Abstract
An object is to provide a new form of formed adsorbers suitable for high performance canisters. A formed adsorber for a canister is to satisfy the following conditions. The formed adsorber satisfies a condition where Pexpressed by Equation 1:×100 (Equation 1)is 120% or less. In Equation 1 above, X represents an amount of n-butane gas adsorbed per 100 parts by weight of the adsorbing material at 25° C. under an atmosphere where a gas pressure of n-butane gas is 0.2 kPa, and Y represents an amount of n-butane gas adsorbed per 100 parts by weight of the adsorbing material at 25° C. under an atmosphere where a gas pressure of n-butane gas is 100 kPa.
