4mm Air Purifying Activated Carbon Pellets
Activated carbon columns are typically made from coal or coconut shell base. It is small cylindrical carbon with millions of microporous on the surface, which are used for purification and filtration of various substances such as air, water and mines.
The main function of coal based columnar activated carbon is to adsorb harmful gases, filter out insoluble substances, and adsorb some soluble substances.
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.
about lvyuan
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.
