Sometimes the specification will be a measurable change like color, but in other cases the specification maybe based on a taste profile. To successfully apply activated carbon to your process, it is important to carefully define the desired specification for the final treated product. Typical uses of activated carbon in distilled spirts are: The force is very strong, but works over short distances only and is sensitive to the distance between the carbon‘s surface and the adsorbate molecule. While particles may be removed, there is no significant filtration action. Adsorption is caused by London dispersion forces, a type of Van der Waals Force which exists between molecules. The varied pore structure gives the carbon its very large surface area (approximatley 2500 m 2 /g) and also allows the carbon to adsorb a wide range of compounds.Īctivated carbon works by adsorbing the compounds it is removing. It differs from graphite by having a random imperfect structure which is highly porous over a broad range of pore sizes which can be divided into three groups: Activated carbon mainly consists of elementary carbon in a graphite like structure. and O.D.Activated carbon filtration is used to effectively clean spirits by removing impurities.
