The evolution of the pore structure of coconut shells during the preparation of coconut shell-based activated carbons. In general, there are two main steps for the preparation of activated carbon: (1) the carbonization of carbonaceous precursor below 800 C, in the absence of oxygen, and (2) the activation of carbonized product (char), either using physical or chemical activation methods. The charging and discharging processes were stopped when the tube held 100 kg of char. Then, 50 g of activated carbon (AC) was immersed with a 200-mL KOH solution with a 4:1 solid-liquid ratio. Coconut shell is also a potential pre-cursor for the production of low-cost AC due to its excellent natural structure and low ash content, and provides a potentially cheap alternative to existing commercial carbons (Song et al.2014).
