CANISTER FOR PREVENTING THE EMANATION OF A VAPORIZED FUEL GAS

摘要

A canister is provided for preventing the emanation of a vaporized fuel gas. The canister is capable of quickly heating the activated carbon through the resistance thereof up to a required temperature at the time of desorption of the vaporized fuel gas. The canister comprises a container having a vaporized fuel gas inlet port and an exit port. An aggregate of activated carbon is filled in the container to adsorb the vaporized fuel gas, and at least a pair of electrodes are provided for heating the activated carbon through the resistance thereof, at the time of desorption of the vaporized fuel gas. A highly electrically conductive activated carbon is used having an electric resistance of not larger than 500 .OMEGA./2.53 cm3.
