An apparatus for adsorbing fuel vapor having a fuel vapor inlet communicating to a fuel tank, a mixed gas outlet communicating to the intake passage of an internal combustion engine, a desorbent air inlet communicating to the atmospheric air and an adsorbent for adsorbing the fuel vapor introduced from the fuel tank. The adsorbent includes an integrally formed activated carbon having a monolithic honeycomb structure having many through passages.

An apparatus for adsorbing fuel vapor comprising a container; a fuel vapor inlet for introducing the fuel vapor into the container; a gas outlet for taking the air-fuel mixture out from the container; an air inlet for introducing desorbing air into the container; and an adsorbent, being set in the container, for adsorbing the fuel vapor, said adsorbent including first, second and third monolithic structures each having many through passages separated by walls, at least one of said structures being constructed of integrally formed activated charcoal, said structures being so laminated together that the vapor/gas path through the three passage groups provided by said first, second and third structures are of zigzag configuration, the two opposite ends of the laminated product being fitted with plates for closing said ends with said ends being partially open by so designing the shape of said plates or providing said plates with holes, one of said partially open ends comprising a fuel vapor inlet and the other a desorbent air inlet, and said two partially open ends being arranged at positions not mutually confronting. An apparatus for adsorbing fuel vapor comprising: a container, a fuel vapor inlet for introducing the fuel vapor into the container; a gas outlet for taking the air-fuel mixture out from the container; an air inlet for introducing desorbing air into the container; and an adsorbent being set in the container, for adsorbing the fuel vapor, said adsorbent comprising a plurality of integrally formed activated charcoal monolithic honeycomb structures each provided with many through passages separated by walls, said structures being laminated in series so that their passages mutually communicate, the passage groups of said structures having pitches different from one another so as to form a disturbance in the flow of fuel vapor passing through the laminated product.
