What is Activated Carbon?

It is carbon which is very adsorbent, with an exceedingly high internal surface area. It is manufactured from various raw materials including, but not limited to coal, coconut shells, macadamia nut shells, peat, and lignite. Activated carbon is used to adsorb several different kinds of molecules and compounds.

How is it Made?

At CPTech carbonaceous material, mostly coconut shells, macadamia nut shells, and wood from alien wood species is first carbonised at a high temperature, and then subjected to steam under extreme heat. This is called steam activation and the process increases the internal surface area of the carbon skeleton by creating channels through the carbon. skeleton creating a complex pore network. The millions of pores enable the activated carbon to hold onto certain molecules passed through it.

 Why is it important?

Activated carbon possesses an incredibly large surface area per volume, and no other adsorbent comes close in comparison. This makes it an ideal medium for the adsorbtion of compounds from various solutions.

How is it Used?

  • Air or gas treatment - odour and contaminant control and purification
  • Treatment of waste water and other process effluents
  • Food & Beverages - decolourisation, odour and taste removal
  • Precious metal recovery
  • Pharmaceuticals - purification of medicinal compounds, ingestible carbons
  • Water filtration - municipal supply, beverage industry, or process water streams
