Adsorbents Coconut shell-based activated carbon is prepared from raw coconut shells by carbonization followed by steam activation.
Carbonization involves heating to a high temperature in an inert atmosphere.
Activation involves reaction with steam under carefully controlled conditions to develop specific pore structures and adsorptive properties. This improves material handling characteristics and is especially important where carbon fines cannot be tolerated. This allows for long life and high adsorption capacity. High retentivity, preventing unwanted desorption of adsorbed species. Examples of liquid-phase applications include gold recovery and high efficiency water purification.
