  • Patent number: 11807525
    Abstract: An object of the present invention is to provide a new form of adsorbent suitable for a motor vehicle canister. An activated carbon fiber sheet satisfies one or two or more of conditions for indices, such as a specific surface area, a pore volume of pores having a given pore diameter, and a sheet density. An embodiment, for example, may have: a specific surface area ranging from 1400 to 2200 m2/g; a pore volume ranging from 0.20 to 1.20 cm3/g for pores having pore diameters of more than 0.7 nm and 2.0 nm or less; and a sheet density ranging from 0.030 to 0.200 g/cm3.

  • Publication number: 20220161182
    Abstract: An object is to provide a new form of adsorbent suitable for a high performance canister. An adsorbent including activated carbon is used as the adsorbent for the canister and satisfies the following conditions. P0.2/100 expressed by Equation 1: P0.2/100=X÷Y×100??(Equation 1) is 18% or more, in Equation 1, X represents an amount of adsorbed n-butane gas per 100 parts by weight of the adsorbent at 25° C. under an atmosphere where a gas pressure of n-butane gas is 0.2 kPa, and Y represents an amount of adsorbed n-butane gas per 100 parts by weight of the adsorbent at 25° C. under an atmosphere where a gas pressure of n-butane gas is 100 kPa.
