Chemical process activated carbon production line video

Phosphoric acid chemical method uses phosphoric acid as an activator to react with raw materials (wood chips, fruit shells, etc.) at high temperature. Its advantages are:

Developed pores: The corrosiveness of phosphoric acid can directionally expand the microporous structure of the raw materials and improve the adsorption performance .
High yield: The activation temperature is lower than the physical method (water vapor/carbon dioxide activation), the raw material carbon loss is small, and the yield is high.
