How is activated carbon made?

About

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

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

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
