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.
