Abstract
An object is to provide an adsorbent using activated carbon fiber, the adsorbent being suitable for motor vehicle canisters and enabling reduction in pressure loss. An activated carbon fiber sheet for a motor vehicle canister fulfils the following conditions (1) to (4). (1) The sheet has a specific surface area ranging from 1100 to 2300 m2/g. (2) The sheet has a density ranging from 0.010 to 0.200 g/cm3 or less. (3) The sheet has a thickness ranging from 0.1 to 100.00 mm. (4) The sheet has a fiber size of 13.0 μm or larger.
Claims12
An activated carbon fiber sheet, comprising:
- a specific surface area ranging from 1100 to 2300 m2/g;
- a density ranging from 0.010 to 0.200 g/cm3;
- a thickness ranging from 0.10 to 100.00 mm;
- and
- a fiber size of 13.0 μm or larger,
- wherein the activated carbon fiber sheet has a ratio R0.7/2.0 equal to or more than 15% and less than 25%, the ratio R0.7/2.0 being a ratio of a volume of pores having pore sizes of 0.7 nm or less to a volume of pores having pore sizes of 2.0 nm or less.
