A charcoal canister is part of the evaporative emission control (EVAP) system in many modern automobiles, which is designed to keep gasoline from evaporating into the atmosphere.ather than venting a gas tank to the atmosphere, an EVAP system can allow fumes to flow into a canister that contains activated carbon and is therefore capable of adsorbing the fuel vapor.
Activated charcoal is a special form of carbon that can bind other substances on its surface (adsorption). That is why it is used for water filtration. It is also used to adsorb drugs in the gut so the drugs don't enter the body. Activated charcoal is made by burning carbon-rich materials, such as wood, at very high temperatures to create charcoal. The resulting product is a black, odorless powder.
