Coal-like activated carbon is made from anthracite coal through a series of processing techniques. Its appearance is black columnar particles, with large specific surface area, developed pore structure, and high mechanical strength. It has good applications in various industrial applications. Coal-based columnar activated carbon has the characteristics of high mechanical strength, high temperature resistance, corrosion resistance, good adsorption performance, easy regeneration, economy and practicality.

The performance advantages of coal-based activated carbon make it widely used in industrial waste gas treatment. The purification efficiency, adsorption capacity, service life and regeneration capacity of columnar activated carbon are very superior. Columnar activated carbon also has a great advantage in terms of price. Generally, the amount of activated carbon used in gas treatment is larger, and the input cost is higher. However, the price of columnar activated carbon is lower than that of coconut shell activated carbon, nut shell activated carbon and other products. The price is relatively low, thereby reducing the economic cost of the enterprise, so the coal-based columnar activated carbon is particularly suitable for use in industrial waste gas.

In industrial waste gas treatment, when coal-based columnar activated carbon is selected as the adsorbent, the adsorption capacity of activated carbon is an important factor, and the adsorption efficiency of activated carbon is also related to the pressure of the adsorbed gas through the activated carbon layer. Coal columnar The activated carbon carbon layer will leave a large number of voids when laying, which reduces the gas flow resistance in the activated carbon carbon layer, and can effectively improve the treatment efficiency of the activated carbon on the adsorption and purification of exhaust gas.

The efficiency of coal-based pellet activated carbon in gas treatment is very good, and its use method and service life are very good in the same type of activated carbon products. In addition, the regeneration capacity of coal-based columnar activated carbon is relatively good, and the activated carbon can continue to be used through regeneration treatment. This is also a very advantageous condition in industrial waste gas treatment.
