Formed adsorber for canister

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 P0.2/100 expressed by Equation 1: P0.2/100=X÷Y×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.
