The use of columnar activated carbon filter for air compressor

Columnar activated carbon is mainly made of high-quality coal, coconut shell, and wood chips, and is refined through a series of production processes. Columnar activated carbon has a good adsorption effect on moisture in compressed air, and can make the removal rate of various volatile organic compounds in water reach 25%~65%.

Comparing the adsorption laws of organic compounds with different molecular weights, it can be seen that for volatile organic compounds, the larger the molecular weight, the higher their removal rate. This is similar to the adsorption law of phenol and cationic bright yellow, that is, for small molecular organic substances in water, the larger the molecular weight, the easier it is to be adsorbed by activated carbon.

Compared with the traditional coal-based columnar carbon filter, the columnar activated carbon filter has lower ash content, less impurities, gas phase adsorption value, and CTC. Coal columnar activated carbon has the advantages of developed pore structure, large specific area, strong adsorption capacity, high mechanical strength, low bed resistance, good chemical stability, easy regeneration, and durability.
