Different sorts of activated carbon can be manufactured from a wide variety of raw materials such as coal, coconut and wood. The production processes of activated carbon may be divided into chemical and thermal processes, both at elevated temperatures.

• Chemical activation is achieved by degradation or dehydration of the raw material structure, which is usually sawdust (wood-based). The DESOTEC C-PURE^® range comprises chemically activated powder activated carbon
• Steam activation can be used to activate almost all raw materials (coal-based, coconut shell-based, wood-based etc.). A variety of methods have been developed, but all of these share the same basic principle of carbonisation and initial oxidation followed by an activation step with steam. The DESOTEC AIRPEL^®, R-PURE^® and ORGANOSORB^® ranges are produced by steam activation
