Should Air Purification Use Columnar Activated Carbon or Granular Activated Carbon?

Should I use columnar activated carbon or Granular Activated Carbon for air purification? Which type of activated carbon should be used for factory waste gas purification? Now, in terms of specifications, there are two types of activated carbon, one in columnar form, and the other in two types. But when many people buy activated carbon, they don’t know which one to choose. In fact, these two types of activated carbon have different appearance and shape. In addition to the difference, there are also differences in materials. Many granular activated carbons are wood, and columnar activated carbons are mostly coal.

Granular Activated Carbon

In addition to the difference in appearance and material of air purification activated carbon, our manufacturer will also determine the quality of activated carbon based on the requirement of iodine value. The quality of Activated Carbon determines its adsorption capacity, but the better the adsorption capacity of activated carbon , Long service life and good effect. In the same way, activated carbon with low iodine value must have poor adsorption capacity and short service life!

Applicability of Columnar Activated Carbon:

1. Gas phase adsorption

2. Organic solvent recovery (benzene series gas toluene, acetone recovery in cellulose acetate industry)

3. Removal of impurities and harmful gases, recovery of waste gas

4. Recovery of excess gasoline in refineries, gas stations, and oil depots.

5. Used to catalyze the removal of HCl from tetrachloroethane on activated carbon to prepare trichloroethylene.
