4mm Air Purifying Activated Carbon Pellets
The main function of coal based columnar activated carbon is to adsorb harmful gases, filter out insoluble substances, and adsorb some soluble substances. The main components of activated carbon are made by using charcoal, various fruit shells, and high-quality coal as raw materials, which are processed and manufactured through a series of processes such as crushing, sieving, catalyst activation, rinsing, drying, and screening through physical and chemical methods.
Coal based columnar activated carbon is a cylindrical activated carbon made from high-quality selected coal as raw material and kerosene as binder, which is ground, mixed, extruded, carbonized, and activated.
Coal based columnar activated carbon has a large specific surface area, well-developed pores, high strength, strong adsorption capacity, and good chemical stability. It can be widely used in various harmful and toxic gases such as chemical, pharmaceutical, food, and microbial purification and filtration. It has a good adsorption effect on harmful gases such as benzene, alcohol, carbon tetrachloride, and chloroform with low boiling points, and can be recovered.
Technical indicators of coal based columnar activated carbon:
The specifications of coal based columnar activated carbon are 2.0/3.0/4.0/5.0/6.0/7.0mm, and the iodine adsorption value of coal based columnar activated carbon is 400-800mg/g. Generally, 3.0/4.0mm diameter is more commonly used for wastewater and waste gas purification treatment, and the iodine adsorption value is 600-800.

Characteristics and uses of coal based columnar activated carbon:
After high-temperature firing, carbonization, and activation of coal based columnar activated carbon, the internal pore size is developed, uniform, and has strong adsorption performance. It has high mechanical strength, is not easy to break, and the carbon particles are uniform. After use, regular regeneration treatment can continue to be used.
Coal based columnar activated carbon water is an adsorbent product with strong adsorption capacity, mainly used for the purification and treatment of industrial waste gas, wastewater, and domestic water, as well as solvent recycling. It can effectively remove organic molecules from wastewater, and is also widely used in the adsorption and purification treatment of industrial organic waste gas. Activated carbon is a purification principle that combines physical adsorption and chemical decomposition. It can decompose harmful gases such as formaldehyde, benzene, phenol, ammonia, and smoke in the air. The application range of columnar activated carbon is very wide.
Application fields of coal based columnar activated carbon:
Coal based columnar activated carbon is a commonly used water purification material. Mainly processed from natural coal as raw material. Black, cylindrical particles in appearance. Mainly used for gas purification, sewage treatment, desulfurization and denitrification, nitrogen production machines, and solvent recovery, painting is also required. Its effect is very good.
(1) Gas purification treatment
The coal based columnar activated carbon used for waste gas treatment is made from coal as raw material, which is strictly processed after crushing, refining, and other steps. It has a relatively large specific surface area, good pore structure, reasonable distribution, strong adsorption capacity, uniform particle distribution, and high wear resistance.
The purification treatment of gases mainly focuses on the purification treatment of chemical raw materials gases, including some organic gases, toxic gases, and other gases. It can play a very good role in separating, purifying, and purifying air.
(2) Coal based columnar activated carbon can also be used for sewage treatment.
Generally, high-quality coal is selected as the raw material, and its space is relatively reasonable, which can effectively purify domestic and industrial water.
(3) Desulfurization and denitrification
Carbon for desulfurization and denitrification is generally made from high-quality carbon raw materials, and a certain proportion of adhesives and co catalysts need to be added. It is processed through processes such as selection, crushing, drying, and deep processing. It has many performance advantages, such as good water resistance, low gas resistance, and strong compression resistance.
(4) Coal based columnar activated carbon for solvent recovery treatment
This carbon is made by physical activation method, with black granules, no taste, no toxicity, and well-developed pores. Therefore, it has strong adsorption capacity and is widely used for the recovery and treatment of organic solvents.
(5) Application of nitrogen generator and air separation equipment
The nitrogen generator requires specialized coal based columnar activated carbon, which is suitable for deoxygenation of inert gases such as carbon monoxide and carbon dioxide, with good results. Therefore, it is often used in such equipment.
Productive process :
-1) Grinding :crush coconut shell to small pieces
-2)Extruding:if you want columnar activated carbon, extruding activated carbon to pellets.
-3) Carbonation:carbonized the pellets or coconut shell powder to carbon.
-4) Activation:Physical method and chemical method.
-5)Screening: Separate different size carbon powder.
