What is the proper mechanism of biomass activation to prepare activated carbon?
Different activation agents are using for activated carbon preparation from biomass. How different biomass and/or different activating agents produce activated carbon of different properties.

thank you for sharing this paper. Most of the details are given there, but still, this is not covering my question.
Ali Zaker thank you very much. But I am looking for the basic concept; how this activation process works. i.e., using different activation agents (KOH, K2CO3, NaOH) produce activated carbon with different properties.
Hi,
In this article, all biomass with their High specific area is defined.

In total, KOH with 1.4 ratios is the best reagent for activation at 800 C, using rice husk. Moreover, you can use from direct pyrolyze without using any reagents. The most important parameter for activation is related to the initial precursor and amount of lignin in the structure. The reagents don't have a key role in activation.
