Activated carbon is widely used in the purification of alcohol, especially for applications where high purity and quality are essential. The porous structure of activated carbon provides an extensive surface area for adsorption, enabling the removal of impurities, color, odors, and unwanted flavors from alcohol.

In the ethanol industry, activated carbon can be used to remove unwanted compounds and impurities from fermentation broths or distillation products to produce high-purity ethanol for fuel or industrial applications.
