Activated carbon and canister

摘要

This invention provides activated carbon having excellent adsorption and desorption properties and a canister using such activated carbon. An organic substance is adsorbed on a base activated carbon having pores with a wide range of diameter to selectively occlude pores with small diameters. As the pores with small diameters are occluded, the activated carbon has excellent adsorption and desorption properties. A canister using this activated carbon has a decreased leakage of an adsorbate.
