Patent ID: 7666507

Claim:
An element, comprising a honeycomb-shaped activated carbon paper obtained by molding a composition comprising a binder and an activated carbon satisfying b/a=0.3 through 0.55, wherein “a” is the n-butane adsorbing amount per 100 parts by weight of activated carbon at 40° C. at the concentration of n-butane being 100%, wherein “a” is measured in parts by weight, and wherein “b” is n-butane adsorbing amount per 100 parts by weight of activated carbon at 40° C. at concentration of n-butane being 1%, wherein “b” is measured in parts by weight, wherein the binder comprises pulp and at least one polyvinyl alcohol (PVA)-based binder fiber providing fire retardancy, and the activated carbon can adsorb a gasoline vapor and desorb the absorbed gasoline vapor.
