Coal-based columnar activated carbon is a black cylindrical particle made from high-quality anthracite through crushing, carbonization, activation, washing and other processes. It has the characteristics of developed pores, large specific surface area (400-1200 m²/g), high mechanical strength (≥92%), easy regeneration and low cost. Its core adsorption performance index iodine value can reach 800-1200 mg/g, and methylene blue adsorption value is 120-150 mg/g. It is widely used in water treatment, waste gas purification, chemical catalysis and other fields, and is known as the "all-rounder" in the environmental protection industry.

Characteristic：

1.Efficient adsorption

Water treatment: It can deeply remove 99% of BOD and micro-pollutants (such as phenols and pesticide residues) in water, helping to reuse urban sewage.

Waste gas treatment: The adsorption efficiency of harmful gases such as VOCs, formaldehyde, benzene, etc. is more than 85%, and it is widely used in chemical and spray workshops.

2.Economical and environmentally friendly

The recycling rate is high and can be reused through thermal regeneration or steam desorption, reducing the operating costs of enterprises.

No secondary pollution, in line with environmental emission standards, adapted to the biological activated carbon process (combined with microbial degradation) to improve the treatment efficiency.

Application areas:

1. Water treatment industry

Industrial wastewater: refineries and petrochemical plants use pretreatment (coagulation and precipitation) combined with activated carbon adsorption to increase COD removal rate to 64%.

Drinking water purification: Used in conjunction with ozone to remove residual chlorine and odor to ensure water quality safety.

2. Air purification

Indoor formaldehyde and automobile exhaust treatment, with stable adsorption efficiency; toxic gas filtration in protective equipment.

3. Industrial catalysis and recovery

As a catalyst carrier (precious metals such as palladium and platinum), it is used for petrochemical desulfurization and solvent recovery.

4. Emerging fields

Gold refining, food decolorization, and ultrapure water preparation in the electronics industry.

Coal-based columnar activated carbon, with its high efficiency, economy and adaptability to multiple scenarios, has experienced explosive growth against the backdrop of increasingly stringent environmental protection policies. With the continuous innovation of production processes (such as the use of weakly sticky coal and optimization of regeneration technology), its potential in water treatment, carbon neutrality and other fields will be further unleashed, becoming one of the core materials to promote the development of green industry.
