Products Description
Columnar activated carbon is a highly efficient adsorption material. It is processed from high-quality coal, wood or coconut shells through carbonization, activation and other techniques. It appears as black cylindrical particles with a diameter usually ranging from 1.5 to 8mm. It has a well-developed pore structure, a large specific surface area (850-1200m²/g), strong adsorption capacity, an iodine value of 800-1100mg/g, high mechanical strength (≥90%), and good chemical stability.
Ingredients
Columnar activated carbon is mainly made from the following raw materials:
Coal quality: High-quality anthracite (such as Taixi Coal, Shanxi coal)
Wood: sawdust, wood fiber
Coconut shell: Coconut shell
Other added ingredients: A small amount of binder (such as coal tar)
Shape
Appearance: Black cylindrical particles
Shape feature: A cylindrical body with uniform diameter
Surface characteristics: It has metallic luster and a porous structure

The production process of columnar activated carbon
Raw material selection
High-quality anthracite, wood or coconut shell raw materials are selected to ensure low ash content and high carbon content.
Crushing and screening
The raw materials are crushed and screened to control the particle size.
Mixing and kneading
Add an appropriate amount of binder (such as coal tar), mix evenly, and enhance the forming strength.
Extrusion molding
Formed into cylindrical particles (with diameters ranging from 1.5 to 8mm) through an extruder.
Carbonization treatment
Carbonization is carried out at high temperature (400-600℃) in an oxygen-deficient environment to remove volatile matter and form an initial pore structure.
Activation treatment
Steam or chemical activation (800-1000℃) is adopted to expand the specific surface area and enhance the adsorption performance.
Cooling and sieving
After cooling, sieve out the debris to ensure uniform particles.
Quality inspection and packaging
Test the iodine value, strength, moisture content and other indicators. After passing the test, package it.
Packaging and Transportation
Packaging method:
25kg per bag: Moisture-proof woven bags (lined with PE film), suitable for small-batch transportation.
500kg/ bag: Ton bag (FIBC), suitable for large-scale transportation.
Customized packaging: Provide vacuum packaging or special dust-proof packaging according to customer requirements.
Transportation requirements:
Avoid damp, high-temperature and strongly oxidizing environments.
Handle with care to prevent violent collisions that may cause particle breakage.
Moisture-proof measures should be taken when transporting containers.
After-sales service
Technical support: Provide product selection, application solutions and suggestions for optimizing adsorption performance.
Quality Assurance: If the product is found to be non-compliant with the technical parameters, it can be returned, exchanged or reissued.
After-sales tracking: Regularly visit customers to understand the usage effect and provide optimization plans.
Customized service: Adjust parameters such as iodine value, particle size and strength according to customer requirements.
Regeneration guidance: Provide activated carbon regeneration methods to reduce usage costs.
