Activated carbon
Cargen offers the appropriate activated carbon for each industrial process for which you are seeking a specific purification solution.
High-quality &
strictly selected
Our experts work with you as the client, based on concrete needs and requirements, to find the most efficient and suitable type of activated carbon.
The Cargen activated carbon range offers various possibilities. We will also monitor the performance of this activated carbon type in conjunction with you in order to ensure that it meets the required standards.
Cargen’s activated carbon range
PrisTec®
Cargen offers its range of virgin activated carbon under the brand name “PrisTec®”. PrisTec® guarantees strictly selected, high-quality activated carbon with excellent adsorption characteristics.
ReviTec®
After use, depending on the application and type, saturated activated carbon can be reactivated. Cargen ensures the reactivation of this activated carbon according to the “Closing the Loop” principle, allowing customers to rely on sustainable and high-quality reactivated activated carbon (“ReviTec®”).
ChemTec®
For specific applications and to increase removal efficiency, Cargen also offers impregnated carbon (“ChemTec®”). By means of a chemical reaction between the impregnate and the contaminant (chemisorption), components that are harder to adsorb on standard activated carbon can still be captured.
Cargen’s range of activated carbon also includes powdered (PAC), granular (GAC), and extruded (pellets) activated carbon (EAC).
Here, too, we are happy to work with you to determine which type is best suited for the specific application.
In addition to coal-based activated carbon, customers can also choose activated carbon produced from sustainable, renewable sources.
Agglomerated activated carbon is also part of the Cargen activated carbon range.
Reactivation
>>
As activated carbon is used to purify gases or liquids, it gradually becomes saturated. The most sustainable and circular solution is to reactivate this saturated activated carbon.
Through this strictly controlled thermal process, the contaminants are desorbed or removed from the activated carbon and neutralized via state-of-the-art flue gas treatment. The result of this reactivation is that the micropores, which provide the large specific surface area of the activated carbon, become available again. This allows the reactivated activated carbon to be used once again in various purification processes (ReviTec®).
Cargen handles the reactivation of the saturated activated carbon, where technically and legally feasible. In this way, activated carbon can be used more sustainably by reusing the same activated carbon over and over again.
By reactivating saturated activated carbon, Cargen meets the need to reduce waste (compared to single-use activated carbon), significantly lower CO2 emissions, and reduce the use of primary raw materials by closing the loop.

What is activated carbon?
Activated carbon is a porous organic material characterized by a very large specific surface area.
It is produced from various carbon-rich materials such as coal, wood chips, coconut shells, cocoa husks, etc. These materials are converted into activated carbon or “activated” by means of a thermal process, which removes gases and impurities from the carbon. The result of this process is an activated carbon with a very large internal surface area, ranging from 500 to 2,000 m² per gram of product.
The efficiency of activated carbon is based on this very large internal surface area with a large number of very fine pores. This allows activated carbon to attract certain gaseous or liquid molecules that flow through the activated carbon. This process is called “adsorption”. The use of activated carbon allows for the filtration and removal of unwanted molecules or contaminants from air, water, or gas. This way, a flow of water, air, or gas can be purified.
Activated carbon is available in different forms, such as extruded (pellets), powdered, and granular activated carbon. Depending on the specific application, a different type of carbon may or must be chosen.
Over time, the unwanted compounds or contaminants take up more and more space within the activated carbon. The adsorption capacity gradually decreases in line with the flow of molecules to be adsorbed. The activated carbon becomes saturated, which causes the adsorption capacity to drop too low for the desired purification process.
At this point, the activated carbon must either be replaced with fresh (“virgin”) activated carbon or, preferably, reactivated, depending on the specific application and type of activated carbon in question.
