Activated carbon has a large specific surface area, good microporous structure, strong regeneration ability, is a good adsorption material.
Activated carbon can realize desulfurization and denitration at the same time, no secondary pollution and renewable utilization of resources.Preparation method of granular activated carbon is mainly physical activation method [12 and chemical activation method [3.821]. Physical activation method is to dry, carbonized materials will be first, https://yrdcarbon.com/
and then carbonized material crushing, then add to the crushing carbonized material, https://yrdcarbon.com/products/activated-carbon/
the binder and its mixing, forming and drying grain charcoal, then the granular activated carbon under a certain temperature, the final results of dry granular activated carbon products. The method commonly used activation main gas water vapor and carbon dioxide  [l ⒂ 5].
