Abstract
Textured sorbent material sheets provide for enhanced performance in vapor adsorbing applications over conventional sheets, systems, canisters and other emissions control equipment. The textured sorbent material sheets can be formed as part of a small, lightweight system, canister, or can be integrated into a fuel tank.
Claims19
A textured sorbent material sheet, comprising:
- an activated carbon sorbent material and a binder, the textured sorbent material sheet defining an upper surface and a lower surface wherein one of the upper surface and the lower surface comprises a texture defined by a series of hills and valleys and formed by compression, and a different one of the upper surface and the lower surface comprises a pattern,
- wherein the texture comprises one of a diamond texture, a triangular texture, or a dimpled texture,
- wherein the textured sorbent material sheet has an ASTM BWC of about 7 g/100 mL to about 30 g/100 mL, and
- wherein a depth of the pattern is less than a depth of the texture.
1 more element
A tank with integral vapor adsorption, comprising:
- a tank structure, and
- at least one textured sorbent material sheet, wherein the textured sorbent material sheet comprises an activated carbon sorbent material and a binder, the textured sorbent material sheet defining an upper surface and a lower surface wherein at least one of the upper surface and the lower surface comprises a texture defined by a series of hills and valleys, and
- at least one fastening device which fastens the textured sorbent material sheet to a surface of the tank that is not regularly immersed in volatile liquids contained within the tank.
