Preparation of activated carbon. For the preparations of activated carbon, two basic steps are maintained. The first one is the carbonization and the second one is the activation. Carbonization is done through the pyrolysis/gasification at a higher temperature in an inert atmosphere to produce the biochar (Odetoye et al., 2019).
