Agglomerated Activated Carbon Manufacture
The most common process is high temperature steam activation though it can also be manufactured with chemicals. Along with the raw material, the activation process has a very large influence on the characteristics and performance of activated carbon.
Our main line of granular activated carbons are produced by steam activation of selected grades of pulverised and then re-agglomerated bituminous coal. Our powder activated carbon is mainly produced by pulverisation of the final product.
- A pore structure containing a good mix of both larger transport pores and smaller adsorption pores giving both high capacity and good kinetics. This results in excellent adsorption in a wide range of applications such as decolourisation and water treatment.
- The transport pores between the agglomerated particles allow the activation gases to penetrate much more within the structure of the activated carbon. The whole granule, not just the outside, is activated.
- Combined with the high mechanical strength of the coal base, these transport pores also give the carbon excellent reactivation performance.
- This process ensures the carbon can be rapidly wetted for easy application in liquid phase applications.
- By producing from a pulverised blend, the granules used in the activation process are more uniform resulting in consistent high quality products.
