Pelletized Carbon

The raw materials used for the production of our activated carbon is charcoal. There are two ways of activating the chosen base material:

Chemical activation
This involves heating the base material to temperatures between 400 and 700ºC depending on the desired result. Phosphoric acid and/or zinc chloride are added during heating. This method of activation results in activated carbon with mainly large macro-pores, making it perfect for separating colours from liquids.

Thermal activation
In thermal activation the base product is brought to temperatures higher than 900ºC. To avoid burning the material (the flash point of coal is around 570ºC) dry steam is added. This results in a very porous semi-finished product, with pore sizes ranging from small mesopores to very small micropores.

Screening, milling and pressing
The semi-finished product can then be screened, milled or pressed depending on the final application.
