Coconut Shell Activated Carbon is a non-graphite form of carbon produced from the carbonaceous coconut shell. This is considered superior because of its smaller pores that is effective in the adsorption of gas/vapor and in the removal of odor and color. Granular activated carbon is a particularly good adsorbent due to its high surface area to volume ratio. Steam activation and chemical activation are the two commonly used processes for the manufacture of activated carbon. However coconut shell based activated carbon units are adopting the steam activation process to produce good quality activated carbon.
The process of activation is carried out in two stages. First, the coconut shell is converted into shell charcoal by carbonization process which is usually carried out in mud-pits, brick kilns and metallic portable kilns. The coconut shell charcoal is activated by reaction with steam at a temperature of 900 degree C -1100 degree C under controlled atmosphere in a rotary kiln. The reaction between steam and charcoal takes place at the internal surface area, creating more sites for adsorption. The temperature factor, in the process of activation is very important. Below 900 degree C the reaction becomes too slow and is very uneconomical. Above 1100 degree C the reaction becomes diffusion controlled resulting in loss of charcoal.
