Columnar activated carbon has developed pore structure, good adsorption performance, high mechanical strength, high wear resistance, low cost, low cost, and can be regenerated multiple times. powdered activated carbon It is widely used in the treatment of waste gas and wastewater and is a filter material with high comprehensive cost performance.
However, the columnar activated carbon on the market varies in size. Many customers often ask what is the difference in the size of the columnar activated carbon when buying, and will it affect the adsorption effect?
The particle size of the columnar activated carbon has little effect on the specific surface area of the activated carbon. Therefore, although the particle size of the columnar activated carbon of the same mass is different, the total adsorption capacity is unchanged. However, after research, it is found that the particle size of the columnar activated carbon has a great influence on the surface area of the activated carbon. That is, for every tenth of the particle size reduction, the contact area of the columnar activated carbon under the same mass is ten times that of the previous one.The contact area increases, and the adsorption speed will be As a result, the smaller the columnar activated carbon particles have no effect on the adsorption effect, and the adsorption speed is significantly improved.
When the columnar activated carbon particles are small to a certain extent, they become powdery. Because the particles of the powder are small, the voids between the molecules are relatively small, which is not conducive to the circulation of air, and the pores of the finer columnar activated carbon are destroyed. , So it is easy to desorption after adsorption saturation.
Therefore, when using columnar activated carbon, it is also necessary to prevent the particles from being too fine, so as not to reach the specified filtration rate, which will affect the adsorption effect. https://www.granular-activated-carbon.com
