammonia and trimethylamine, columnar activated carbon dedicated to waste gas treatment can significantly reduce the concentration of malodorous gases through adsorption, improving the air quality of the surrounding environment and alleviating the adverse impacts on the lives of surrounding residents and the ecological environment.
-
VOCs Emission Reduction: For industries with key VOCs emissions, such as furniture manufacturing, automobile manufacturing, rubber and plastic processing, etc., this columnar activated carbon can effectively adsorb various VOCs volatilized during the production process, such as formaldehyde, acetaldehyde, acetone, ethyl acetate, styrene, etc., helping enterprises meet the requirements of environmental regulations on VOCs emission reduction, reducing the environmental risks and regulatory pressures faced by enterprises.
-
High Adsorption Performance: Its well-developed pore structure and high specific surface area endow it with a powerful adsorption ability for multiple pollutants in waste gas. Whether it is low-concentration or high-concentration waste gas, it can quickly and effectively adsorb harmful components therein, with high purification efficiency, which can significantly reduce the pollutant concentration in waste gas and even make it meet the emission standards.
-
Selective Adsorption: It can conduct selective adsorption according to the molecular structures and properties of different pollutants in waste gas. For example, it has a relatively strong affinity for non-polar organic pollutants such as benzene series compounds, and can also adsorb some polar gases such as hydrogen sulfide and ammonia. This selective adsorption characteristic enables precise purification treatment according to the characteristics of waste gas in different industries.
-
Adaptability to Multiple Working Conditions: It has good physical and chemical stability and can work normally under different temperature, humidity, and pressure conditions. In the range of normal temperature to a certain high temperature (generally - 20℃ - 80℃) and in waste gas environments with relatively high humidity (up to about 80%), it can still maintain good adsorption performance and can be widely used in various complex industrial waste gas treatment scenarios.
-
Low Air Resistance Characteristics: The shape design and reasonable pore structure of columnar activated carbon result in relatively low resistance when waste gas passes through the adsorption bed layer. This not only reduces the energy consumption of the waste gas treatment system and the operating costs of equipment such as fans, but also ensures that the system operates under stable air pressure, improving the reliability and operating efficiency of waste gas treatment equipment.
-
Regeneration and Utilization Potential: Columnar activated carbon after adsorption saturation can be regenerated through methods such as thermal regeneration and chemical regeneration. Thermal regeneration involves heating the activated carbon to a certain temperature to desorb the adsorbed pollutants and restore its adsorption performance. Chemical regeneration utilizes specific chemical reagents to react with the adsorbate to regenerate the activated carbon. The regenerated activated carbon can be reused, reducing the cost of waste gas treatment and also reducing resource waste and waste discharge.
-
Appearance Shape: It has a regular cylindrical shape. This shape is beneficial for uniform filling and distribution in the adsorption tower or adsorption bed of waste gas treatment equipment, ensuring that waste gas can evenly pass through the activated carbon layer, avoiding local air flow short circuits or uneven adsorption, and improving the overall adsorption effect.
-
Pore Structure: It has abundant micropore, mesopore, and macropore structures. Micropores are the main sites for adsorption and have an extremely strong adsorption ability for small molecular pollutants. Mesopores play a bridging role between micropores and macropores, facilitating the adsorption of large molecular pollutants and their diffusion inside the activated carbon. Macropores mainly provide macroscopic air flow channels, reducing the resistance when waste gas passes through, making the adsorption process smoother. This multi-level pore structure enables it to adapt to waste gas pollutants with different molecular sizes and properties, achieving a comprehensive purification effect.
-
Density Characteristics: The bulk density is moderate, generally between 0.4 - 0.6g/cm³. Such a density ensures that the activated carbon has sufficient mass in the adsorption bed layer to adsorb pollutants in waste gas, and will not cause difficulties for air flow to pass through due to excessive density, affecting the treatment capacity and operating efficiency of waste gas treatment equipment.
-
Chemical Stability: Under normal temperature and pressure, it has good chemical tolerance to most common waste gas components and does not react with pollutants in waste gas, being able to stably maintain its adsorption performance. In a certain temperature and acid-base environment range (such as temperature - 20℃ - 80℃, pH value 4 - 10), the chemical structure of the activated carbon remains basically unchanged and can effectively treat waste gas for a long time. However, under the action of high temperature (exceeding 800℃), strong oxidants (such as potassium permanganate, hydrogen peroxide, etc.), or strong acids and alkalis (such as concentrated sulfuric acid, concentrated sodium hydroxide, etc.), its chemical structure may be damaged, resulting in a decline in adsorption performance.
