Introduction to Activated Carbon - Coal based Columnar Activated Carbon
Keywords: activated carbon, coal columnar,Activated carbon adsorption equipment，Waste gas treatment equipment
Coal columnar activated carbon is made from high-quality anthracite as raw material, refined and processed using advanced technology, and has a black cylindrical particle appearance; Having a reasonable pore structure, good adsorption performance, high mechanical strength, easy to regenerate repeatedly, and low cost; Used for the purification of toxic gases, exhaust gas treatment, purification of industrial and domestic water, solvent recovery, and other aspects.
Coal based columnar activated carbon mainly includes two types: coal based columnar activated carbon and wood based columnar activated carbon. Wood based columnar activated carbon is mainly made of coconut shell and wood, while coal based columnar activated carbon uses natural coal as raw material and has good performance, so it is widely used in various fields.

The role of coal columnar activated carbon
(1) Coal based columnar activated carbon for household use, which has efficient air purification function and can create a comfortable and clean environment
(2) Industrial coal based columnar activated carbon is used for the purification of toxic gases, waste gas treatment, purification of industrial and domestic water, solvent recovery, and other applications.
Coal columnar activated carbon packaging:
25kg bag, lined with inner membrane bag and covered with kraft paper bag. The product should be stored indoors in a dry place.
Five application areas of coal based columnar activated carbon.
1、 The coal based columnar activated carbon used for gas purification treatment and exhaust gas treatment is made from coal as raw material, which is strictly processed through 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.
2、 Coal based columnar activated carbon can also be used for wastewater treatment, usually using high-quality coal as raw material. Its space is relatively reasonable and can effectively purify domestic and industrial water.
3、 Desulfurization and denitrification, this material is generally made of high-quality carbon raw materials, but requires the addition of a certain proportion of binders and several co catalysts. It is processed through selection, crushing, drying, and deep processing, and has many performance characteristics. It can be said to have good water resistance and low gas resistance, as well as strong compressive strength;
4、 Coal based columnar activated carbon is also required for solvent recovery treatment, which is made by physical activation method. It is black granular, odorless, non-toxic, with well-developed pores, and therefore has strong adsorption capacity. It is widely used for organic solvent recovery treatment;
5、 The application of nitrogen generators and air separation equipment is also very extensive. Nitrogen generators require specialized coal columnar activated carbon, which is suitable for deoxygenation of inert gases such as carbon monoxide and carbon dioxide, and has a good effect. Therefore, they are commonly used in these equipment.
Coal based columnar activated carbon adsorption:
Coal columnar active adsorption refers to the use of the solid surface of activated carbon to adsorb one or more substances in water, in order to achieve the goal of purifying water quality.
Factors affecting the adsorption of coal columnar activated carbon:
Adsorption capacity and adsorption rate are the main indicators for measuring the adsorption process, and the size of adsorption capacity is measured by the amount of adsorption. The adsorption rate refers to the amount of zero mass adsorbed by a unit weight of adsorbent per unit time. In water treatment, the adsorption rate determines the contact time between the wastewater and the adsorbent.
Application of coal based columnar activated carbon in wastewater treatment:
Because the coal columnar activity requires high pretreatment of water, and the price of activated carbon is expensive, the coal columnar activity is mainly used to remove trace pollutants in wastewater in wastewater treatment, which has achieved the goal of deep purification.
Introduction to the application fields of coal columnar activated carbon
Coal based columnar activated carbon is a commonly used water purification material, mainly processed from natural fruit shells, with a black appearance and cylindrical particles. It is mainly used for gas purification, sewage treatment, desulfurization and denitrification, nitrogen production, solvent recovery, and even in painting workshops. The effect is very good
